+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE

+ Releasing 0.9.35. -CG
+
+Thu Apr 10 09:39:38 CEST 2014
+ Removed unescaping for URI path (#3371) as '+' should not
+ be converted to space in accordance with
+ http://www.w3.org/TR/html401/appendix/notes.html#ampersands-in-uris
+ and http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4.1
+ Note that we now also no longer convert '#38;' to '&'; if needed,
+ the application needs to apply unescaping to the path of the URI
+ itself (before, MHD unescaped '#38;' but not '&', so this
+ inconsistency was now resolved by simply not unescaping anything
+ before the first '&'). -CG
+
+Tue Apr 08 15:35:44 CET 2014

+ Cleanup and refactoring of configure.ac.
+ m4 macros updated.
+ Custom configure macros replaced with autoconf archive macros.
+ SPDY disabled by default on W32.
+ Changed configure flag from '--disable-pipe' to
+ '--enable-socketpair'.

+ usage. -EG
+
+Wed Feb 26 17:42:34 CET 2014
+ Refactoring of configure.ac: custom macros replaced with macros

+ W32: fixed .dll resource compilation with '-isystem' CPPFLAG.
+ W32: improved header compatibility with MSVC.
+ W32: now tested on Win64, compiled by MinGW-w64. -EG

+Thu Feb 20 14:17:05 CET 2014

+Tue Feb 18 19:46:45 CET 2014

+Sat Feb 8 15:08:35 CET 2014
+ Corrected some uses of 'int' vs. 'size_t'. -EG/CG
+
+Wed Jan 22 09:44:33 CET 2014
+ MHD_USE_DUAL_STACK in libmicrohttpd currently just *inhibits
+ setting* the IPV6_V6ONLY socket option, but per Microsoft's
+ documentation the default on Windows is that this is enabled, thus
+ MHD_USE_DUAL_STACK will not work (since it leaves the
+ default). libmicrohttpd should probably just unconditionally set
+ IPV6_V6ONLY to the desired value when the option is available. -LJ

+ Releasing 0.9.32. -CG
+
+Tue Dec 3 21:05:38 CET 2013
+ Signaling n times for shutdown works, but for resume we need to
+ wake up the correct daemon. Even if we signal n times in that
+ case also, there's no guarantee that some daemon can't run
+ through its select loop more than once before the daemon we want
+ to wake up gets a chance to read. Thus we need a signal pipe
+ per thread in the thread pool IF MHD_suspend_connection is used.
+ This introduces a new flag MHD_USE_SUSPEND_RESUME to add those
+ additional pipes and only allow MHD_suspend_connection to be
+ used in conjunction with this flag.
+
+ Also, as MHD_resume_connection() will be called on a non-daemon
+ thread, but none of the queue insert/delete calls are thread safe,
+ we need to be concerned about (a) corrupting the queue, and (b)
+ having to add mutex protection around every access to the queues,
+ including loops through timer queues, etc. This wasn't a problem
+ before adding resume; even suspend should be safe since it happens
+ in a callback from the daemon.
+
+ I think it's easier to (a) have MHD_suspend_connection() move the
+ connection to a suspended queue, (b) have MHD_resume_connection()
+ mark the connection as resuming, and then (c) do all the actual
+ queue manipulations in MHD_select (poll, epoll, etc.) to move the
+ resumed connections back to their normal queues, in response to
+ the wake up. The changes are simpler & cleaner. There is a cost to
+ the basic select loop that is avoided by making suspend/resume a
+ startup option. The per-worker pipes can then also be enabled only
+ with that option set. -MH
+
+Fri Nov 29 20:17:03 CET 2013
+ Eliminating theoretical stack overflow by limiting length
+ of URIs in authentication headers to 32k (only applicable
+ if the application explicitly raised the memroy limits,
+ and only applies to MHD_digest_auth_check). Issue was
+ reported by Florian Weimer. -CG
+
+Tue Nov 26 01:26:15 CET 2013
+ Fix race on shutdown signal with thread pool on non-Linux
+ systems by signalling n times for n threads. -CG

+Sun Nov 24 13:41:15 CET 2013

+Fri Sep 20 17:01:37 CEST 2013
+ Improved configure checks for cURL. -CG

+Wed Sep 18 18:29:24 CEST 2013
+ Signal connection termination as OK (and not as ERROR) if the
+ stream was terminated by the callback returning
+ MHD_CONTENT_READER_END_OF_STREAM. Also, release response
+ mutex before calling the termination callback, to avoid
+ possible deadlock if the client destroys the response in

+Wed Sep 18 14:31:35 CEST 2013

+ Added ability to specify external unescape function.
+ "microhttpd.h" now includes the right headers for GNU/Linux

+ Releasing libmicrohttpd 0.4.4. -CG
+
+Wed Oct 14 14:37:37 CEST 2009
+ Fixing (rare) deadlock due to SELECT missing SIGALRM by
+ making all SELECT calls block for at most 1s. While this
+ can in (rare) situations delay the shutdown by 1s, I think
+ this is preferable (both performance and possibly portability-wise)
+ over using a pipe for the signal. -CG
+
+Sun Oct 11 14:57:29 CEST 2009
+ Adding eCos license as an additional license for the
+ non-HTTPS code of MHD. -CG

+Thu May 14 21:20:30 MDT 2009
+ Fixed issue where the "NOTIFY_COMPLETED" handler could be called
+ twice (if a socket error or timeout occured for a pipelined

+
+Sun Aug 24 13:05:41 MDT 2008
+ Now handling clients returning 0 from response callback
+ as specified in the documentation (abort if internal

+ Restructured the code (curl-testcases and zzuf testcases
+ are now in different directories; code examples are in
+ src/examples/).
+ Fixed a problem (introduced in 0.2.3) with handling very
+ large requests (the code did not return proper error code).
+ If "--enable-messages" is specified, the code now includes
+ reasonable default HTML webpages for various build-in
+ errors (such as request too large and malformed requests).
+ Without that flag, the webpages returned will still be
+ empty.
+ Started to add zzuf-based fuzzing-testcases (these require

+
+Fri Apr 11 20:20:34 MDT 2008
+ I hereby dub libmicrohttpd a GNU package. -Richard Stallman
+
+Sat Mar 29 22:36:09 MDT 2008

+ persist until time-out, if any). -CG
+
+ Updated and integrated TexInfo documentation. -CG
+
+Tue Mar 25 13:40:53 MDT 2008
+ Prevent multi-part post-processor from going to error
+ state when the input buffer is full and current token
+ just changes processor state without consuming any data.
+ Also, the original implementation would not consume any
+ input in process_value_to_boundary if there is no new
+ line character in sight. -AS
+
+ Remove checks for request method after it finished writing
+ response footers as it's only _pipelined_ requests that
+ should not be allowed after POST or PUT requests. Reusing
+ the existing connection is perfectly ok though. And there
+ is no reliable way to detect pipelining on server side
+ anyway so it is the client's responsibility to not send new
+ data before it gets a response after a POST operation. -AS

+Wed Jan 30 23:15:44 MST 2008
+ Added support for nested multiparts to post processor.

+ Improvements and bugfixes to post processor implementation. - AS
+
+Wed Dec 19 21:12:04 MST 2007
+ Implemented chunked (HTTP 1.1) downloads (including
+ sending of HTTP footers). Also allowed queuing of
+ a response early to suppress the otherwise automatic
+ "100 CONTINUE" response. Removed the mostly useless
+ "(un)register handler" methods from the API. Changed
+ the internal implementation to use a finite state
+ machine (cleaner code, slightly less memory consumption).
+ Releasing libmicrohttpd 0.2.0. - CG
+
+Sun Dec 16 03:24:13 MST 2007
+ Implemented handling of chunked (HTTP 1.1) uploads.
+ Note that the upload callback must be able to
+ process chunks in the size uploaded by the client,
+ MHD will not "join" small chunks into a big
+ contiguous block of memory (even if buffer space
+ would be available). - CG
+
+Wed Dec 5 21:39:35 MST 2007
+ Fixed race in multi-threaded server mode.

+
+Sat Nov 17 00:55:24 MST 2007

+Sun Sep 9 14:32:23 MDT 2007
+ Added option to compile debug/warning messages;

+ non-public symbols (further reduces binary size).
+ Releasing libmicrohttpd 0.1.0. - CG
+
+Sat Sep 8 21:54:04 MDT 2007
+ Extended API to allow for incremental POST
+ processing. The new API is binary-compatible
+ as long as the app does not handle POSTs, but
+ since that maybe the case, we're strictly speaking
+ breaking backwards compatibility (since url-encoded
+ POST data is no longer obtained the same way). - CG
+
+Thu Aug 30 00:59:24 MDT 2007
+ Improving API to allow clients to associate state
+ with a connection and to be notified about request
+ termination (this is a binary-compatible change). - CG
+ Fixed compile errors under OS X. - HL
+
+Sun Aug 26 03:11:46 MDT 2007
+ Added MHD_USE_PEDANTIC_CHECKS option which enforces
+ receiving a "Host:" header in HTTP 1.1 (and sends a
+ HTTP 400 status back if this is violated). - CG
+
+Tue Aug 21 01:01:46 MDT 2007
+ Fixing assertion failure that occured when a client
+ closed the connection after sending some data but
+ not the full headers. - CG
+
+Sat Aug 18 03:06:09 MDT 2007
+ Check for out of memory when adding headers to
+ responses. Check for NULL key when looking
+ for headers. If a content reader callback
+ for a response returns zero (has no data yet),
+ do not possibly fall into busy waiting when
+ using external select (with internal selects
+ we have no choice). - CG
+
+Wed Aug 15 01:46:44 MDT 2007

+
+Basic Installation
+==================
+
+ Briefly, the shell command `./configure && make && make install'
+should configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package. Some packages provide this
+`INSTALL' file but do not implement all of the features documented
+below. The lack of an optional feature in a given package is not
+necessarily a bug. More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+ The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system.
+
+ Running `configure' might take a while. While running, it prints
+ some messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package, generally using the just-built uninstalled binaries.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation. When installing into a prefix owned by root, it is
+ recommended that the package be configured and built as a regular
+ user, and only the `make install' phase executed with root
+ privileges.
+
+ 5. Optionally, type `make installcheck' to repeat any self-tests, but
+ this time using the binaries in their final installed location.
+ This target does not install anything. Running this target as a
+ regular user, particularly if the prior `make install' required
+ root privileges, verifies that the installation completed
+ correctly.
+
+ 6. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+ 7. Often, you can also type `make uninstall' to remove the installed
+ files again. In practice, not all packages have tested that
+ uninstallation works correctly, even though it is required by the
+ GNU Coding Standards.
+
+ 8. Some packages, particularly those that use Automake, provide `make
+ distcheck', which can by used by developers to test that all other
+ targets like `make install' and `make uninstall' work correctly.
+ This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you can use GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'. This
+is known as a "VPATH" build.
+
+ With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory. After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+ On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor. Like
+this:
+
+ ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CPP="gcc -E" CXXCPP="g++ -E"
+
+ This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+ By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them. In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+ The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+ The first method involves providing an override variable for each
+affected directory. For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'. Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated. The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+ The second method involves providing the `DESTDIR' variable. For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names. The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters. On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+ Some packages offer the ability to configure how verbose the
+execution of `make' will be. For these packages, running `./configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with `make V=1'; while running `./configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+ On HP-UX, the default C compiler is not ANSI C compatible. If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+ ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+ HP-UX `make' updates targets which have the same time stamps as
+their prerequisites, which makes it generally unusable when shipped
+generated files such as `configure' are involved. Use GNU `make'
+instead.
+
+ On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file. The option `-nodtk' can be used as
+a workaround. If GNU CC is not installed, it is therefore recommended
+to try
+
+ ./configure CC="cc"
+
+and if that doesn't work, try
+
+ ./configure CC="cc -nodtk"
+
+ On Solaris, don't put `/usr/ucb' early in your `PATH'. This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.
+
+ On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'. It is recommended to use the following options:
+
+ ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on. Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS
+ KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+ Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf limitation. Until the limitation is lifted, you can use
+this workaround:
+
+ CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+ Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+ Print a summary of the options unique to this package's
+ `configure', and exit. The `short' variant lists options used
+ only in the top level, while the `recursive' variant lists options
+ also present in any nested packages.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+ Use DIR as the installation prefix. *note Installation Names::
+ for more details, including other options available for fine-tuning
+ the installation locations.
+
+`--no-create'
+`-n'
+ Run the configure checks, but stop before creating any output
+ files.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE

+About
+=====
+
+GNU libmicrohttpd is a GNU package offering a C library that provides
+a compact API and implementation of an HTTP 1.1 web server (HTTP 1.0
+is also supported). GNU libmicrohttpd only implements the HTTP 1.1
+protocol. The main application must still provide the application
+logic to generate the content.
+
+Additionally, a second, still very experimental library is provided
+for SPDY (the base for HTTP 2.0) support. libmicrospdy provides a
+compact API and implementation of SPDY server. libmicrospdy currently
+only implements partially version 3 of SPDY.
+
+
+Installation
+============
+
+If you are using Subversion, run "autoreconf -fi" to create configure.
+
+In order to run the testcases, you need a recent version of libcurl.
+libcurl is not required if you just want to install the library.
+
+Especially for development, do use the MHD_USE_DEBUG option to get
+error messages.
+
+
+Requirements for libmicrospdy
+=============================
+
+The following packages are needed to build libmicrospdy:
+
+* zlib
+* OpenSSL >= 1.0.1
+
+To run the test cases, involving requests, version of Spdylay, supporting
+SPDY v3, is required. Spdylay is still under development and can be
+found here:
+
+http://spdylay.sourceforge.net/
+
+
+Configure options
+=================
+
+
+If you are concerned about space, you should set "CFLAGS" to "-Os
+-fomit-frame-pointer" to have gcc generate tight code.
+
+You can use the following options to disable certain MHD features:
+
+--disable-https: no HTTPS / TLS / SSL support (significant reduction)
+--disable-messages: no error messages (they take space!)
+--disable-postprocessor: no MHD_PostProcessor API
+--disable-dauth: no digest authentication API
+--disable-epoll: no support for epoll, even on Linux
+
+The resulting binary should be about 30-40k depending on the platform.
+
+
+Portability
+===========
+
+The latest version of libmicrohttpd will try to avoid SIGPIPE on its
+sockets. This should work on OS X, Linux and recent BSD systems (at
+least). On other systems that may trigger a SIGPIPE on send/recv, the
+main application should install a signal handler to handle SIGPIPE.
+
+libmicrohttpd should work well on GNU/Linux, BSD, OS X, W32 and z/OS.
+Note that HTTPS is not supported on z/OS (yet). We also have reports
+of users using it on vxWorks and Symbian. Note that on platforms
+where the compiler does not support the "constructor" attribute, you
+must call "MHD_init" before using any MHD functions and "MHD_fini"
+after you are done using MHD.
+
+
+Development Status
+==================
+
+This is a beta release for libmicrohttpd. Before declaring the
+library stable, we should implement support for HTTP "Upgrade"
+requests and have testcases for the following features:
+
+- HTTP/1.1 pipelining (need to figure out how to ensure curl pipelines
+ -- and it seems libcurl has issues with pipelining,
+ see http://curl.haxx.se/mail/lib-2007-12/0248.html)
+- resource limit enforcement
+- client queuing early response, suppressing 100 CONTINUE
+- chunked encoding to validate handling of footers
+- more testing for SSL support
+- MHD basic and digest authentication
+
+In particular, the following functions are not covered by 'make check':
+- mhd_panic_std (daemon.c); special case (abort)
+- parse_options (daemon.c)
+- MHD_set_panic_func (daemon.c)
+- MHD_get_version (daemon.c)
+
+
+This is an early alpha release for libmicrospdy. The following things
+should be implemented (in order of importance) before we can claim to
+be reasonably complete:
+- 8 different output queues (one for each priority) have to be implemented
+together with a suitable algorithm for utilizing them. Otherwise, downloading
+a file will block all responses with same or smaller priority
+- SPDY RST_STREAM sending on each possible error (DONE?)
+- SPDY_close_session
+- Find the best way for closing still opened stream (new call or existing)
+- SPDY_is_stream_opened
+- SPDY PING (used often by browsers)
+- receiving SPDY WINDOW_UPDATE
+- SPDY Settings
+- SPDY PUSH
+- SPDY HEADERS
+- SPDY Credentials
+
+Additional ideas for features include:
+- Individual callbacks for each session
+- Individual timeout for each session
+
+Unimplemented API functions of libmicrospdy:
+- SPDY_settings_create ();
+- SPDY_settings_add (...);
+- SPDY_settings_lookup (...);
+- SPDY_settings_iterate (...);
+- SPDY_settings_destroy (...);
+- SPDY_close_session(...);
+- SPDY_send_ping(...);
+- SPDY_send_settings (...);
+
+In particular, we should write tests for:
+- Enqueueing responses while considering request priorities.
+- HTTP methods other than GET
+
+
+
+
+
+Missing documentation:
+======================
+
+- libmicrospdy manual:
+ * missing entirely

+# Of course, Automake must honor this variable whenever it calls a

+# depending on how configure is run. This is pretty annoying, since

+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.

+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+ --enable-spdy enable build libmicrospdy (yes, no, auto) [auto]
+ --disable-largefile omit support for large files
+ --disable-messages disable MHD error messages
+ --disable-postprocessor disable MHD PostProcessor functionality
+ --enable-https enable HTTPS support (yes, no, auto)[auto]
+ --disable-bauth disable HTTP basic Auth support
+ --disable-dauth disable HTTP basic and digest Auth support

+ --with-threads=LIB choose threading library (posix, w32, auto) [auto]
+ --with-libcurl=PREFIX look for the curl library in PREFIX/lib and headers
+ in PREFIX/include
+ --with-openssl=DIR root of the OpenSSL directory
+ --with-libgcrypt-prefix=PFX
+ prefix where LIBGCRYPT is installed (optional)
+ --with-gnutls[=PFX] use GnuTLS for HTTPS support, optional PFX overrides

+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+ PKG_CONFIG path to pkg-config utility
+ PKG_CONFIG_PATH
+ directories to add to pkg-config's search path
+ PKG_CONFIG_LIBDIR
+ path overriding pkg-config's built-in search path
+ GNUTLS_CFLAGS
+ C compiler flags for GNUTLS, overriding pkg-config
+ GNUTLS_LIBS linker flags for GNUTLS, overriding pkg-config
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+## dummy dependencies for each header file. Too bad gcc doesn't do
+## this for us directly.

+With the small exception of IP address based access control,
+requests from all connecting clients where served equally until now.
+This chapter discusses a first method of client's authentication and
+its limits.
+
+A very simple approach feasible with the means already discussed would
+be to expect the password in the @emph{URI} string before granting access to
+the secured areas. The password could be separated from the actual resource identifier
+by a certain character, thus the request line might look like
+@verbatim
+GET /picture.png?mypassword
+@end verbatim
+@noindent
+
+In the rare situation where the client is customized enough and the connection occurs
+through secured lines (e.g., a embedded device directly attached to another via wire)
+and where the ability to embedd a password in the URI or to pass on a URI with a
+password are desired, this can be a reasonable choice.
+
+But when it is assumed that the user connecting does so with an ordinary Internet browser,
+this implementation brings some problems about. For example, the URI including the password
+stays in the address field or at least in the history of the browser for anybody near enough to see.
+It will also be inconvenient to add the password manually to any new URI when the browser does
+not know how to compose this automatically.
+
+At least the convenience issue can be addressed by employing the simplest built-in password
+facilities of HTTP compliant browsers, hence we want to start there. It will however turn out
+to have still severe weaknesses in terms of security which need consideration.
+
+Before we will start implementing @emph{Basic Authentication} as described in @emph{RFC 2617},
+we should finally abandon the bad practice of responding every request the first time our callback
+is called for a given connection. This is becoming more important now because the client and
+the server will have to talk in a more bi-directional way than before to
+
+But how can we tell whether the callback has been called before for the particular connection?
+Initially, the pointer this parameter references is set by @emph{MHD} in the callback. But it will
+also be "remembered" on the next call (for the same connection).
+Thus, we will generate no response until the parameter is non-null---implying the callback was
+called before at least once. We do not need to share information between different calls of the callback,
+so we can set the parameter to any adress that is assured to be not null. The pointer to the
+@code{connection} structure will be pointing to a legal address, so we take this.
+
+The first time @code{answer_to_connection} is called, we will not even look at the headers.
+
+@verbatim
+static int
+answer_to_connection (void *cls, struct MHD_Connection *connection,
+ const char *url, const char *method, const char *version,
+ const char *upload_data, size_t *upload_data_size,
+ void **con_cls)
+{
+ if (0 != strcmp(method, "GET")) return MHD_NO;
+ if (NULL == *con_cls) {*con_cls = connection; return MHD_YES;}
+
+ ...
+ /* else respond accordingly */
+ ...
+}
+@end verbatim
+@noindent
+
+Note how we lop off the connection on the first condition (no "GET" request), but return asking for more on
+the other one with @code{MHD_YES}.
+With this minor change, we can proceed to implement the actual authentication process.
+
+@heading Request for authentication
+
+Let us assume we had only files not intended to be handed out without the correct username/password,
+so every "GET" request will be challenged.
+@emph{RFC 2617} describes how the server shall ask for authentication by adding a
+@emph{WWW-Authenticate} response header with the name of the @emph{realm} protected.
+MHD can generate and queue such a failure response for you using
+the @code{MHD_queue_basic_auth_fail_response} API. The only thing you need to do
+is construct a response with the error page to be shown to the user
+if he aborts basic authentication. But first, you should check if the
+proper credentials were already supplied using the
+@code{MHD_basic_auth_get_username_password} call.
+
+Your code would then look like this:
+@verbatim
+static int
+answer_to_connection (void *cls, struct MHD_Connection *connection,
+ const char *url, const char *method,
+ const char *version, const char *upload_data,
+ size_t *upload_data_size, void **con_cls)
+{
+ char *user;
+ char *pass;
+ int fail;
+ struct MHD_Response *response;
+
+ if (0 != strcmp (method, MHD_HTTP_METHOD_GET))
+ return MHD_NO;
+ if (NULL == *con_cls)
+ {
+ *con_cls = connection;
+ return MHD_YES;
+ }
+ pass = NULL;
+ user = MHD_basic_auth_get_username_password (connection, &pass);
+ fail = ( (user == NULL) ||
+ (0 != strcmp (user, "root")) ||
+ (0 != strcmp (pass, "pa$$w0rd") ) );
+ if (user != NULL) free (user);
+ if (pass != NULL) free (pass);
+ if (fail)
+ {
+ const char *page = "<html><body>Go away.</body></html>";
+ response =
+ MHD_create_response_from_buffer (strlen (page), (void *) page,
+ MHD_RESPMEM_PERSISTENT);
+ ret = MHD_queue_basic_auth_fail_response (connection,
+ "my realm",
+ response);
+ }
+ else
+ {
+ const char *page = "<html><body>A secret.</body></html>";
+ response =
+ MHD_create_response_from_buffer (strlen (page), (void *) page,
+ MHD_RESPMEM_PERSISTENT);
+ ret = MHD_queue_response (connection, MHD_HTTP_OK, response);
+ }
+ MHD_destroy_response (response);
+ return ret;
+}
+@end verbatim
+
+See the @code{examples} directory for the complete example file.
+
+@heading Remarks
+For a proper server, the conditional statements leading to a return of @code{MHD_NO} should yield a
+response with a more precise status code instead of silently closing the connection. For example,
+failures of memory allocation are best reported as @emph{internal server error} and unexpected
+authentication methods as @emph{400 bad request}.
+
+@heading Exercises
+@itemize @bullet
+@item
+Make the server respond to wrong credentials (but otherwise well-formed requests) with the recommended
+@emph{401 unauthorized} status code. If the client still does not authenticate correctly within the
+same connection, close it and store the client's IP address for a certain time. (It is OK to check for
+expiration not until the main thread wakes up again on the next connection.) If the client fails
+authenticating three times during this period, add it to another list for which the
+@code{AcceptPolicyCallback} function denies connection (temporally).
+
+@item
+With the network utility @code{netcat} connect and log the response of a "GET" request as you
+did in the exercise of the first example, this time to a file. Now stop the server and let @emph{netcat}
+listen on the same port the server used to listen on and have it fake being the proper server by giving
+the file's content as the response (e.g. @code{cat log | nc -l -p 8888}). Pretending to think your were
+connecting to the actual server, browse to the eavesdropper and give the correct credentials.
+
+Copy and paste the encoded string you see in @code{netcat}'s output to some of the Base64 decode tools available online
+and see how both the user's name and password could be completely restored.

+This chapter will deal with the information which the client sends to the
+server at every request. We are going to examine the most useful fields of such an request
+and print them out in a readable manner. This could be useful for logging facilities.
+
+The starting point is the @emph{hellobrowser} program with the former response removed.
+
+This time, we just want to collect information in the callback function, thus we will
+just return MHD_NO after we have probed the request. This way, the connection is closed
+without much ado by the server.
+
+@verbatim
+static int
+answer_to_connection (void *cls, struct MHD_Connection *connection,
+ const char *url,
+ const char *method, const char *version,
+ const char *upload_data,
+ size_t *upload_data_size, void **con_cls)
+{
+ ...
+ return MHD_NO;
+}
+@end verbatim
+@noindent
+The ellipsis marks the position where the following instructions shall be inserted.
+
+
+We begin with the most obvious information available to the server, the request line. You should
+already have noted that a request consists of a command (or "HTTP method") and a URI (e.g. a filename).
+It also contains a string for the version of the protocol which can be found in @code{version}.
+To call it a "new request" is justified because we return only @code{MHD_NO}, thus ensuring the
+function will not be called again for this connection.
+@verbatim
+printf ("New %s request for %s using version %s\n", method, url, version);
+@end verbatim
+@noindent
+
+The rest of the information is a bit more hidden. Nevertheless, there is lot of it sent from common
+Internet browsers. It is stored in "key-value" pairs and we want to list what we find in the header.
+As there is no mandatory set of keys a client has to send, each key-value pair is printed out one by
+one until there are no more left. We do this by writing a separate function which will be called for
+each pair just like the above function is called for each HTTP request.
+It can then print out the content of this pair.
+@verbatim
+int print_out_key (void *cls, enum MHD_ValueKind kind,
+ const char *key, const char *value)
+{
+ printf ("%s: %s\n", key, value);
+ return MHD_YES;
+}
+@end verbatim
+@noindent
+
+To start the iteration process that calls our new function for every key, the line
+@verbatim
+MHD_get_connection_values (connection, MHD_HEADER_KIND, &print_out_key, NULL);
+@end verbatim
+@noindent
+needs to be inserted in the connection callback function too. The second parameter tells the function
+that we are only interested in keys from the general HTTP header of the request. Our iterating
+function @code{print_out_key} does not rely on any additional information to fulfill its duties
+so the last parameter can be NULL.
+
+All in all, this constitutes the complete @code{logging.c} program for this chapter which can be
+found in the @code{examples} section.
+
+Connecting with any modern Internet browser should yield a handful of keys. You should try to
+interpret them with the aid of @emph{RFC 2616}.
+Especially worth mentioning is the "Host" key which is often used to serve several different websites
+hosted under one single IP address but reachable by different domain names (this is called virtual hosting).
+
+@heading Conclusion
+The introduced capabilities to itemize the content of a simple GET request---especially the
+URI---should already allow the server to satisfy clients' requests for small specific resources
+(e.g. files) or even induce alteration of server state. However, the latter is not
+recommended as the GET method (including its header data) is by convention considered a "safe"
+operation, which should not change the server's state in a significant way. By convention,
+GET operations can thus be performed by crawlers and other automatic software. Naturally
+actions like searching for a passed string are fine.
+
+Of course, no transmission can occur while the return value is still set to @code{MHD_NO} in the
+callback function.
+
+@heading Exercises
+@itemize @bullet
+@item
+By parsing the @code{url} string and delivering responses accordingly, implement a small server for
+"virtual" files. When asked for @code{/index.htm@{l@}}, let the response consist of a HTML page
+containing a link to @code{/another.html} page which is also to be created "on the fly" in case of
+being requested. If neither of these two pages are requested, @code{MHD_HTTP_NOT_FOUND} shall be
+returned accompanied by an informative message.
+
+@item
+A very interesting information has still been ignored by our logger---the client's IP address.
+Implement a callback function
+@verbatim
+static int on_client_connect (void *cls,
+ const struct sockaddr *addr,
+ socklen_t addrlen)
+@end verbatim
+@noindent
+that prints out the IP address in an appropriate format. You might want to use the POSIX function
+@code{inet_ntoa} but bear in mind that @code{addr} is actually just a structure containing other
+substructures and is @emph{not} the variable this function expects.
+Make sure to return @code{MHD_YES} so that the library knows the client is allowed to connect
+(and to then process the request). If one wanted to limit access basing on IP addresses, this would be the place
+to do it. The address of your @code{on_client_connect} function must be passed as the third parameter to the
+@code{MHD_start_daemon} call.

+The most basic task for a HTTP server is to deliver a static text message to any client connecting to it.
+Given that this is also easy to implement, it is an excellent problem to start with.
+
+For now, the particular URI the client asks for shall have no effect on the message that will
+be returned. In addition, the server shall end the connection after the message has been sent so that
+the client will know there is nothing more to expect.
+
+The C program @code{hellobrowser.c}, which is to be found in the examples section, does just that.
+If you are very eager, you can compile and start it right away but it is advisable to type the
+lines in by yourself as they will be discussed and explained in detail.
+
+After the necessary includes and the definition of the port which our server should listen on
+@verbatim
+#include <sys/types.h>
+#include <sys/select.h>
+#include <sys/socket.h>
+#include <microhttpd.h>
+
+#define PORT 8888
+
+@end verbatim
+
+@noindent
+the desired behaviour of our server when HTTP request arrive has to be implemented. We already have
+agreed that it should not care about the particular details of the request, such as who is requesting
+what. The server will respond merely with the same small HTML page to every request.
+
+The function we are going to write now will be called by @emph{GNU libmicrohttpd} every time an
+appropriate request comes in. While the name of this callback function is arbitrary, its parameter
+list has to follow a certain layout. So please, ignore the lot of parameters for now, they will be
+explained at the point they are needed. We have to use only one of them,
+@code{struct MHD_Connection *connection}, for the minimalistic functionality we want to archive at the moment.
+
+This parameter is set by the @emph{libmicrohttpd} daemon and holds the necessary information to
+relate the call with a certain connection. Keep in mind that a server might have to satisfy hundreds
+of concurrent connections and we have to make sure that the correct data is sent to the destined
+client. Therefore, this variable is a means to refer to a particular connection if we ask the
+daemon to sent the reply.
+
+Talking about the reply, it is defined as a string right after the function header
+@verbatim
+int answer_to_connection (void *cls, struct MHD_Connection *connection,
+ const char *url,
+ const char *method, const char *version,
+ const char *upload_data,
+ size_t *upload_data_size, void **con_cls)
+{
+ const char *page = "<html><body>Hello, browser!</body></html>";
+
+@end verbatim
+
+@noindent
+HTTP is a rather strict protocol and the client would certainly consider it "inappropriate" if we
+just sent the answer string "as is". Instead, it has to be wrapped with additional information stored in so-called headers and footers. Most of the work in this area is done by the library for us---we
+just have to ask. Our reply string packed in the necessary layers will be called a "response".
+To obtain such a response we hand our data (the reply--string) and its size over to the
+@code{MHD_create_response_from_buffer} function. The last two parameters basically tell @emph{MHD}
+that we do not want it to dispose the message data for us when it has been sent and there also needs
+no internal copy to be done because the @emph{constant} string won't change anyway.
+
+@verbatim
+ struct MHD_Response *response;
+ int ret;
+
+ response = MHD_create_response_from_buffer (strlen (page),
+ (void*) page, MHD_RESPMEM_PERSISTENT);
+
+@end verbatim
+
+@noindent
+Now that the the response has been laced up, it is ready for delivery and can be queued for sending.
+This is done by passing it to another @emph{GNU libmicrohttpd} function. As all our work was done in
+the scope of one function, the recipient is without doubt the one associated with the
+local variable @code{connection} and consequently this variable is given to the queue function.
+Every HTTP response is accompanied by a status code, here "OK", so that the client knows
+this response is the intended result of his request and not due to some error or malfunction.
+
+Finally, the packet is destroyed and the return value from the queue returned,
+already being set at this point to either MHD_YES or MHD_NO in case of success or failure.
+
+@verbatim
+ ret = MHD_queue_response (connection, MHD_HTTP_OK, response);
+ MHD_destroy_response (response);
+
+ return ret;
+}
+
+@end verbatim
+
+@noindent
+With the primary task of our server implemented, we can start the actual server daemon which will listen
+on @code{PORT} for connections. This is done in the main function.
+@verbatim
+int main ()
+{
+ struct MHD_Daemon *daemon;
+
+ daemon = MHD_start_daemon (MHD_USE_SELECT_INTERNALLY, PORT, NULL, NULL,
+ &answer_to_connection, NULL, MHD_OPTION_END);
+ if (NULL == daemon) return 1;
+
+@end verbatim
+
+@noindent
+The first parameter is one of three possible modes of operation. Here we want the daemon to run in
+a separate thread and to manage all incoming connections in the same thread. This means that while
+producing the response for one connection, the other connections will be put on hold. In this
+example, where the reply is already known and therefore the request is served quickly, this poses no problem.
+
+We will allow all clients to connect regardless of their name or location, therefore we do not check
+them on connection and set the forth and fifth parameter to NULL.
+
+Parameter six is the address of the function we want to be called whenever a new connection has been
+established. Our @code{answer_to_connection} knows best what the client wants and needs no additional
+information (which could be passed via the next parameter) so the next parameter is NULL. Likewise,
+we do not need to pass extra options to the daemon so we just write the MHD_OPTION_END as the last parameter.
+
+As the server daemon runs in the background in its own thread, the execution flow in our main
+function will contine right after the call. Because of this, we must delay the execution flow in the
+main thread or else the program will terminate prematurely. We let it pause in a processing-time
+friendly manner by waiting for the enter key to be pressed. In the end, we stop the daemon so it can
+do its cleanup tasks.
+@verbatim
+ getchar ();
+
+ MHD_stop_daemon (daemon);
+ return 0;
+}
+
+@end verbatim
+
+@noindent
+The first example is now complete.
+
+Compile it with
+@verbatim
+cc hellobrowser.c -o hellobrowser -I$PATH_TO_LIBMHD_INCLUDES
+ -L$PATH_TO_LIBMHD_LIBS -lmicrohttpd
+@end verbatim
+with the two paths set accordingly and run it.
+
+Now open your favorite Internet browser and go to the address @code{http://localhost:8888/}, provided that 8888
+is the port you chose. If everything works as expected, the browser will present the message of the
+static HTML page it got from our minimal server.
+
+@heading Remarks
+To keep this first example as small as possible, some drastic shortcuts were taken and are to be
+discussed now.
+
+Firstly, there is no distinction made between the kinds of requests a client could send. We implied
+that the client sends a GET request, that means, that he actually asked for some data. Even when
+it is not intended to accept POST requests, a good server should at least recognize that this
+request does not constitute a legal request and answer with an error code. This can be easily
+implemented by checking if the parameter @code{method} equals the string "GET" and returning a
+@code{MHD_NO} if not so.
+
+Secondly, the above practice of queuing a response upon the first call of the callback function
+brings with it some limitations. This is because the content of the message body will not be
+received if a response is queued in the first iteration. Furthermore, the connection will be closed
+right after the response has been transferred then. This is typically not what you want as it
+disables HTTP pipelining. The correct approach is to simply not queue a message on the first
+callback unless there is an error. The @code{void**} argument to the callback provides a location
+for storing information about the history of the connection; for the first call, the pointer
+will point to NULL. A simplistic way to differenciate the first call from others is to check
+if the pointer is NULL and set it to a non-NULL value during the first call.
+
+Both of these issues you will find addressed in the official @code{minimal_example.c} residing in
+the @code{src/examples} directory of the @emph{MHD} package. The source code of this
+program should look very familiar to you by now and easy to understand.
+
+For our example, the @code{must_copy} and @code{must_free} parameter at the response construction
+function could be set to @code{MHD_NO}. In the usual case, responses cannot be sent immediately
+after being queued. For example, there might be other data on the system that needs to be sent with
+a higher priority. Nevertheless, the queue function will return successfully---raising the problem
+that the data we have pointed to may be invalid by the time it is about being sent. This is not an
+issue here because we can expect the @code{page} string, which is a constant @emph{string literal}
+here, to be static. That means it will be present and unchanged for as long as the program runs.
+For dynamic data, one could choose to either have @emph{MHD} free the memory @code{page} points
+to itself when it is not longer needed or, alternatively, have the library to make and manage
+its own copy of it.
+
+@heading Exercises
+@itemize @bullet
+@item
+While the server is running, use a program like @code{telnet} or @code{netcat} to connect to it. Try to form a
+valid HTTP 1.1 request yourself like
+@verbatim
+GET /dontcare HTTP/1.1
+Host: itsme
+<enter>
+@end verbatim
+@noindent
+and see what the server returns to you.
+
+
+@item
+Also, try other requests, like POST, and see how our server does not mind and why.
+How far in malforming a request can you go before the builtin functionality of @emph{MHD} intervenes
+and an altered response is sent? Make sure you read about the status codes in the @emph{RFC}.
+
+
+@item
+Add the option @code{MHD_USE_PEDANTIC_CHECKS} to the start function of the daemon in @code{main}.
+Mind the special format of the parameter list here which is described in the manual. How indulgent
+is the server now to your input?
+
+
+@item
+Let the main function take a string as the first command line argument and pass @code{argv[1]} to
+the @code{MHD_start_daemon} function as the sixth parameter. The address of this string will be
+passed to the callback function via the @code{cls} variable. Decorate the text given at the command
+line when the server is started with proper HTML tags and send it as the response instead of the
+former static string.
+
+
+@item
+@emph{Demanding:} Write a separate function returning a string containing some useful information,
+for example, the time. Pass the function's address as the sixth parameter and evaluate this function
+on every request anew in @code{answer_to_connection}. Remember to free the memory of the string
+every time after satisfying the request.

+The previous chapter introduced a way to upload data to the server, but the developed example program
+has some shortcomings, such as not being able to handle larger chunks of data. In this chapter, we
+are going to discuss a more advanced server program that allows clients to upload a file in order to
+have it stored on the server's filesystem. The server shall also watch and limit the number of
+clients concurrently uploading, responding with a proper busy message if necessary.
+
+
+@heading Prepared answers
+We choose to operate the server with the @code{SELECT_INTERNALLY} method. This makes it easier to
+synchronize the global states at the cost of possible delays for other connections if the processing
+of a request is too slow. One of these variables that needs to be shared for all connections is the
+total number of clients that are uploading.
+
+@verbatim
+#define MAXCLIENTS 2
+static unsigned int nr_of_uploading_clients = 0;

+If there are too many clients uploading, we want the server to respond to all requests with a busy
+message.
+@verbatim
+const char* busypage =
+ "<html><body>This server is busy, please try again later.</body></html>";
+@end verbatim
+@noindent
+
+Otherwise, the server will send a @emph{form} that informs the user of the current number of uploading clients,
+and ask her to pick a file on her local filesystem which is to be uploaded.

+If the upload has succeeded, the server will respond with a message saying so.
+@verbatim
+const char* completepage = "<html><body>The upload has been completed.</body></html>";
+@end verbatim
+@noindent
+
+We want the server to report internal errors, such as memory shortage or file access problems,
+adequately.
+@verbatim
+const char* servererrorpage
+ = "<html><body>An internal server error has occured.</body></html>";
+const char* fileexistspage
+ = "<html><body>This file already exists.</body></html>";
+@end verbatim
+@noindent
+
+It would be tolerable to send all these responses undifferentiated with a @code{200 HTTP_OK}
+status code but in order to improve the @code{HTTP} conformance of our server a bit, we extend the
+@code{send_page} function so that it accepts individual status codes.
+
+@verbatim
+static int
+send_page (struct MHD_Connection *connection,
+ const char* page, int status_code)
+{
+ int ret;
+ struct MHD_Response *response;
+
+ response = MHD_create_response_from_buffer (strlen (page), (void*) page,
+ MHD_RESPMEM_MUST_COPY);
+ if (!response) return MHD_NO;
+
+ ret = MHD_queue_response (connection, status_code, response);
+ MHD_destroy_response (response);
+
+ return ret;
+}
+@end verbatim
+@noindent
+
+Note how we ask @emph{MHD} to make its own copy of the message data. The reason behind this will
+become clear later.
+
+
+@heading Connection cycle
+The decision whether the server is busy or not is made right at the beginning of the connection. To
+do that at this stage is especially important for @emph{POST} requests because if no response is
+queued at this point, and @code{MHD_YES} returned, @emph{MHD} will not sent any queued messages until
+a postprocessor has been created and the post iterator is called at least once.
+
+@verbatim
+static int
+answer_to_connection (void *cls, struct MHD_Connection *connection,
+ const char *url,
+ const char *method, const char *version,
+ const char *upload_data,
+ size_t *upload_data_size, void **con_cls)
+{
+ if (NULL == *con_cls)
+ {
+ struct connection_info_struct *con_info;
+
+ if (nr_of_uploading_clients >= MAXCLIENTS)
+ return send_page(connection, busypage, MHD_HTTP_SERVICE_UNAVAILABLE);
+@end verbatim
+@noindent
+
+If the server is not busy, the @code{connection_info} structure is initialized as usual, with
+the addition of a filepointer for each connection.
+
+@verbatim
+ con_info = malloc (sizeof (struct connection_info_struct));
+ if (NULL == con_info) return MHD_NO;
+ con_info->fp = 0;
+
+ if (0 == strcmp (method, "POST"))
+ {
+ ...
+ }
+ else con_info->connectiontype = GET;
+
+ *con_cls = (void*) con_info;
+
+ return MHD_YES;
+ }
+@end verbatim
+@noindent
+
+For @emph{POST} requests, the postprocessor is created and we register a new uploading client. From
+this point on, there are many possible places for errors to occur that make it necessary to interrupt
+the uploading process. We need a means of having the proper response message ready at all times.
+Therefore, the @code{connection_info} structure is extended to hold the most current response
+message so that whenever a response is sent, the client will get the most informative message. Here,
+the structure is initialized to "no error".
+@verbatim
+ if (0 == strcmp (method, "POST"))
+ {
+ con_info->postprocessor
+ = MHD_create_post_processor (connection, POSTBUFFERSIZE,
+ iterate_post, (void*) con_info);
+
+ if (NULL == con_info->postprocessor)
+ {
+ free (con_info);
+ return MHD_NO;
+ }
+
+ nr_of_uploading_clients++;
+
+ con_info->connectiontype = POST;
+ con_info->answercode = MHD_HTTP_OK;
+ con_info->answerstring = completepage;
+ }
+ else con_info->connectiontype = GET;
+@end verbatim
+@noindent
+
+If the connection handler is called for the second time, @emph{GET} requests will be answered with
+the @emph{form}. We can keep the buffer under function scope, because we asked @emph{MHD} to make its
+own copy of it for as long as it is needed.
+@verbatim
+ if (0 == strcmp (method, "GET"))
+ {
+ int ret;
+ char buffer[1024];
+
+ sprintf (buffer, askpage, nr_of_uploading_clients);
+ return send_page (connection, buffer, MHD_HTTP_OK);
+ }
+@end verbatim
+@noindent
+
+
+The rest of the @code{answer_to_connection} function is very similar to the @code{simplepost.c}
+example, except the more flexible content of the responses. The @emph{POST} data is processed until
+there is none left and the execution falls through to return an error page if the connection
+constituted no expected request method.
+@verbatim
+ if (0 == strcmp (method, "POST"))
+ {
+ struct connection_info_struct *con_info = *con_cls;
+
+ if (0 != *upload_data_size)
+ {
+ MHD_post_process (con_info->postprocessor,
+ upload_data, *upload_data_size);
+ *upload_data_size = 0;
+
+ return MHD_YES;
+ }
+ else
+ return send_page (connection, con_info->answerstring,
+ con_info->answercode);
+ }
+
+ return send_page(connection, errorpage, MHD_HTTP_BAD_REQUEST);
+}
+@end verbatim
+@noindent
+
+
+@heading Storing to data
+Unlike the @code{simplepost.c} example, here it is to be expected that post iterator will be called
+several times now. This means that for any given connection (there might be several concurrent of them)
+the posted data has to be written to the correct file. That is why we store a file handle in every
+@code{connection_info}, so that the it is preserved between successive iterations.
+@verbatim
+static int
+iterate_post (void *coninfo_cls, enum MHD_ValueKind kind,
+ const char *key,
+ const char *filename, const char *content_type,
+ const char *transfer_encoding, const char *data,
+ uint64_t off, size_t size)
+{
+ struct connection_info_struct *con_info = coninfo_cls;
+@end verbatim
+@noindent
+
+Because the following actions depend heavily on correct file processing, which might be error prone,
+we default to reporting internal errors in case anything will go wrong.
+
+@verbatim
+con_info->answerstring = servererrorpage;
+con_info->answercode = MHD_HTTP_INTERNAL_SERVER_ERROR;
+@end verbatim
+@noindent
+
+In the "askpage" @emph{form}, we told the client to label its post data with the "file" key. Anything else
+would be an error.
+
+@verbatim
+ if (0 != strcmp (key, "file")) return MHD_NO;
+@end verbatim
+@noindent
+
+If the iterator is called for the first time, no file will have been opened yet. The @code{filename}
+string contains the name of the file (without any paths) the user selected on his system. We want to
+take this as the name the file will be stored on the server and make sure no file of that name exists
+(or is being uploaded) before we create one (note that the code below technically contains a
+race between the two "fopen" calls, but we will overlook this for portability sake).
+@verbatim
+ if (!con_info->fp)
+ {
+ if (NULL != (fp = fopen (filename, "rb")) )
+ {
+ fclose (fp);
+ con_info->answerstring = fileexistspage;
+ con_info->answercode = MHD_HTTP_FORBIDDEN;
+ return MHD_NO;
+ }
+
+ con_info->fp = fopen (filename, "ab");
+ if (!con_info->fp) return MHD_NO;
+ }
+@end verbatim
+@noindent
+
+
+Occasionally, the iterator function will be called even when there are 0 new bytes to process. The
+server only needs to write data to the file if there is some.
+@verbatim
+if (size > 0)
+ {
+ if (!fwrite (data, size, sizeof(char), con_info->fp))
+ return MHD_NO;
+ }
+@end verbatim
+@noindent
+
+If this point has been reached, everything worked well for this iteration and the response can
+be set to success again. If the upload has finished, this iterator function will not be called again.
+@verbatim
+ con_info->answerstring = completepage;
+ con_info->answercode = MHD_HTTP_OK;
+
+ return MHD_YES;
+}
+@end verbatim
+@noindent
+
+
+The new client was registered when the postprocessor was created. Likewise, we unregister the client
+on destroying the postprocessor when the request is completed.
+@verbatim
+void request_completed (void *cls, struct MHD_Connection *connection,
+ void **con_cls,
+ enum MHD_RequestTerminationCode toe)
+{
+ struct connection_info_struct *con_info = *con_cls;
+
+ if (NULL == con_info) return;
+
+ if (con_info->connectiontype == POST)
+ {
+ if (NULL != con_info->postprocessor)
+ {
+ MHD_destroy_post_processor (con_info->postprocessor);
+ nr_of_uploading_clients--;
+ }
+
+ if (con_info->fp) fclose (con_info->fp);
+ }
+
+ free (con_info);
+ *con_cls = NULL;
+}
+@end verbatim
+@noindent
+
+
+This is essentially the whole example @code{largepost.c}.
+
+
+@heading Remarks
+Now that the clients are able to create files on the server, security aspects are becoming even more
+important than before. Aside from proper client authentication, the server should always make sure
+explicitly that no files will be created outside of a dedicated upload directory. In particular,
+filenames must be checked to not contain strings like "../".

+The previous chapters already have demonstrated a variety of possibilities to send information
+to the HTTP server, but it is not recommended that the @emph{GET} method is used to alter the way
+the server operates. To induce changes on the server, the @emph{POST} method is preferred over
+and is much more powerful than @emph{GET} and will be introduced in this chapter.
+
+We are going to write an application that asks for the visitor's name and, after the user has posted it,
+composes an individual response text. Even though it was not mandatory to use the @emph{POST} method here,
+as there is no permanent change caused by the POST, it is an illustrative example on how to share data
+between different functions for the same connection. Furthermore, the reader should be able to extend
+it easily.
+
+@heading GET request
+When the first @emph{GET} request arrives, the server shall respond with a HTML page containing an
+edit field for the name.
+
+@verbatim
+const char* askpage = "<html><body>\
+ What's your name, Sir?<br>\
+ <form action=\"/namepost\" method=\"post\">\
+ <input name=\"name\" type=\"text\"\
+ <input type=\"submit\" value=\" Send \"></form>\
+ </body></html>";
+@end verbatim
+@noindent
+
+The @code{action} entry is the @emph{URI} to be called by the browser when posting, and the
+@code{name} will be used later to be sure it is the editbox's content that has been posted.
+
+We also prepare the answer page, where the name is to be filled in later, and an error page
+as the response for anything but proper @emph{GET} and @emph{POST} requests:
+
+@verbatim
+const char* greatingpage="<html><body><h1>Welcome, %s!</center></h1></body></html>";
+
+const char* errorpage="<html><body>This doesn't seem to be right.</body></html>";
+@end verbatim
+@noindent
+
+Whenever we need to send a page, we use an extra function
+@code{int send_page(struct MHD_Connection *connection, const char* page)}
+for this, which does not contain anything new and whose implementation is therefore
+not discussed further in the tutorial.
+
+
+@heading POST request
+Posted data can be of arbitrary and considerable size; for example, if a user uploads a big
+image to the server. Similar to the case of the header fields, there may also be different streams
+of posted data, such as one containing the text of an editbox and another the state of a button.
+Likewise, we will have to register an iterator function that is going to be called maybe several times
+not only if there are different POSTs but also if one POST has only been received partly yet and
+needs processing before another chunk can be received.
+
+Such an iterator function is called by a @emph{postprocessor}, which must be created upon arriving
+of the post request. We want the iterator function to read the first post data which is tagged
+@code{name} and to create an individual greeting string based on the template and the name.
+But in order to pass this string to other functions and still be able to differentiate different
+connections, we must first define a structure to share the information, holding the most import entries.
+
+@verbatim
+struct connection_info_struct
+{
+ int connectiontype;
+ char *answerstring;
+ struct MHD_PostProcessor *postprocessor;
+};
+@end verbatim
+@noindent
+
+With these information available to the iterator function, it is able to fulfill its task.
+Once it has composed the greeting string, it returns @code{MHD_NO} to inform the post processor
+that it does not need to be called again. Note that this function does not handle processing
+of data for the same @code{key}. If we were to expect that the name will be posted in several
+chunks, we had to expand the namestring dynamically as additional parts of it with the same @code{key}
+came in. But in this example, the name is assumed to fit entirely inside one single packet.
+
+@verbatim
+static int
+iterate_post (void *coninfo_cls, enum MHD_ValueKind kind, const char *key,
+ const char *filename, const char *content_type,
+ const char *transfer_encoding, const char *data,
+ uint64_t off, size_t size)

+ con_info->answerstring = answerstring;
+ }
+ else con_info->answerstring = NULL;
+
+ return MHD_NO;
+ }
+
+ return MHD_YES;
+}
+@end verbatim
+@noindent
+
+Once a connection has been established, it can be terminated for many reasons. As these
+reasons include unexpected events, we have to register another function that cleans up any resources
+that might have been allocated for that connection by us, namely the post processor and the greetings
+string. This cleanup function must take into account that it will also be called for finished
+requests other than @emph{POST} requests.
+
+@verbatim

+ MHD_OPTION_NOTIFY_COMPLETED, &request_completed, NULL,
+ MHD_OPTION_END);
+...
+@end verbatim
+@noindent
+
+@heading Request handling
+With all other functions prepared, we can now discuss the actual request handling.
+
+On the first iteration for a new request, we start by allocating a new instance of a
+@code{struct connection_info_struct} structure, which will store all necessary information for later
+iterations and other functions.
+
+@verbatim
+static int
+answer_to_connection (void *cls, struct MHD_Connection *connection,

+ if (NULL == con_info) return MHD_NO;
+ con_info->answerstring = NULL;
+@end verbatim
+@noindent
+
+If the new request is a @emph{POST}, the postprocessor must be created now. In addition, the type
+of the request is stored for convenience.
+@verbatim
+ if (0 == strcmp (method, "POST"))
+ {
+ con_info->postprocessor
+ = MHD_create_post_processor (connection, POSTBUFFERSIZE,
+ iterate_post, (void*) con_info);
+
+ if (NULL == con_info->postprocessor)
+ {
+ free (con_info);
+ return MHD_NO;
+ }
+ con_info->connectiontype = POST;
+ }
+ else con_info->connectiontype = GET;
+@end verbatim
+@noindent
+
+The address of our structure will both serve as the indicator for successive iterations and to remember
+the particular details about the connection.
+@verbatim
+ *con_cls = (void*) con_info;
+ return MHD_YES;
+ }
+@end verbatim
+@noindent
+
+The rest of the function will not be executed on the first iteration. A @emph{GET} request is easily
+satisfied by sending the question form.
+@verbatim
+ if (0 == strcmp (method, "GET"))
+ {
+ return send_page (connection, askpage);
+ }
+@end verbatim
+@noindent
+
+In case of @emph{POST}, we invoke the post processor for as long as data keeps incoming, setting
+@code{*upload_data_size} to zero in order to indicate that we have processed---or at least have
+considered---all of it.
+@verbatim
+ if (0 == strcmp (method, "POST"))
+ {
+ struct connection_info_struct *con_info = *con_cls;
+
+ if (*upload_data_size != 0)
+ {
+ MHD_post_process (con_info->postprocessor, upload_data,

+ return MHD_YES;
+ }
+ else if (NULL != con_info->answerstring)
+ return send_page (connection, con_info->answerstring);
+ }
+@end verbatim
+@noindent
+
+Finally, if they are neither @emph{GET} nor @emph{POST} requests, the error page is returned.
+@verbatim
+ return send_page(connection, errorpage);
+}
+@end verbatim

+
+These were the important parts of the program @code{simplepost.c}.

+Now that we are able to inspect the incoming request in great detail,
+this chapter discusses the means to enrich the outgoing responses likewise.
+
+As you have learned in the @emph{Hello, Browser} chapter, some obligatory
+header fields are added and set automatically for simple responses by the library
+itself but if more advanced features are desired, additional fields have to be created.
+One of the possible fields is the content type field and an example will be developed around it.
+This will lead to an application capable of correctly serving different types of files.
+
+
+When we responded with HTML page packed in the static string previously, the client had no choice
+but guessing about how to handle the response, because the server had not told him.
+What if we had sent a picture or a sound file? Would the message have been understood
+or merely been displayed as an endless stream of random characters in the browser?
+This is what the mime content types are for. The header of the response is extended
+by certain information about how the data is to be interpreted.
+
+To introduce the concept, a picture of the format @emph{PNG} will be sent to the client
+and labeled accordingly with @code{image/png}.
+Once again, we can base the new example on the @code{hellobrowser} program.
+

+@end verbatim
+@noindent
+
+We want the program to open the file for reading and determine its size:
+@verbatim
+ int fd;
+ int ret;
+ struct stat sbuf;
+
+ if (0 != strcmp (method, "GET"))
+ return MHD_NO;
+ if ( (-1 == (fd = open (FILENAME, O_RDONLY))) ||
+ (0 != fstat (fd, &sbuf)) )
+ {
+ /* error accessing file */
+ /* ... (see below) */
+ }
+ /* ... (see below) */
+@end verbatim
+@noindent
+
+When dealing with files, there is a lot that could go wrong on the
+server side and if so, the client should be informed with @code{MHD_HTTP_INTERNAL_SERVER_ERROR}.
+
+@verbatim
+ /* error accessing file */
+ if (fd != -1) close (fd);
+ const char *errorstr =
+ "<html><body>An internal server error has occured!\

+ MHD_HTTP_INTERNAL_SERVER_ERROR,

+ MHD_destroy_response (response);
+
+ return MHD_YES;
+ }
+ else return MHD_NO;
+ }
+@end verbatim
+@noindent
+
+Note that we nevertheless have to create a response object even for sending a simple error code.
+Otherwise, the connection would just be closed without comment, leaving the client curious about
+what has happened.
+
+But in the case of success a response will be constructed directly from the file descriptor:
+
+@verbatim
+ /* error accessing file */
+ /* ... (see above) */
+ }
+
+ response =
+ MHD_create_response_from_fd_at_offset (sbuf.st_size, fd, 0);
+ MHD_add_response_header (response, "Content-Type", MIMETYPE);
+ ret = MHD_queue_response (connection, MHD_HTTP_OK, response);
+ MHD_destroy_response (response);
+@end verbatim
+@noindent
+
+Note that the response object will take care of closing the file desciptor for us.
+
+Up to this point, there was little new. The actual novelty is that we enhance the header with the
+meta data about the content. Aware of the field's name we want to add, it is as easy as that:
+@verbatim
+MHD_add_response_header(response, "Content-Type", MIMETYPE);
+@end verbatim
+@noindent
+We do not have to append a colon expected by the protocol behind the first
+field---@emph{GNU libhttpdmicro} will take care of this.
+
+The function finishes with the well-known lines
+@verbatim
+ ret = MHD_queue_response (connection, MHD_HTTP_OK, response);
+ MHD_destroy_response (response);
+ return ret;
+}
+@end verbatim
+@noindent
+
+The complete program @code{responseheaders.c} is in the @code{examples} section as usual.
+Find a @emph{PNG} file you like and save it to the directory the example is run from under the name
+@code{picture.png}. You should find the image displayed on your browser if everything worked well.
+
+@heading Remarks
+The include file of the @emph{MHD} library comes with the header types mentioned in @emph{RFC 2616}
+already defined as macros. Thus, we could have written @code{MHD_HTTP_HEADER_CONTENT_TYPE} instead
+of @code{"Content-Type"} as well. However, one is not limited to these standard headers and could
+add custom response headers without violating the protocol. Whether, and how, the client would react
+to these custom header is up to the receiver. Likewise, the client is allowed to send custom request
+headers to the server as well, opening up yet more possibilities how client and server could
+communicate with each other.
+
+The method of creating the response from a file on disk only works for static content.
+Serving dynamically created responses will be a topic of a future chapter.
+
+@heading Exercises
+@itemize @bullet
+
+@item
+Remember that the original program was written under a few assumptions---a static response
+using a local file being one of them. In order to simulate a very large or hard to reach file that cannot be provided
+instantly, postpone the queuing in the callback with the @code{sleep} function for 30 seconds
+@emph{if} the file @code{/big.png} is requested (but deliver the same as above). A request for
+@code{/picture.png} should provide just the same but without any artificial delays.
+
+Now start two instances of your browser (or even use two machines) and see how the second client
+is put on hold while the first waits for his request on the slow file to be fulfilled.
+
+Finally, change the sourcecode to use @code{MHD_USE_THREAD_PER_CONNECTION} when the daemon is
+started and try again.
+
+
+@item
+Did you succeed in implementing the clock exercise yet? This time, let the server save the
+program's start time @code{t} and implement a response simulating a countdown that reaches 0 at
+@code{t+60}. Returning a message saying on which point the countdown is, the response should
+ultimately be to reply "Done" if the program has been running long enough,
+
+An unofficial, but widely understood, response header line is @code{Refresh: DELAY; url=URL} with
+the uppercase words substituted to tell the client it should request the given resource after
+the given delay again. Improve your program in that the browser (any modern browser should work)
+automatically reconnects and asks for the status again every 5 seconds or so. The URL would have
+to be composed so that it begins with "http://", followed by the @emph{URI} the server is reachable
+from the client's point of view.
+
+Maybe you want also to visualize the countdown as a status bar by creating a
+@code{<table>} consisting of one row and @code{n} columns whose fields contain small images of either
+a red or a green light.

+HTTP requests from the same user. We use a simple example where the user submits multiple
+forms and the server is supposed to accumulate state from all of these forms. Naturally, as
+this is a network protocol, our session mechanism must support having many users with
+many concurrent sessions at the same time.
+
+In order to track users, we use a simple session cookie. A session cookie expires when the
+user closes the browser. Changing from session cookies to persistent cookies only requires
+adding an expiration time to the cookie. The server creates a fresh session cookie whenever
+a request without a cookie is received, or if the supplied session cookie is not known to
+the server.
+
+@heading Looking up the cookie
+
+Since MHD parses the HTTP cookie header for us, looking up an existing cookie
+is straightforward:
+
+@verbatim
+FIXME.
+@end verbatim
+
+Here, FIXME is the name we chose for our session cookie.
+
+
+@heading Setting the cookie header
+
+MHD requires the user to provide the full cookie format string in order to set
+cookies. In order to generate a unique cookie, our example creates a random
+64-character text string to be used as the value of the cookie:
+
+@verbatim
+FIXME.
+@end verbatim
+
+Given this cookie value, we can then set the cookie header in our HTTP response
+as follows:
+
+@verbatim
+FIXME.
+@end verbatim
+
+
+@heading Remark: Session expiration
+
+It is of course possible that clients stop their interaction with the
+server at any time. In order to avoid using too much storage, the
+server must thus discard inactive sessions at some point. Our example
+implements this by discarding inactive sessions after a certain amount
+of time. Alternatively, the implementation may limit the total number
+of active sessions. Which bounds are used for idle sessions or the
+total number of sessions obviously depends largely on the type of
+the application and available server resources.
+
+@heading Example code
+
+A sample application implementing a website with multiple
+forms (which are dynamically created using values from previous
+POST requests from the same session) is available
+as the example @code{sessions.c}.
+
+Note that the example uses a simple, $O(n)$ linked list traversal to
+look up sessions and to expire old sessions. Using a hash table and a
+heap would be more appropriate if a large number of concurrent
+sessions is expected.
+
+@heading Remarks
+
+Naturally, it is quite conceivable to store session data in a database
+instead of in memory. Still, having mechanisms to expire data
+associated with long-time idle sessions (where the business process
+has still not finished) is likely a good idea.

+We left the basic authentication chapter with the unsatisfactory conclusion that
+any traffic, including the credentials, could be intercepted by anyone between
+the browser client and the server. Protecting the data while it is sent over
+unsecured lines will be the goal of this chapter.
+
+Since version 0.4, the @emph{MHD} library includes support for encrypting the
+traffic by employing SSL/TSL. If @emph{GNU libmicrohttpd} has been configured to
+support these, encryption and decryption can be applied transparently on the
+data being sent, with only minimal changes to the actual source code of the example.
+
+
+@heading Preparation
+
+First, a private key for the server will be generated. With this key, the server
+will later be able to authenticate itself to the client---preventing anyone else
+from stealing the password by faking its identity. The @emph{OpenSSL} suite, which
+is available on many operating systems, can generate such a key. For the scope of
+this tutorial, we will be content with a 1024 bit key:
+@verbatim
+> openssl genrsa -out server.key 1024
+@end verbatim
+@noindent
+
+In addition to the key, a certificate describing the server in human readable tokens
+is also needed. This certificate will be attested with our aforementioned key. In this way,
+we obtain a self-signed certificate, valid for one year.
+
+@verbatim
+> openssl req -days 365 -out server.pem -new -x509 -key server.key
+@end verbatim
+@noindent
+
+To avoid unnecessary error messages in the browser, the certificate needs to
+have a name that matches the @emph{URI}, for example, "localhost" or the domain.
+If you plan to have a publicly reachable server, you will need to ask a trusted third party,
+called @emph{Certificate Authority}, or @emph{CA}, to attest the certificate for you. This way,
+any visitor can make sure the server's identity is real.
+
+Whether the server's certificate is signed by us or a third party, once it has been accepted
+by the client, both sides will be communicating over encrypted channels. From this point on,
+it is the client's turn to authenticate itself. But this has already been implemented in the basic
+authentication scheme.
+
+
+@heading Changing the source code
+
+We merely have to extend the server program so that it loads the two files into memory,
+
+@verbatim
+int
+main ()
+{
+ struct MHD_Daemon *daemon;
+ char *key_pem;
+ char *cert_pem;
+
+ key_pem = load_file (SERVERKEYFILE);
+ cert_pem = load_file (SERVERCERTFILE);
+
+ if ((key_pem == NULL) || (cert_pem == NULL))
+ {
+ printf ("The key/certificate files could not be read.\n");
+ return 1;
+ }
+@end verbatim
+@noindent
+
+and then we point the @emph{MHD} daemon to it upon initalization.
+@verbatim
+
+ daemon = MHD_start_daemon (MHD_USE_SELECT_INTERNALLY | MHD_USE_SSL,
+ PORT, NULL, NULL,
+ &answer_to_connection, NULL,
+ MHD_OPTION_HTTPS_MEM_KEY, key_pem,
+ MHD_OPTION_HTTPS_MEM_CERT, cert_pem,
+ MHD_OPTION_END);
+
+ if (NULL == daemon)
+ {
+ printf ("%s\n", cert_pem);
+
+ free (key_pem);
+ free (cert_pem);
+
+ return 1;
+ }
+@end verbatim
+@noindent
+
+
+The rest consists of little new besides some additional memory cleanups.
+@verbatim
+
+ getchar ();
+
+ MHD_stop_daemon (daemon);
+ free (key_pem);
+ free (cert_pem);
+
+ return 0;
+}
+@end verbatim
+@noindent
+
+
+The rather unexciting file loader can be found in the complete example @code{tlsauthentication.c}.
+
+
+@heading Remarks
+@itemize @bullet
+@item
+While the standard @emph{HTTP} port is 80, it is 443 for @emph{HTTPS}. The common internet browsers assume
+standard @emph{HTTP} if they are asked to access other ports than these. Therefore, you will have to type
+@code{https://localhost:8888} explicitly when you test the example, or the browser will not know how to
+handle the answer properly.
+
+@item
+The remaining weak point is the question how the server will be trusted initially. Either a @emph{CA} signs the
+certificate or the client obtains the key over secure means. Anyway, the clients have to be aware (or configured)
+that they should not accept certificates of unknown origin.
+
+@item
+The introduced method of certificates makes it mandatory to set an expiration date---making it less feasible to
+hardcode certificates in embedded devices.
+
+@item
+The cryptographic facilities consume memory space and computing time. For this reason, websites usually consists
+both of uncritically @emph{HTTP} parts and secured @emph{HTTPS}.
+
+@end itemize
+
+
+@heading Client authentication
+
+You can also use MHD to authenticate the client via SSL/TLS certificates
+(as an alternative to using the password-based Basic or Digest authentication).
+To do this, you will need to link your application against @emph{gnutls}.
+Next, when you start the MHD daemon, you must specify the root CA that you're
+willing to trust:
+@verbatim
+ daemon = MHD_start_daemon (MHD_USE_SELECT_INTERNALLY | MHD_USE_SSL,
+ PORT, NULL, NULL,
+ &answer_to_connection, NULL,
+ MHD_OPTION_HTTPS_MEM_KEY, key_pem,
+ MHD_OPTION_HTTPS_MEM_CERT, cert_pem,
+ MHD_OPTION_HTTPS_MEM_TRUST, root_ca_pem,
+ MHD_OPTION_END);
+@end verbatim
+
+With this, you can then obtain client certificates for each session.
+In order to obtain the identity of the client, you first need to
+obtain the raw GnuTLS session handle from @emph{MHD} using
+@code{MHD_get_connection_info}.
+
+@verbatim
+#include <gnutls/gnutls.h>
+#include <gnutls/x509.h>
+
+gnutls_session_t tls_session;
+union MHD_ConnectionInfo *ci;
+
+ci = MHD_get_connection_info (connection,
+ MHD_CONNECTION_INFO_GNUTLS_SESSION);
+tls_session = ci->tls_session;
+@end verbatim
+
+You can then extract the client certificate:
+
+@verbatim
+/**
+ * Get the client's certificate
+ *
+ * @param tls_session the TLS session
+ * @return NULL if no valid client certificate could be found, a pointer
+ * to the certificate if found
+ */
+static gnutls_x509_crt_t
+get_client_certificate (gnutls_session_t tls_session)
+{
+ unsigned int listsize;
+ const gnutls_datum_t * pcert;
+ gnutls_certificate_status_t client_cert_status;
+ gnutls_x509_crt_t client_cert;
+
+ if (tls_session == NULL)
+ return NULL;
+ if (gnutls_certificate_verify_peers2(tls_session,
+ &client_cert_status))
+ return NULL;
+ pcert = gnutls_certificate_get_peers(tls_session,
+ &listsize);
+ if ( (pcert == NULL) ||
+ (listsize == 0))
+ {
+ fprintf (stderr,
+ "Failed to retrieve client certificate chain\n");
+ return NULL;
+ }
+ if (gnutls_x509_crt_init(&client_cert))
+ {
+ fprintf (stderr,
+ "Failed to initialize client certificate\n");
+ return NULL;
+ }
+ /* Note that by passing values between 0 and listsize here, you
+ can get access to the CA's certs */
+ if (gnutls_x509_crt_import(client_cert,
+ &pcert[0],
+ GNUTLS_X509_FMT_DER))
+ {
+ fprintf (stderr,
+ "Failed to import client certificate\n");
+ gnutls_x509_crt_deinit(client_cert);
+ return NULL;
+ }
+ return client_cert;
+}
+@end verbatim
+
+Using the client certificate, you can then get the client's distinguished name
+and alternative names:
+
+@verbatim
+/**
+ * Get the distinguished name from the client's certificate
+ *
+ * @param client_cert the client certificate
+ * @return NULL if no dn or certificate could be found, a pointer
+ * to the dn if found
+ */
+char *
+cert_auth_get_dn(gnutls_x509_crt_c client_cert)
+{
+ char* buf;
+ size_t lbuf;
+
+ lbuf = 0;
+ gnutls_x509_crt_get_dn(client_cert, NULL, &lbuf);
+ buf = malloc(lbuf);
+ if (buf == NULL)
+ {
+ fprintf (stderr,
+ "Failed to allocate memory for certificate dn\n");
+ return NULL;
+ }
+ gnutls_x509_crt_get_dn(client_cert, buf, &lbuf);
+ return buf;
+}
+
+
+/**
+ * Get the alternative name of specified type from the client's certificate
+ *
+ * @param client_cert the client certificate
+ * @param nametype The requested name type
+ * @param index The position of the alternative name if multiple names are
+ * matching the requested type, 0 for the first matching name
+ * @return NULL if no matching alternative name could be found, a pointer
+ * to the alternative name if found
+ */
+char *
+MHD_cert_auth_get_alt_name(gnutls_x509_crt_t client_cert,
+ int nametype,
+ unsigned int index)
+{
+ char* buf;
+ size_t lbuf;
+ unsigned int seq;
+ unsigned int subseq;
+ unsigned int type;
+ int result;
+
+ subseq = 0;
+ for (seq=0;;seq++)
+ {
+ lbuf = 0;
+ result = gnutls_x509_crt_get_subject_alt_name2(client_cert, seq, NULL, &lbuf,
+ &type, NULL);
+ if (result == GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE)
+ return NULL;
+ if (nametype != (int) type)
+ continue;
+ if (subseq == index)
+ break;
+ subseq++;
+ }
+ buf = malloc(lbuf);
+ if (buf == NULL)
+ {
+ fprintf (stderr,
+ "Failed to allocate memory for certificate alt name\n");
+ return NULL;
+ }
+ result = gnutls_x509_crt_get_subject_alt_name2(client_cert,
+ seq,
+ buf,
+ &lbuf,
+ NULL, NULL);
+ if (result != nametype)
+ {
+ fprintf (stderr,
+ "Unexpected return value from gnutls: %d\n",
+ result);
+ free (buf);
+ return NULL;
+ }
+ return buf;
+}
+@end verbatim
+
+Finally, you should release the memory associated with the client
+certificate:
+
+@verbatim
+gnutls_x509_crt_deinit (client_cert);
+@end verbatim
+
+
+
+@heading Using TLS Server Name Indication (SNI)
+
+SNI enables hosting multiple domains under one IP address with TLS. So
+SNI is the TLS-equivalent of virtual hosting. To use SNI with MHD, you
+need at least GnuTLS 3.0. The main change compared to the simple hosting
+of one domain is that you need to provide a callback instead of the key
+and certificate. For example, when you start the MHD daemon, you could
+do this:
+@verbatim
+ daemon = MHD_start_daemon (MHD_USE_SELECT_INTERNALLY | MHD_USE_SSL,
+ PORT, NULL, NULL,
+ &answer_to_connection, NULL,
+ MHD_OPTION_HTTPS_CERT_CALLBACK, &sni_callback,
+ MHD_OPTION_END);
+@end verbatim
+Here, @code{sni_callback} is the name of a function that you will have to
+implement to retrieve the X.509 certificate for an incoming connection.
+The callback has type @code{gnutls_certificate_retrieve_function2} and
+is documented in the GnuTLS API for the @code{gnutls_certificate_set_retrieve_function2}
+as follows:
+
+@deftypefn {Function Pointer} int {*gnutls_certificate_retrieve_function2} (gnutls_session_t, const gnutls_datum_t* req_ca_dn, int nreqs, const gnutls_pk_algorithm_t* pk_algos, int pk_algos_length, gnutls_pcert_st** pcert, unsigned int *pcert_length, gnutls_privkey_t * pkey)
+
+@table @var
+@item req_ca_cert
+is only used in X.509 certificates. Contains a list with the CA names that the server considers trusted. Normally we should send a certificate that is signed by one of these CAs. These names are DER encoded. To get a more meaningful value use the function @code{gnutls_x509_rdn_get()}.
+
+@item pk_algos
+contains a list with server’s acceptable signature algorithms. The certificate returned should support the server’s given algorithms.
+
+@item pcert
+should contain a single certificate and public or a list of them.
+
+@item pcert_length
+is the size of the previous list.
+
+@item pkey
+is the private key.
+@end table
+@end deftypefn
+
+A possible implementation of this callback would look like this:
+
+@verbatim
+struct Hosts
+{
+ struct Hosts *next;
+ const char *hostname;
+ gnutls_pcert_st pcrt;
+ gnutls_privkey_t key;
+};
+
+static struct Hosts *hosts;
+
+int
+sni_callback (gnutls_session_t session,
+ const gnutls_datum_t* req_ca_dn,
+ int nreqs,
+ const gnutls_pk_algorithm_t* pk_algos,
+ int pk_algos_length,
+ gnutls_pcert_st** pcert,
+ unsigned int *pcert_length,
+ gnutls_privkey_t * pkey)
+{
+ char name[256];
+ size_t name_len;
+ struct Hosts *host;
+ unsigned int type;
+
+ name_len = sizeof (name);
+ if (GNUTLS_E_SUCCESS !=
+ gnutls_server_name_get (session,
+ name,
+ &name_len,
+ &type,
+ 0 /* index */))
+ return -1;
+ for (host = hosts; NULL != host; host = host->next)
+ if (0 == strncmp (name, host->hostname, name_len))
+ break;
+ if (NULL == host)
+ {
+ fprintf (stderr,
+ "Need certificate for %.*s\n",
+ (int) name_len,
+ name);
+ return -1;
+ }
+ fprintf (stderr,
+ "Returning certificate for %.*s\n",
+ (int) name_len,
+ name);
+ *pkey = host->key;
+ *pcert_length = 1;
+ *pcert = &host->pcrt;
+ return 0;
+}
+@end verbatim
+
+Note that MHD cannot offer passing a closure or any other additional information
+to this callback, as the GnuTLS API unfortunately does not permit this at this
+point.
+
+The @code{hosts} list can be initialized by loading the private keys and X.509
+certificats from disk as follows:
+
+@verbatim
+static void
+load_keys(const char *hostname,
+ const char *CERT_FILE,
+ const char *KEY_FILE)
+{
+ int ret;
+ gnutls_datum_t data;
+ struct Hosts *host;
+
+ host = malloc (sizeof (struct Hosts));
+ host->hostname = hostname;
+ host->next = hosts;
+ hosts = host;
+
+ ret = gnutls_load_file (CERT_FILE, &data);
+ if (ret < 0)
+ {
+ fprintf (stderr,
+ "*** Error loading certificate file %s.\n",
+ CERT_FILE);
+ exit(1);
+ }
+ ret =
+ gnutls_pcert_import_x509_raw (&host->pcrt, &data, GNUTLS_X509_FMT_PEM,
+ 0);
+ if (ret < 0)
+ {
+ fprintf(stderr,
+ "*** Error loading certificate file: %s\n",
+ gnutls_strerror (ret));
+ exit(1);
+ }
+ gnutls_free (data.data);
+
+ ret = gnutls_load_file (KEY_FILE, &data);
+ if (ret < 0)
+ {
+ fprintf (stderr,
+ "*** Error loading key file %s.\n",
+ KEY_FILE);
+ exit(1);
+ }
+
+ gnutls_privkey_init (&host->key);
+ ret =
+ gnutls_privkey_import_x509_raw (host->key,
+ &data, GNUTLS_X509_FMT_PEM,
+ NULL, 0);
+ if (ret < 0)
+ {
+ fprintf (stderr,
+ "*** Error loading key file: %s\n",
+ gnutls_strerror (ret));
+ exit(1);
+ }
+ gnutls_free (data.data);
+}
+@end verbatim
+
+The code above was largely lifted from GnuTLS. You can find other
+methods for initializing certificates and keys in the GnuTLS manual
+and source code.

+@center Version 2, June 1991
+
+@display
+Copyright @copyright{} 1989, 1991 Free Software Foundation, Inc.
+59 Temple Place -- Suite 330, Boston, MA 02111-1307, USA
+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+@end display
+
+
+
+
+@subheading Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software---to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+@iftex
+@subheading TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+@end iftex
+@ifinfo
+@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+@end ifinfo
+
+@enumerate
+@item
+This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The ``Program'', below,
+refers to any such program or work, and a ``work based on the Program''
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term ``modification''.) Each licensee is addressed as ``you''.
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+@item
+You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+@item
+You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+@enumerate a
+@item
+You must cause the modified files to carry prominent notices
+stating that you changed the files and the date of any change.
+
+@item
+You must cause any work that you distribute or publish, that in
+whole or in part contains or is derived from the Program or any
+part thereof, to be licensed as a whole at no charge to all third
+parties under the terms of this License.
+
+@item
+If the modified program normally reads commands interactively
+when run, you must cause it, when started running for such
+interactive use in the most ordinary way, to print or display an
+announcement including an appropriate copyright notice and a
+notice that there is no warranty (or else, saying that you provide
+a warranty) and that users may redistribute the program under
+these conditions, and telling the user how to view a copy of this
+License. (Exception: if the Program itself is interactive but
+does not normally print such an announcement, your work based on
+the Program is not required to print an announcement.)
+@end enumerate
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+@item
+You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+@enumerate a
+@item
+Accompany it with the complete corresponding machine-readable
+source code, which must be distributed under the terms of Sections
+1 and 2 above on a medium customarily used for software interchange; or,
+
+@item
+Accompany it with a written offer, valid for at least three
+years, to give any third party, for a charge no more than your
+cost of physically performing source distribution, a complete
+machine-readable copy of the corresponding source code, to be
+distributed under the terms of Sections 1 and 2 above on a medium
+customarily used for software interchange; or,
+
+@item
+Accompany it with the information you received as to the offer
+to distribute corresponding source code. (This alternative is
+allowed only for noncommercial distribution and only if you
+received the program in object code or executable form with such
+an offer, in accord with Subsection b above.)
+@end enumerate
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+@item
+You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+@item
+You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+@item
+Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+@item
+If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+@item
+If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+@item
+The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and ``any
+later version'', you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+@item
+If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+@center @b{NO WARRANTY}
+
+@item
+BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM ``AS IS'' WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+@item
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.

+@item
+As a special exception, if other files instantiate templates or use
+macros or inline functions from this file, or you compile this file
+and link it with other works to produce a work based on this file,
+this file does not by itself cause the resulting work to be covered by
+the GNU General Public License. However the source code for this file

+@page
+@unnumberedsec How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the ``copyright'' line and a pointer to where the full notice is found.
+
+@smallexample
+@var{one line to give the program's name and an idea of what it does.}
+Copyright (C) 19@var{yy} @var{name of author}

+modify it under the terms of the GNU General Public License
+as published by the Free Software Foundation; either version 2
+of the License, or (at your option) any later version.
+
+This program is distributed in the hope that it will be useful,
+but WITHOUT ANY WARRANTY; without even the implied warranty of
+MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+GNU General Public License for more details.

+You should have received a copy of the GNU General Public License along
+with this program; if not, write to the Free Software Foundation, Inc.,
+59 Temple Place, Suite 330, Boston, MA 02111-1307, USA.
+@end smallexample
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+@smallexample
+Gnomovision version 69, Copyright (C) 19@var{yy} @var{name of author}
+Gnomovision comes with ABSOLUTELY NO WARRANTY; for details
+type `show w'. This is free software, and you are welcome
+to redistribute it under certain conditions; type `show c'
+for details.
+@end smallexample
+
+The hypothetical commands @samp{show w} and @samp{show c} should show
+the appropriate parts of the General Public License. Of course, the
+commands you use may be called something other than @samp{show w} and
+@samp{show c}; they could even be mouse-clicks or menu items---whatever
+suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a ``copyright disclaimer'' for the program, if
+necessary. Here is a sample; alter the names:
+
+@smallexample
+@group
+Yoyodyne, Inc., hereby disclaims all copyright
+interest in the program `Gnomovision'

+Public License instead of this License.

+Copyright @copyright{} 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.

+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+@end display
+
+@enumerate 0
+@item
+PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document @dfn{free} in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of ``copyleft'', which means that derivative
+works of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does. But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book. We recommend this License
+principally for works whose purpose is instruction or reference.
+
+@item
+APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License. Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein. The ``Document'', below,
+refers to any such manual or work. Any member of the public is a
+licensee, and is addressed as ``you''. You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A ``Modified Version'' of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A ``Secondary Section'' is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject. (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The ``Invariant Sections'' are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License. If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant. The Document may contain zero
+Invariant Sections. If the Document does not identify any Invariant
+Sections then there are none.
+
+The ``Cover Texts'' are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License. A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A ``Transparent'' copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text. A copy that is not ``Transparent'' is called ``Opaque''.
+
+Examples of suitable formats for Transparent copies include plain
+@sc{ascii} without markup, Texinfo input format, La@TeX{} input
+format, @acronym{SGML} or @acronym{XML} using a publicly available
+@acronym{DTD}, and standard-conforming simple @acronym{HTML},
+PostScript or @acronym{PDF} designed for human modification. Examples
+of transparent image formats include @acronym{PNG}, @acronym{XCF} and
+@acronym{JPG}. Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, @acronym{SGML} or
+@acronym{XML} for which the @acronym{DTD} and/or processing tools are
+not generally available, and the machine-generated @acronym{HTML},
+PostScript or @acronym{PDF} produced by some word processors for
+output purposes only.
+
+The ``Title Page'' means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, ``Title Page'' means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+The ``publisher'' means any person or entity that distributes copies
+of the Document to the public.
+
+A section ``Entitled XYZ'' means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language. (Here XYZ stands for a
+specific section name mentioned below, such as ``Acknowledgements'',
+``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title''
+of such a section when you modify the Document means that it remains a
+section ``Entitled XYZ'' according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document. These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+@item
+VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+@item
+COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+@item
+MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+@enumerate A
+@item
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document). You may use the same title as a previous version
+if the original publisher of that version gives permission.
+
+@item
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+
+@item
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+@item
+Preserve all the copyright notices of the Document.
+
+@item
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+@item
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+
+@item
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+
+@item
+Include an unaltered copy of this License.
+
+@item
+Preserve the section Entitled ``History'', Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page. If
+there is no section Entitled ``History'' in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+
+@item
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on. These may be placed in the ``History'' section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+
+@item
+For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+
+@item
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles. Section numbers
+or the equivalent are not considered part of the section titles.
+
+@item
+Delete any section Entitled ``Endorsements''. Such a section
+may not be included in the Modified Version.
+
+@item
+Do not retitle any existing section to be Entitled ``Endorsements'' or
+to conflict in title with any Invariant Section.
+
+@item
+Preserve any Warranty Disclaimers.
+@end enumerate
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled ``Endorsements'', provided it contains
+nothing but endorsements of your Modified Version by various
+parties---for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+@item
+COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled ``History''
+in the various original documents, forming one section Entitled
+``History''; likewise combine any sections Entitled ``Acknowledgements'',
+and any sections Entitled ``Dedications''. You must delete all
+sections Entitled ``Endorsements.''
+
+@item
+COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+@item
+AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an ``aggregate'' if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+@item
+TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers. In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled ``Acknowledgements'',
+``Dedications'', or ``History'', the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+@item
+TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, receipt of a copy of some or all of the same material does
+not give you any rights to use it.
+
+@item
+FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns. See
+@uref{http://www.gnu.org/copyleft/}.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License ``or any later version'' applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation. If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation. If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.
+
+@item
+RELICENSING
+
+``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any
+World Wide Web server that publishes copyrightable works and also
+provides prominent facilities for anybody to edit those works. A
+public wiki that anybody can edit is an example of such a server. A
+``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the
+site means any set of copyrightable works thus published on the MMC
+site.
+
+``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0
+license published by Creative Commons Corporation, a not-for-profit
+corporation with a principal place of business in San Francisco,
+California, as well as future copyleft versions of that license
+published by that same organization.
+
+``Incorporate'' means to publish or republish a Document, in whole or
+in part, as part of another Document.
+
+An MMC is ``eligible for relicensing'' if it is licensed under this
+License, and if all works that were first published under this License
+somewhere other than this MMC, and subsequently incorporated in whole
+or in part into the MMC, (1) had no cover texts or invariant sections,
+and (2) were thus incorporated prior to November 1, 2008.
+
+The operator of an MMC Site may republish an MMC contained in the site
+under CC-BY-SA on the same site at any time before August 1, 2009,
+provided the MMC is eligible for relicensing.

+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+

+as the successor of the GNU Library Public License, version 2, hence the
+version number 2.1.]
+@end display
+
+@subheading Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software---to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software---typically libraries---of the Free
+Software Foundation and other authors who decide to use it. You can use
+it too, but we suggest you first think carefully about whether this
+license or the ordinary General Public License is the better strategy to
+use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of it
+in new free programs; and that you are informed that you can do these
+things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the @dfn{Lesser} General Public License because it
+does @emph{Less} to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+``work based on the library'' and a ``work that uses the library''. The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+@subheading TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+@enumerate 0
+@item
+This License Agreement applies to any software library or other program
+which contains a notice placed by the copyright holder or other
+authorized party saying it may be distributed under the terms of this
+Lesser General Public License (also called ``this License''). Each
+licensee is addressed as ``you''.
+
+ A ``library'' means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The ``Library'', below, refers to any such software library or work
+which has been distributed under these terms. A ``work based on the
+Library'' means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term ``modification''.)
+
+ ``Source code'' for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+@item
+You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+@item
+You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+@enumerate a
+@item
+The modified work must itself be a software library.
+
+@item
+You must cause the files modified to carry prominent notices
+stating that you changed the files and the date of any change.
+
+@item
+You must cause the whole of the work to be licensed at no
+charge to all third parties under the terms of this License.
+
+@item
+If a facility in the modified Library refers to a function or a
+table of data to be supplied by an application program that uses
+the facility, other than as an argument passed when the facility
+is invoked, then you must make a good faith effort to ensure that,
+in the event an application does not supply such function or
+table, the facility still operates, and performs whatever part of
+its purpose remains meaningful.
+
+(For example, a function in a library to compute square roots has
+a purpose that is entirely well-defined independent of the
+application. Therefore, Subsection 2d requires that any
+application-supplied function or table used by this function must
+be optional: if the application does not supply it, the square
+root function must still compute square roots.)
+@end enumerate
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+@item
+You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+@item
+You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+@item
+A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a ``work that uses the Library''. Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a ``work that uses the Library'' with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a ``work that uses the
+library''. The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a ``work that uses the Library'' uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+@item
+As an exception to the Sections above, you may also combine or
+link a ``work that uses the Library'' with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+@enumerate a
+@item
+Accompany the work with the complete corresponding
+machine-readable source code for the Library including whatever
+changes were used in the work (which must be distributed under
+Sections 1 and 2 above); and, if the work is an executable linked
+with the Library, with the complete machine-readable ``work that
+uses the Library'', as object code and/or source code, so that the
+user can modify the Library and then relink to produce a modified
+executable containing the modified Library. (It is understood
+that the user who changes the contents of definitions files in the
+Library will not necessarily be able to recompile the application
+to use the modified definitions.)
+
+@item
+Use a suitable shared library mechanism for linking with the Library. A
+suitable mechanism is one that (1) uses at run time a copy of the
+library already present on the user's computer system, rather than
+copying library functions into the executable, and (2) will operate
+properly with a modified version of the library, if the user installs
+one, as long as the modified version is interface-compatible with the
+version that the work was made with.
+
+@item
+Accompany the work with a written offer, valid for at
+least three years, to give the same user the materials
+specified in Subsection 6a, above, for a charge no more
+than the cost of performing this distribution.
+
+@item
+If distribution of the work is made by offering access to copy
+from a designated place, offer equivalent access to copy the above
+specified materials from the same place.
+
+@item
+Verify that the user has already received a copy of these
+materials or that you have already sent this user a copy.
+@end enumerate
+
+ For an executable, the required form of the ``work that uses the
+Library'' must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies the
+executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+@item
+You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+@enumerate a
+@item
+Accompany the combined library with a copy of the same work
+based on the Library, uncombined with any other library
+facilities. This must be distributed under the terms of the
+Sections above.
+
+@item
+Give prominent notice with the combined library of the fact
+that part of it is a work based on the Library, and explaining
+where to find the accompanying uncombined form of the same work.
+@end enumerate
+
+@item
+You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+@item
+You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+@item
+Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+@item
+If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+@item
+If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+@item
+The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+``any later version'', you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+@item
+If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+@center @b{NO WARRANTY}
+
+@item
+BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY ``AS IS'' WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+@item
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.

+ If you develop a new library, and you want it to be of the greatest

+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively

+1 Introduction
+**************
+
+This tutorial is for developers who want to learn how they can add HTTP
+serving capabilities to their applications with the _GNU libmicrohttpd_
+library, abbreviated _MHD_. The reader will learn how to implement
+basic HTTP functions from simple executable sample programs that
+implement various features.
+
+ The text is supposed to be a supplement to the API reference manual
+of _GNU libmicrohttpd_ and for that reason does not explain many of the
+parameters. Therefore, the reader should always consult the manual to
+find the exact meaning of the functions used in the tutorial.
+Furthermore, the reader is encouraged to study the relevant _RFCs_,
+which document the HTTP standard.
+
+ _GNU libmicrohttpd_ is assumed to be already installed. This
+tutorial is written for version 0.9.23. At the time being, this
+tutorial has only been tested on _GNU/Linux_ machines even though
+efforts were made not to rely on anything that would prevent the
+samples from being built on similar systems.
+
+1.1 History
+===========
+
+This tutorial was originally written by Sebastian Gerhardt for MHD
+0.4.0. It was slighly polished and updated to MHD 0.9.0 by Christian
+Grothoff.
+
+
+File: libmicrohttpd-tutorial.info, Node: Hello browser example, Next: Exploring requests, Prev: Introduction, Up: Top
+
+2 Hello browser example
+***********************
+
+The most basic task for a HTTP server is to deliver a static text
+message to any client connecting to it. Given that this is also easy
+to implement, it is an excellent problem to start with.
+
+ For now, the particular URI the client asks for shall have no effect
+on the message that will be returned. In addition, the server shall end
+the connection after the message has been sent so that the client will
+know there is nothing more to expect.
+
+ The C program `hellobrowser.c', which is to be found in the examples
+section, does just that. If you are very eager, you can compile and
+start it right away but it is advisable to type the lines in by
+yourself as they will be discussed and explained in detail.
+
+ After the necessary includes and the definition of the port which
+our server should listen on
+#include <sys/types.h>
+#include <sys/select.h>
+#include <sys/socket.h>
+#include <microhttpd.h>
+
+#define PORT 8888
+
+the desired behaviour of our server when HTTP request arrive has to be
+implemented. We already have agreed that it should not care about the
+particular details of the request, such as who is requesting what. The
+server will respond merely with the same small HTML page to every
+request.
+
+ The function we are going to write now will be called by _GNU
+libmicrohttpd_ every time an appropriate request comes in. While the
+name of this callback function is arbitrary, its parameter list has to
+follow a certain layout. So please, ignore the lot of parameters for
+now, they will be explained at the point they are needed. We have to
+use only one of them, `struct MHD_Connection *connection', for the
+minimalistic functionality we want to archive at the moment.
+
+ This parameter is set by the _libmicrohttpd_ daemon and holds the
+necessary information to relate the call with a certain connection.
+Keep in mind that a server might have to satisfy hundreds of concurrent
+connections and we have to make sure that the correct data is sent to
+the destined client. Therefore, this variable is a means to refer to a
+particular connection if we ask the daemon to sent the reply.
+
+ Talking about the reply, it is defined as a string right after the
+function header
+int answer_to_connection (void *cls, struct MHD_Connection *connection,
+ const char *url,
+ const char *method, const char *version,
+ const char *upload_data,
+ size_t *upload_data_size, void **con_cls)
+{
+ const char *page = "<html><body>Hello, browser!</body></html>";
+
+HTTP is a rather strict protocol and the client would certainly
+consider it "inappropriate" if we just sent the answer string "as is".
+Instead, it has to be wrapped with additional information stored in
+so-called headers and footers. Most of the work in this area is done
+by the library for us--we just have to ask. Our reply string packed in
+the necessary layers will be called a "response". To obtain such a
+response we hand our data (the reply-string) and its size over to the
+`MHD_create_response_from_buffer' function. The last two parameters
+basically tell _MHD_ that we do not want it to dispose the message data
+for us when it has been sent and there also needs no internal copy to
+be done because the _constant_ string won't change anyway.
+
+ struct MHD_Response *response;
+ int ret;
+
+ response = MHD_create_response_from_buffer (strlen (page),
+ (void*) page, MHD_RESPMEM_PERSISTENT);
+
+Now that the the response has been laced up, it is ready for delivery
+and can be queued for sending. This is done by passing it to another
+_GNU libmicrohttpd_ function. As all our work was done in the scope of
+one function, the recipient is without doubt the one associated with the
+local variable `connection' and consequently this variable is given to
+the queue function. Every HTTP response is accompanied by a status
+code, here "OK", so that the client knows this response is the intended
+result of his request and not due to some error or malfunction.
+
+ Finally, the packet is destroyed and the return value from the queue
+returned, already being set at this point to either MHD_YES or MHD_NO
+in case of success or failure.
+
+ ret = MHD_queue_response (connection, MHD_HTTP_OK, response);
+ MHD_destroy_response (response);
+
+ return ret;
+}
+
+With the primary task of our server implemented, we can start the
+actual server daemon which will listen on `PORT' for connections. This
+is done in the main function.
+int main ()
+{
+ struct MHD_Daemon *daemon;
+
+ daemon = MHD_start_daemon (MHD_USE_SELECT_INTERNALLY, PORT, NULL, NULL,
+ &answer_to_connection, NULL, MHD_OPTION_END);
+ if (NULL == daemon) return 1;
+
+The first parameter is one of three possible modes of operation. Here
+we want the daemon to run in a separate thread and to manage all
+incoming connections in the same thread. This means that while
+producing the response for one connection, the other connections will
+be put on hold. In this example, where the reply is already known and
+therefore the request is served quickly, this poses no problem.
+
+ We will allow all clients to connect regardless of their name or
+location, therefore we do not check them on connection and set the
+forth and fifth parameter to NULL.
+
+ Parameter six is the address of the function we want to be called
+whenever a new connection has been established. Our
+`answer_to_connection' knows best what the client wants and needs no
+additional information (which could be passed via the next parameter)
+so the next parameter is NULL. Likewise, we do not need to pass extra
+options to the daemon so we just write the MHD_OPTION_END as the last
+parameter.
+
+ As the server daemon runs in the background in its own thread, the
+execution flow in our main function will contine right after the call.
+Because of this, we must delay the execution flow in the main thread or
+else the program will terminate prematurely. We let it pause in a
+processing-time friendly manner by waiting for the enter key to be
+pressed. In the end, we stop the daemon so it can do its cleanup tasks.
+ getchar ();
+
+ MHD_stop_daemon (daemon);
+ return 0;
+}
+
+The first example is now complete.
+
+ Compile it with
+cc hellobrowser.c -o hellobrowser -I$PATH_TO_LIBMHD_INCLUDES
+ -L$PATH_TO_LIBMHD_LIBS -lmicrohttpd
+ with the two paths set accordingly and run it.
+
+ Now open your favorite Internet browser and go to the address
+`http://localhost:8888/', provided that 8888 is the port you chose. If
+everything works as expected, the browser will present the message of
+the static HTML page it got from our minimal server.
+
+Remarks
+=======
+
+To keep this first example as small as possible, some drastic shortcuts
+were taken and are to be discussed now.
+
+ Firstly, there is no distinction made between the kinds of requests
+a client could send. We implied that the client sends a GET request,
+that means, that he actually asked for some data. Even when it is not
+intended to accept POST requests, a good server should at least
+recognize that this request does not constitute a legal request and
+answer with an error code. This can be easily implemented by checking
+if the parameter `method' equals the string "GET" and returning a
+`MHD_NO' if not so.
+
+ Secondly, the above practice of queuing a response upon the first
+call of the callback function brings with it some limitations. This is
+because the content of the message body will not be received if a
+response is queued in the first iteration. Furthermore, the connection
+will be closed right after the response has been transferred then.
+This is typically not what you want as it disables HTTP pipelining.
+The correct approach is to simply not queue a message on the first
+callback unless there is an error. The `void**' argument to the
+callback provides a location for storing information about the history
+of the connection; for the first call, the pointer will point to NULL.
+A simplistic way to differenciate the first call from others is to check
+if the pointer is NULL and set it to a non-NULL value during the first
+call.
+
+ Both of these issues you will find addressed in the official
+`minimal_example.c' residing in the `src/examples' directory of the
+_MHD_ package. The source code of this program should look very
+familiar to you by now and easy to understand.
+
+ For our example, the `must_copy' and `must_free' parameter at the
+response construction function could be set to `MHD_NO'. In the usual
+case, responses cannot be sent immediately after being queued. For
+example, there might be other data on the system that needs to be sent
+with a higher priority. Nevertheless, the queue function will return
+successfully--raising the problem that the data we have pointed to may
+be invalid by the time it is about being sent. This is not an issue
+here because we can expect the `page' string, which is a constant
+_string literal_ here, to be static. That means it will be present and
+unchanged for as long as the program runs. For dynamic data, one could
+choose to either have _MHD_ free the memory `page' points to itself
+when it is not longer needed or, alternatively, have the library to
+make and manage its own copy of it.
+
+Exercises
+=========
+
+ * While the server is running, use a program like `telnet' or
+ `netcat' to connect to it. Try to form a valid HTTP 1.1 request
+ yourself like GET /dontcare HTTP/1.1
+ Host: itsme
+ <enter>
+ and see what the server returns to you.
+
+ * Also, try other requests, like POST, and see how our server does
+ not mind and why. How far in malforming a request can you go
+ before the builtin functionality of _MHD_ intervenes and an
+ altered response is sent? Make sure you read about the status
+ codes in the _RFC_.
+
+ * Add the option `MHD_USE_PEDANTIC_CHECKS' to the start function of
+ the daemon in `main'. Mind the special format of the parameter
+ list here which is described in the manual. How indulgent is the
+ server now to your input?
+
+ * Let the main function take a string as the first command line
+ argument and pass `argv[1]' to the `MHD_start_daemon' function as
+ the sixth parameter. The address of this string will be passed to
+ the callback function via the `cls' variable. Decorate the text
+ given at the command line when the server is started with proper
+ HTML tags and send it as the response instead of the former static
+ string.
+
+ * _Demanding:_ Write a separate function returning a string
+ containing some useful information, for example, the time. Pass
+ the function's address as the sixth parameter and evaluate this
+ function on every request anew in `answer_to_connection'. Remember
+ to free the memory of the string every time after satisfying the
+ request.

+3 Exploring requests
+********************
+
+This chapter will deal with the information which the client sends to
+the server at every request. We are going to examine the most useful
+fields of such an request and print them out in a readable manner. This
+could be useful for logging facilities.
+
+ The starting point is the _hellobrowser_ program with the former
+response removed.
+
+ This time, we just want to collect information in the callback
+function, thus we will just return MHD_NO after we have probed the
+request. This way, the connection is closed without much ado by the
+server.
+
+static int
+answer_to_connection (void *cls, struct MHD_Connection *connection,
+ const char *url,
+ const char *method, const char *version,
+ const char *upload_data,
+ size_t *upload_data_size, void **con_cls)
+{
+ ...
+ return MHD_NO;
+}
+ The ellipsis marks the position where the following instructions shall
+be inserted.
+
+ We begin with the most obvious information available to the server,
+the request line. You should already have noted that a request consists
+of a command (or "HTTP method") and a URI (e.g. a filename). It also
+contains a string for the version of the protocol which can be found in
+`version'. To call it a "new request" is justified because we return
+only `MHD_NO', thus ensuring the function will not be called again for
+this connection.
+printf ("New %s request for %s using version %s\n", method, url, version);
+ The rest of the information is a bit more hidden. Nevertheless, there
+is lot of it sent from common Internet browsers. It is stored in
+"key-value" pairs and we want to list what we find in the header. As
+there is no mandatory set of keys a client has to send, each key-value
+pair is printed out one by one until there are no more left. We do this
+by writing a separate function which will be called for each pair just
+like the above function is called for each HTTP request. It can then
+print out the content of this pair.
+int print_out_key (void *cls, enum MHD_ValueKind kind,
+ const char *key, const char *value)
+{
+ printf ("%s: %s\n", key, value);
+ return MHD_YES;
+}
+ To start the iteration process that calls our new function for every
+key, the line
+MHD_get_connection_values (connection, MHD_HEADER_KIND, &print_out_key, NULL);
+ needs to be inserted in the connection callback function too. The
+second parameter tells the function that we are only interested in keys
+from the general HTTP header of the request. Our iterating function
+`print_out_key' does not rely on any additional information to fulfill
+its duties so the last parameter can be NULL.
+
+ All in all, this constitutes the complete `logging.c' program for
+this chapter which can be found in the `examples' section.
+
+ Connecting with any modern Internet browser should yield a handful
+of keys. You should try to interpret them with the aid of _RFC 2616_.
+Especially worth mentioning is the "Host" key which is often used to
+serve several different websites hosted under one single IP address but
+reachable by different domain names (this is called virtual hosting).
+
+Conclusion
+==========
+
+The introduced capabilities to itemize the content of a simple GET
+request--especially the URI--should already allow the server to satisfy
+clients' requests for small specific resources (e.g. files) or even
+induce alteration of server state. However, the latter is not
+recommended as the GET method (including its header data) is by
+convention considered a "safe" operation, which should not change the
+server's state in a significant way. By convention, GET operations can
+thus be performed by crawlers and other automatic software. Naturally
+actions like searching for a passed string are fine.
+
+ Of course, no transmission can occur while the return value is still
+set to `MHD_NO' in the callback function.
+
+Exercises
+=========
+
+ * By parsing the `url' string and delivering responses accordingly,
+ implement a small server for "virtual" files. When asked for
+ `/index.htm{l}', let the response consist of a HTML page
+ containing a link to `/another.html' page which is also to be
+ created "on the fly" in case of being requested. If neither of
+ these two pages are requested, `MHD_HTTP_NOT_FOUND' shall be
+ returned accompanied by an informative message.
+
+ * A very interesting information has still been ignored by our
+ logger--the client's IP address. Implement a callback function static int on_client_connect (void *cls,
+ const struct sockaddr *addr,
+ socklen_t addrlen)
+ that prints out the IP address in an appropriate format. You
+ might want to use the POSIX function `inet_ntoa' but bear in mind
+ that `addr' is actually just a structure containing other
+ substructures and is _not_ the variable this function expects.
+ Make sure to return `MHD_YES' so that the library knows the client
+ is allowed to connect (and to then process the request). If one
+ wanted to limit access basing on IP addresses, this would be the
+ place to do it. The address of your `on_client_connect' function
+ must be passed as the third parameter to the `MHD_start_daemon'
+ call.

+4 Response headers
+******************
+
+Now that we are able to inspect the incoming request in great detail,
+this chapter discusses the means to enrich the outgoing responses
+likewise.
+
+ As you have learned in the _Hello, Browser_ chapter, some obligatory
+header fields are added and set automatically for simple responses by
+the library itself but if more advanced features are desired,
+additional fields have to be created. One of the possible fields is
+the content type field and an example will be developed around it.
+This will lead to an application capable of correctly serving different
+types of files.
+
+ When we responded with HTML page packed in the static string
+previously, the client had no choice but guessing about how to handle
+the response, because the server had not told him. What if we had sent
+a picture or a sound file? Would the message have been understood or
+merely been displayed as an endless stream of random characters in the
+browser? This is what the mime content types are for. The header of
+the response is extended by certain information about how the data is
+to be interpreted.
+
+ To introduce the concept, a picture of the format _PNG_ will be sent
+to the client and labeled accordingly with `image/png'. Once again, we
+can base the new example on the `hellobrowser' program.
+
+#define FILENAME "picture.png"
+#define MIMETYPE "image/png"
+
+static int
+answer_to_connection (void *cls, struct MHD_Connection *connection,
+ const char *url,
+ const char *method, const char *version,
+ const char *upload_data,
+ size_t *upload_data_size, void **con_cls)
+{
+ unsigned char *buffer = NULL;
+ struct MHD_Response *response;
+ We want the program to open the file for reading and determine its
+size:
+ int fd;
+ int ret;
+ struct stat sbuf;
+
+ if (0 != strcmp (method, "GET"))
+ return MHD_NO;
+ if ( (-1 == (fd = open (FILENAME, O_RDONLY))) ||
+ (0 != fstat (fd, &sbuf)) )
+ {
+ /* error accessing file */
+ /* ... (see below) */
+ }
+ /* ... (see below) */
+ When dealing with files, there is a lot that could go wrong on the
+server side and if so, the client should be informed with
+`MHD_HTTP_INTERNAL_SERVER_ERROR'.
+
+ /* error accessing file */
+ if (fd != -1) close (fd);
+ const char *errorstr =
+ "<html><body>An internal server error has occured!\
+ </body></html>";
+ response =
+ MHD_create_response_from_buffer (strlen (errorstr),
+ (void *) errorstr,
+ MHD_RESPMEM_PERSISTENT);
+ if (response)
+ {
+ ret =
+ MHD_queue_response (connection, MHD_HTTP_INTERNAL_SERVER_ERROR,
+ response);
+ MHD_destroy_response (response);
+
+ return MHD_YES;
+ }
+ else
+ return MHD_NO;
+ if (!ret)
+ {
+ const char *errorstr = "<html><body>An internal server error has occured!\
+ </body></html>";
+
+ if (buffer) free(buffer);
+
+ response = MHD_create_response_from_buffer (strlen(errorstr), (void*) errorstr,
+ MHD_RESPMEM_PERSISTENT);
+
+ if (response)
+ {
+ ret = MHD_queue_response (connection,
+ MHD_HTTP_INTERNAL_SERVER_ERROR,
+ response);
+ MHD_destroy_response (response);
+
+ return MHD_YES;
+ }
+ else return MHD_NO;
+ }
+ Note that we nevertheless have to create a response object even for
+sending a simple error code. Otherwise, the connection would just be
+closed without comment, leaving the client curious about what has
+happened.
+
+ But in the case of success a response will be constructed directly
+from the file descriptor:
+
+ /* error accessing file */
+ /* ... (see above) */
+ }
+
+ response =
+ MHD_create_response_from_fd_at_offset (sbuf.st_size, fd, 0);
+ MHD_add_response_header (response, "Content-Type", MIMETYPE);
+ ret = MHD_queue_response (connection, MHD_HTTP_OK, response);
+ MHD_destroy_response (response);
+ Note that the response object will take care of closing the file
+desciptor for us.
+
+ Up to this point, there was little new. The actual novelty is that
+we enhance the header with the meta data about the content. Aware of
+the field's name we want to add, it is as easy as that:
+MHD_add_response_header(response, "Content-Type", MIMETYPE);
+ We do not have to append a colon expected by the protocol behind the
+first field--_GNU libhttpdmicro_ will take care of this.
+
+ The function finishes with the well-known lines
+ ret = MHD_queue_response (connection, MHD_HTTP_OK, response);
+ MHD_destroy_response (response);
+ return ret;
+}
+ The complete program `responseheaders.c' is in the `examples' section
+as usual. Find a _PNG_ file you like and save it to the directory the
+example is run from under the name `picture.png'. You should find the
+image displayed on your browser if everything worked well.
+
+Remarks
+=======
+
+The include file of the _MHD_ library comes with the header types
+mentioned in _RFC 2616_ already defined as macros. Thus, we could have
+written `MHD_HTTP_HEADER_CONTENT_TYPE' instead of `"Content-Type"' as
+well. However, one is not limited to these standard headers and could
+add custom response headers without violating the protocol. Whether,
+and how, the client would react to these custom header is up to the
+receiver. Likewise, the client is allowed to send custom request
+headers to the server as well, opening up yet more possibilities how
+client and server could communicate with each other.
+
+ The method of creating the response from a file on disk only works
+for static content. Serving dynamically created responses will be a
+topic of a future chapter.
+
+Exercises
+=========
+
+ * Remember that the original program was written under a few
+ assumptions--a static response using a local file being one of
+ them. In order to simulate a very large or hard to reach file that
+ cannot be provided instantly, postpone the queuing in the callback
+ with the `sleep' function for 30 seconds _if_ the file `/big.png'
+ is requested (but deliver the same as above). A request for
+ `/picture.png' should provide just the same but without any
+ artificial delays.
+
+ Now start two instances of your browser (or even use two machines)
+ and see how the second client is put on hold while the first waits
+ for his request on the slow file to be fulfilled.
+
+ Finally, change the sourcecode to use
+ `MHD_USE_THREAD_PER_CONNECTION' when the daemon is started and try
+ again.
+
+ * Did you succeed in implementing the clock exercise yet? This time,
+ let the server save the program's start time `t' and implement a
+ response simulating a countdown that reaches 0 at `t+60'.
+ Returning a message saying on which point the countdown is, the
+ response should ultimately be to reply "Done" if the program has
+ been running long enough,
+
+ An unofficial, but widely understood, response header line is
+ `Refresh: DELAY; url=URL' with the uppercase words substituted to
+ tell the client it should request the given resource after the
+ given delay again. Improve your program in that the browser (any
+ modern browser should work) automatically reconnects and asks for
+ the status again every 5 seconds or so. The URL would have to be
+ composed so that it begins with "http://", followed by the _URI_
+ the server is reachable from the client's point of view.
+
+ Maybe you want also to visualize the countdown as a status bar by
+ creating a `<table>' consisting of one row and `n' columns whose
+ fields contain small images of either a red or a green light.

+
+5 Supporting basic authentication
+*********************************
+
+With the small exception of IP address based access control, requests
+from all connecting clients where served equally until now. This
+chapter discusses a first method of client's authentication and its
+limits.
+
+ A very simple approach feasible with the means already discussed
+would be to expect the password in the _URI_ string before granting
+access to the secured areas. The password could be separated from the
+actual resource identifier by a certain character, thus the request
+line might look like
+GET /picture.png?mypassword
+ In the rare situation where the client is customized enough and the
+connection occurs through secured lines (e.g., a embedded device
+directly attached to another via wire) and where the ability to embedd
+a password in the URI or to pass on a URI with a password are desired,
+this can be a reasonable choice.
+
+ But when it is assumed that the user connecting does so with an
+ordinary Internet browser, this implementation brings some problems
+about. For example, the URI including the password stays in the address
+field or at least in the history of the browser for anybody near enough
+to see. It will also be inconvenient to add the password manually to
+any new URI when the browser does not know how to compose this
+automatically.
+
+ At least the convenience issue can be addressed by employing the
+simplest built-in password facilities of HTTP compliant browsers, hence
+we want to start there. It will however turn out to have still severe
+weaknesses in terms of security which need consideration.
+
+ Before we will start implementing _Basic Authentication_ as
+described in _RFC 2617_, we should finally abandon the bad practice of
+responding every request the first time our callback is called for a
+given connection. This is becoming more important now because the
+client and the server will have to talk in a more bi-directional way
+than before to
+
+ But how can we tell whether the callback has been called before for
+the particular connection? Initially, the pointer this parameter
+references is set by _MHD_ in the callback. But it will also be
+"remembered" on the next call (for the same connection). Thus, we will
+generate no response until the parameter is non-null--implying the
+callback was called before at least once. We do not need to share
+information between different calls of the callback, so we can set the
+parameter to any adress that is assured to be not null. The pointer to
+the `connection' structure will be pointing to a legal address, so we
+take this.
+
+ The first time `answer_to_connection' is called, we will not even
+look at the headers.
+
+static int
+answer_to_connection (void *cls, struct MHD_Connection *connection,
+ const char *url, const char *method, const char *version,
+ const char *upload_data, size_t *upload_data_size,
+ void **con_cls)
+{
+ if (0 != strcmp(method, "GET")) return MHD_NO;
+ if (NULL == *con_cls) {*con_cls = connection; return MHD_YES;}
+
+ ...
+ /* else respond accordingly */
+ ...
+}
+ Note how we lop off the connection on the first condition (no "GET"
+request), but return asking for more on the other one with `MHD_YES'.
+With this minor change, we can proceed to implement the actual
+authentication process.
+
+Request for authentication
+==========================
+
+Let us assume we had only files not intended to be handed out without
+the correct username/password, so every "GET" request will be
+challenged. _RFC 2617_ describes how the server shall ask for
+authentication by adding a _WWW-Authenticate_ response header with the
+name of the _realm_ protected. MHD can generate and queue such a
+failure response for you using the `MHD_queue_basic_auth_fail_response'
+API. The only thing you need to do is construct a response with the
+error page to be shown to the user if he aborts basic authentication.
+But first, you should check if the proper credentials were already
+supplied using the `MHD_basic_auth_get_username_password' call.
+
+ Your code would then look like this:
+static int
+answer_to_connection (void *cls, struct MHD_Connection *connection,
+ const char *url, const char *method,
+ const char *version, const char *upload_data,
+ size_t *upload_data_size, void **con_cls)
+{
+ char *user;
+ char *pass;
+ int fail;
+ struct MHD_Response *response;
+
+ if (0 != strcmp (method, MHD_HTTP_METHOD_GET))
+ return MHD_NO;
+ if (NULL == *con_cls)
+ {
+ *con_cls = connection;
+ return MHD_YES;
+ }
+ pass = NULL;
+ user = MHD_basic_auth_get_username_password (connection, &pass);
+ fail = ( (user == NULL) ||
+ (0 != strcmp (user, "root")) ||
+ (0 != strcmp (pass, "pa$$w0rd") ) );
+ if (user != NULL) free (user);
+ if (pass != NULL) free (pass);
+ if (fail)
+ {
+ const char *page = "<html><body>Go away.</body></html>";
+ response =
+ MHD_create_response_from_buffer (strlen (page), (void *) page,
+ MHD_RESPMEM_PERSISTENT);
+ ret = MHD_queue_basic_auth_fail_response (connection,
+ "my realm",
+ response);
+ }
+ else
+ {
+ const char *page = "<html><body>A secret.</body></html>";
+ response =
+ MHD_create_response_from_buffer (strlen (page), (void *) page,
+ MHD_RESPMEM_PERSISTENT);
+ ret = MHD_queue_response (connection, MHD_HTTP_OK, response);
+ }
+ MHD_destroy_response (response);
+ return ret;
+}
+
+ See the `examples' directory for the complete example file.
+
+Remarks
+=======
+
+For a proper server, the conditional statements leading to a return of
+`MHD_NO' should yield a response with a more precise status code
+instead of silently closing the connection. For example, failures of
+memory allocation are best reported as _internal server error_ and
+unexpected authentication methods as _400 bad request_.
+
+Exercises
+=========
+
+ * Make the server respond to wrong credentials (but otherwise
+ well-formed requests) with the recommended _401 unauthorized_
+ status code. If the client still does not authenticate correctly
+ within the same connection, close it and store the client's IP
+ address for a certain time. (It is OK to check for expiration not
+ until the main thread wakes up again on the next connection.) If
+ the client fails authenticating three times during this period,
+ add it to another list for which the `AcceptPolicyCallback'
+ function denies connection (temporally).
+
+ * With the network utility `netcat' connect and log the response of
+ a "GET" request as you did in the exercise of the first example,
+ this time to a file. Now stop the server and let _netcat_ listen
+ on the same port the server used to listen on and have it fake
+ being the proper server by giving the file's content as the
+ response (e.g. `cat log | nc -l -p 8888'). Pretending to think
+ your were connecting to the actual server, browse to the
+ eavesdropper and give the correct credentials.
+
+ Copy and paste the encoded string you see in `netcat''s output to
+ some of the Base64 decode tools available online and see how both
+ the user's name and password could be completely restored.

+6 Processing POST data
+**********************
+
+The previous chapters already have demonstrated a variety of
+possibilities to send information to the HTTP server, but it is not
+recommended that the _GET_ method is used to alter the way the server
+operates. To induce changes on the server, the _POST_ method is
+preferred over and is much more powerful than _GET_ and will be
+introduced in this chapter.
+
+ We are going to write an application that asks for the visitor's
+name and, after the user has posted it, composes an individual response
+text. Even though it was not mandatory to use the _POST_ method here,
+as there is no permanent change caused by the POST, it is an
+illustrative example on how to share data between different functions
+for the same connection. Furthermore, the reader should be able to
+extend it easily.
+
+GET request
+===========
+
+When the first _GET_ request arrives, the server shall respond with a
+HTML page containing an edit field for the name.
+
+const char* askpage = "<html><body>\
+ What's your name, Sir?<br>\
+ <form action=\"/namepost\" method=\"post\">\
+ <input name=\"name\" type=\"text\"\
+ <input type=\"submit\" value=\" Send \"></form>\
+ </body></html>";
+ The `action' entry is the _URI_ to be called by the browser when
+posting, and the `name' will be used later to be sure it is the
+editbox's content that has been posted.
+
+ We also prepare the answer page, where the name is to be filled in
+later, and an error page as the response for anything but proper _GET_
+and _POST_ requests:
+
+const char* greatingpage="<html><body><h1>Welcome, %s!</center></h1></body></html>";
+
+const char* errorpage="<html><body>This doesn't seem to be right.</body></html>";
+ Whenever we need to send a page, we use an extra function `int
+send_page(struct MHD_Connection *connection, const char* page)' for
+this, which does not contain anything new and whose implementation is
+therefore not discussed further in the tutorial.
+
+POST request
+============
+
+Posted data can be of arbitrary and considerable size; for example, if
+a user uploads a big image to the server. Similar to the case of the
+header fields, there may also be different streams of posted data, such
+as one containing the text of an editbox and another the state of a
+button. Likewise, we will have to register an iterator function that
+is going to be called maybe several times not only if there are
+different POSTs but also if one POST has only been received partly yet
+and needs processing before another chunk can be received.
+
+ Such an iterator function is called by a _postprocessor_, which must
+be created upon arriving of the post request. We want the iterator
+function to read the first post data which is tagged `name' and to
+create an individual greeting string based on the template and the name.
+But in order to pass this string to other functions and still be able
+to differentiate different connections, we must first define a
+structure to share the information, holding the most import entries.
+
+struct connection_info_struct
+{
+ int connectiontype;
+ char *answerstring;
+ struct MHD_PostProcessor *postprocessor;
+};
+ With these information available to the iterator function, it is able
+to fulfill its task. Once it has composed the greeting string, it
+returns `MHD_NO' to inform the post processor that it does not need to
+be called again. Note that this function does not handle processing of
+data for the same `key'. If we were to expect that the name will be
+posted in several chunks, we had to expand the namestring dynamically
+as additional parts of it with the same `key' came in. But in this
+example, the name is assumed to fit entirely inside one single packet.
+
+static int
+iterate_post (void *coninfo_cls, enum MHD_ValueKind kind, const char *key,
+ const char *filename, const char *content_type,
+ const char *transfer_encoding, const char *data,
+ uint64_t off, size_t size)
+{
+ struct connection_info_struct *con_info = coninfo_cls;
+
+ if (0 == strcmp (key, "name"))
+ {
+ if ((size > 0) && (size <= MAXNAMESIZE))
+ {
+ char *answerstring;
+ answerstring = malloc (MAXANSWERSIZE);
+ if (!answerstring) return MHD_NO;
+
+ snprintf (answerstring, MAXANSWERSIZE, greatingpage, data);
+ con_info->answerstring = answerstring;
+ }
+ else con_info->answerstring = NULL;
+
+ return MHD_NO;
+ }
+
+ return MHD_YES;
+}
+ Once a connection has been established, it can be terminated for many
+reasons. As these reasons include unexpected events, we have to
+register another function that cleans up any resources that might have
+been allocated for that connection by us, namely the post processor and
+the greetings string. This cleanup function must take into account that
+it will also be called for finished requests other than _POST_ requests.
+
+void request_completed (void *cls, struct MHD_Connection *connection,
+ void **con_cls,
+ enum MHD_RequestTerminationCode toe)
+{
+ struct connection_info_struct *con_info = *con_cls;
+
+ if (NULL == con_info) return;
+ if (con_info->connectiontype == POST)
+ {
+ MHD_destroy_post_processor (con_info->postprocessor);
+ if (con_info->answerstring) free (con_info->answerstring);
+ }
+
+ free (con_info);
+ *con_cls = NULL;
+}
+ _GNU libmicrohttpd_ is informed that it shall call the above function
+when the daemon is started in the main function.
+
+...
+daemon = MHD_start_daemon (MHD_USE_SELECT_INTERNALLY, PORT, NULL, NULL,
+ &answer_to_connection, NULL,
+ MHD_OPTION_NOTIFY_COMPLETED, &request_completed, NULL,
+ MHD_OPTION_END);
+...
+
+Request handling
+================
+
+With all other functions prepared, we can now discuss the actual
+request handling.
+
+ On the first iteration for a new request, we start by allocating a
+new instance of a `struct connection_info_struct' structure, which will
+store all necessary information for later iterations and other
+functions.
+
+static int
+answer_to_connection (void *cls, struct MHD_Connection *connection,
+ const char *url,
+ const char *method, const char *version,
+ const char *upload_data,
+ size_t *upload_data_size, void **con_cls)
+{
+ if(NULL == *con_cls)
+ {
+ struct connection_info_struct *con_info;
+
+ con_info = malloc (sizeof (struct connection_info_struct));
+ if (NULL == con_info) return MHD_NO;
+ con_info->answerstring = NULL;
+ If the new request is a _POST_, the postprocessor must be created now.
+In addition, the type of the request is stored for convenience.
+ if (0 == strcmp (method, "POST"))
+ {
+ con_info->postprocessor
+ = MHD_create_post_processor (connection, POSTBUFFERSIZE,
+ iterate_post, (void*) con_info);
+
+ if (NULL == con_info->postprocessor)
+ {
+ free (con_info);
+ return MHD_NO;
+ }
+ con_info->connectiontype = POST;
+ }
+ else con_info->connectiontype = GET;
+ The address of our structure will both serve as the indicator for
+successive iterations and to remember the particular details about the
+connection.
+ *con_cls = (void*) con_info;
+ return MHD_YES;
+ }
+ The rest of the function will not be executed on the first iteration.
+A _GET_ request is easily satisfied by sending the question form.
+ if (0 == strcmp (method, "GET"))
+ {
+ return send_page (connection, askpage);
+ }
+ In case of _POST_, we invoke the post processor for as long as data
+keeps incoming, setting `*upload_data_size' to zero in order to
+indicate that we have processed--or at least have considered--all of it.
+ if (0 == strcmp (method, "POST"))
+ {
+ struct connection_info_struct *con_info = *con_cls;
+
+ if (*upload_data_size != 0)
+ {
+ MHD_post_process (con_info->postprocessor, upload_data,
+ *upload_data_size);
+ *upload_data_size = 0;
+
+ return MHD_YES;
+ }
+ else if (NULL != con_info->answerstring)
+ return send_page (connection, con_info->answerstring);
+ }
+ Finally, if they are neither _GET_ nor _POST_ requests, the error page
+is returned.
+ return send_page(connection, errorpage);
+}
+ These were the important parts of the program `simplepost.c'.

+7 Improved processing of POST data
+**********************************
+
+The previous chapter introduced a way to upload data to the server, but
+the developed example program has some shortcomings, such as not being
+able to handle larger chunks of data. In this chapter, we are going to
+discuss a more advanced server program that allows clients to upload a
+file in order to have it stored on the server's filesystem. The server
+shall also watch and limit the number of clients concurrently
+uploading, responding with a proper busy message if necessary.
+
+Prepared answers
+================
+
+We choose to operate the server with the `SELECT_INTERNALLY' method.
+This makes it easier to synchronize the global states at the cost of
+possible delays for other connections if the processing of a request is
+too slow. One of these variables that needs to be shared for all
+connections is the total number of clients that are uploading.
+
+#define MAXCLIENTS 2
+static unsigned int nr_of_uploading_clients = 0;
+ If there are too many clients uploading, we want the server to respond
+to all requests with a busy message.
+const char* busypage =
+ "<html><body>This server is busy, please try again later.</body></html>";
+ Otherwise, the server will send a _form_ that informs the user of the
+current number of uploading clients, and ask her to pick a file on her
+local filesystem which is to be uploaded.
+const char* askpage = "<html><body>\n\
+ Upload a file, please!<br>\n\
+ There are %u clients uploading at the moment.<br>\n\
+ <form action=\"/filepost\" method=\"post\" \
+ enctype=\"multipart/form-data\">\n\
+ <input name=\"file\" type=\"file\">\n\
+ <input type=\"submit\" value=\" Send \"></form>\n\
+ </body></html>";
+ If the upload has succeeded, the server will respond with a message
+saying so.
+const char* completepage = "<html><body>The upload has been completed.</body></html>";
+ We want the server to report internal errors, such as memory shortage
+or file access problems, adequately.
+const char* servererrorpage
+ = "<html><body>An internal server error has occured.</body></html>";
+const char* fileexistspage
+ = "<html><body>This file already exists.</body></html>";
+ It would be tolerable to send all these responses undifferentiated
+with a `200 HTTP_OK' status code but in order to improve the `HTTP'
+conformance of our server a bit, we extend the `send_page' function so
+that it accepts individual status codes.
+
+static int
+send_page (struct MHD_Connection *connection,
+ const char* page, int status_code)
+{
+ int ret;
+ struct MHD_Response *response;
+
+ response = MHD_create_response_from_buffer (strlen (page), (void*) page,
+ MHD_RESPMEM_MUST_COPY);
+ if (!response) return MHD_NO;
+
+ ret = MHD_queue_response (connection, status_code, response);
+ MHD_destroy_response (response);
+
+ return ret;
+}
+ Note how we ask _MHD_ to make its own copy of the message data. The
+reason behind this will become clear later.
+
+Connection cycle
+================
+
+The decision whether the server is busy or not is made right at the
+beginning of the connection. To do that at this stage is especially
+important for _POST_ requests because if no response is queued at this
+point, and `MHD_YES' returned, _MHD_ will not sent any queued messages
+until a postprocessor has been created and the post iterator is called
+at least once.
+
+static int
+answer_to_connection (void *cls, struct MHD_Connection *connection,
+ const char *url,
+ const char *method, const char *version,
+ const char *upload_data,
+ size_t *upload_data_size, void **con_cls)
+{
+ if (NULL == *con_cls)
+ {
+ struct connection_info_struct *con_info;
+
+ if (nr_of_uploading_clients >= MAXCLIENTS)
+ return send_page(connection, busypage, MHD_HTTP_SERVICE_UNAVAILABLE);
+ If the server is not busy, the `connection_info' structure is
+initialized as usual, with the addition of a filepointer for each
+connection.
+
+ con_info = malloc (sizeof (struct connection_info_struct));
+ if (NULL == con_info) return MHD_NO;
+ con_info->fp = 0;
+
+ if (0 == strcmp (method, "POST"))
+ {
+ ...
+ }
+ else con_info->connectiontype = GET;
+
+ *con_cls = (void*) con_info;
+
+ return MHD_YES;
+ }
+ For _POST_ requests, the postprocessor is created and we register a
+new uploading client. From this point on, there are many possible
+places for errors to occur that make it necessary to interrupt the
+uploading process. We need a means of having the proper response
+message ready at all times. Therefore, the `connection_info' structure
+is extended to hold the most current response message so that whenever
+a response is sent, the client will get the most informative message.
+Here, the structure is initialized to "no error".
+ if (0 == strcmp (method, "POST"))
+ {
+ con_info->postprocessor
+ = MHD_create_post_processor (connection, POSTBUFFERSIZE,
+ iterate_post, (void*) con_info);
+
+ if (NULL == con_info->postprocessor)
+ {
+ free (con_info);
+ return MHD_NO;
+ }
+
+ nr_of_uploading_clients++;
+
+ con_info->connectiontype = POST;
+ con_info->answercode = MHD_HTTP_OK;
+ con_info->answerstring = completepage;
+ }
+ else con_info->connectiontype = GET;
+ If the connection handler is called for the second time, _GET_
+requests will be answered with the _form_. We can keep the buffer under
+function scope, because we asked _MHD_ to make its own copy of it for
+as long as it is needed.
+ if (0 == strcmp (method, "GET"))
+ {
+ int ret;
+ char buffer[1024];
+
+ sprintf (buffer, askpage, nr_of_uploading_clients);
+ return send_page (connection, buffer, MHD_HTTP_OK);
+ }
+ The rest of the `answer_to_connection' function is very similar to the
+`simplepost.c' example, except the more flexible content of the
+responses. The _POST_ data is processed until there is none left and
+the execution falls through to return an error page if the connection
+constituted no expected request method.
+ if (0 == strcmp (method, "POST"))
+ {
+ struct connection_info_struct *con_info = *con_cls;
+
+ if (0 != *upload_data_size)
+ {
+ MHD_post_process (con_info->postprocessor,
+ upload_data, *upload_data_size);
+ *upload_data_size = 0;
+
+ return MHD_YES;
+ }
+ else
+ return send_page (connection, con_info->answerstring,
+ con_info->answercode);
+ }
+
+ return send_page(connection, errorpage, MHD_HTTP_BAD_REQUEST);
+}
+
+Storing to data
+===============
+
+Unlike the `simplepost.c' example, here it is to be expected that post
+iterator will be called several times now. This means that for any
+given connection (there might be several concurrent of them) the posted
+data has to be written to the correct file. That is why we store a file
+handle in every `connection_info', so that the it is preserved between
+successive iterations.
+static int
+iterate_post (void *coninfo_cls, enum MHD_ValueKind kind,
+ const char *key,
+ const char *filename, const char *content_type,
+ const char *transfer_encoding, const char *data,
+ uint64_t off, size_t size)
+{
+ struct connection_info_struct *con_info = coninfo_cls;
+ Because the following actions depend heavily on correct file
+processing, which might be error prone, we default to reporting
+internal errors in case anything will go wrong.
+
+con_info->answerstring = servererrorpage;
+con_info->answercode = MHD_HTTP_INTERNAL_SERVER_ERROR;
+ In the "askpage" _form_, we told the client to label its post data
+with the "file" key. Anything else would be an error.
+
+ if (0 != strcmp (key, "file")) return MHD_NO;
+ If the iterator is called for the first time, no file will have been
+opened yet. The `filename' string contains the name of the file
+(without any paths) the user selected on his system. We want to take
+this as the name the file will be stored on the server and make sure no
+file of that name exists (or is being uploaded) before we create one
+(note that the code below technically contains a race between the two
+"fopen" calls, but we will overlook this for portability sake).
+ if (!con_info->fp)
+ {
+ if (NULL != (fp = fopen (filename, "rb")) )
+ {
+ fclose (fp);
+ con_info->answerstring = fileexistspage;
+ con_info->answercode = MHD_HTTP_FORBIDDEN;
+ return MHD_NO;
+ }
+
+ con_info->fp = fopen (filename, "ab");
+ if (!con_info->fp) return MHD_NO;
+ }
+ Occasionally, the iterator function will be called even when there are
+0 new bytes to process. The server only needs to write data to the file
+if there is some.
+if (size > 0)
+ {
+ if (!fwrite (data, size, sizeof(char), con_info->fp))
+ return MHD_NO;
+ }
+ If this point has been reached, everything worked well for this
+iteration and the response can be set to success again. If the upload
+has finished, this iterator function will not be called again.
+ con_info->answerstring = completepage;
+ con_info->answercode = MHD_HTTP_OK;
+
+ return MHD_YES;
+}
+ The new client was registered when the postprocessor was created.
+Likewise, we unregister the client on destroying the postprocessor when
+the request is completed.
+void request_completed (void *cls, struct MHD_Connection *connection,
+ void **con_cls,
+ enum MHD_RequestTerminationCode toe)
+{
+ struct connection_info_struct *con_info = *con_cls;
+
+ if (NULL == con_info) return;
+
+ if (con_info->connectiontype == POST)
+ {
+ if (NULL != con_info->postprocessor)
+ {
+ MHD_destroy_post_processor (con_info->postprocessor);
+ nr_of_uploading_clients--;
+ }
+
+ if (con_info->fp) fclose (con_info->fp);
+ }
+
+ free (con_info);
+ *con_cls = NULL;
+}
+ This is essentially the whole example `largepost.c'.
+
+Remarks
+=======
+
+Now that the clients are able to create files on the server, security
+aspects are becoming even more important than before. Aside from proper
+client authentication, the server should always make sure explicitly
+that no files will be created outside of a dedicated upload directory.
+In particular, filenames must be checked to not contain strings like
+"../".

+
+8 Session management
+********************
+
+This chapter discusses how one should manage sessions, that is, share
+state between multiple HTTP requests from the same user. We use a
+simple example where the user submits multiple forms and the server is
+supposed to accumulate state from all of these forms. Naturally, as
+this is a network protocol, our session mechanism must support having
+many users with many concurrent sessions at the same time.
+
+ In order to track users, we use a simple session cookie. A session
+cookie expires when the user closes the browser. Changing from session
+cookies to persistent cookies only requires adding an expiration time
+to the cookie. The server creates a fresh session cookie whenever a
+request without a cookie is received, or if the supplied session cookie
+is not known to the server.
+
+Looking up the cookie
+=====================
+
+Since MHD parses the HTTP cookie header for us, looking up an existing
+cookie is straightforward:
+
+FIXME.
+
+ Here, FIXME is the name we chose for our session cookie.
+
+Setting the cookie header
+=========================
+
+MHD requires the user to provide the full cookie format string in order
+to set cookies. In order to generate a unique cookie, our example
+creates a random 64-character text string to be used as the value of
+the cookie:
+
+FIXME.
+
+ Given this cookie value, we can then set the cookie header in our
+HTTP response as follows:
+
+FIXME.
+
+Remark: Session expiration
+==========================
+
+It is of course possible that clients stop their interaction with the
+server at any time. In order to avoid using too much storage, the
+server must thus discard inactive sessions at some point. Our example
+implements this by discarding inactive sessions after a certain amount
+of time. Alternatively, the implementation may limit the total number
+of active sessions. Which bounds are used for idle sessions or the
+total number of sessions obviously depends largely on the type of the
+application and available server resources.
+
+Example code
+============
+
+A sample application implementing a website with multiple forms (which
+are dynamically created using values from previous POST requests from
+the same session) is available as the example `sessions.c'.
+
+ Note that the example uses a simple, $O(n)$ linked list traversal to
+look up sessions and to expire old sessions. Using a hash table and a
+heap would be more appropriate if a large number of concurrent sessions
+is expected.
+
+Remarks
+=======
+
+Naturally, it is quite conceivable to store session data in a database
+instead of in memory. Still, having mechanisms to expire data
+associated with long-time idle sessions (where the business process has
+still not finished) is likely a good idea.
+

+
+9 Adding a layer of security
+****************************
+
+We left the basic authentication chapter with the unsatisfactory
+conclusion that any traffic, including the credentials, could be
+intercepted by anyone between the browser client and the server.
+Protecting the data while it is sent over unsecured lines will be the
+goal of this chapter.
+
+ Since version 0.4, the _MHD_ library includes support for encrypting
+the traffic by employing SSL/TSL. If _GNU libmicrohttpd_ has been
+configured to support these, encryption and decryption can be applied
+transparently on the data being sent, with only minimal changes to the
+actual source code of the example.
+
+Preparation
+===========
+
+First, a private key for the server will be generated. With this key,
+the server will later be able to authenticate itself to the
+client--preventing anyone else from stealing the password by faking its
+identity. The _OpenSSL_ suite, which is available on many operating
+systems, can generate such a key. For the scope of this tutorial, we
+will be content with a 1024 bit key:
+> openssl genrsa -out server.key 1024
+ In addition to the key, a certificate describing the server in human
+readable tokens is also needed. This certificate will be attested with
+our aforementioned key. In this way, we obtain a self-signed
+certificate, valid for one year.
+
+> openssl req -days 365 -out server.pem -new -x509 -key server.key
+ To avoid unnecessary error messages in the browser, the certificate
+needs to have a name that matches the _URI_, for example, "localhost"
+or the domain. If you plan to have a publicly reachable server, you
+will need to ask a trusted third party, called _Certificate Authority_,
+or _CA_, to attest the certificate for you. This way, any visitor can
+make sure the server's identity is real.
+
+ Whether the server's certificate is signed by us or a third party,
+once it has been accepted by the client, both sides will be
+communicating over encrypted channels. From this point on, it is the
+client's turn to authenticate itself. But this has already been
+implemented in the basic authentication scheme.
+
+Changing the source code
+========================
+
+We merely have to extend the server program so that it loads the two
+files into memory,
+
+int
+main ()
+{
+ struct MHD_Daemon *daemon;
+ char *key_pem;
+ char *cert_pem;
+
+ key_pem = load_file (SERVERKEYFILE);
+ cert_pem = load_file (SERVERCERTFILE);
+
+ if ((key_pem == NULL) || (cert_pem == NULL))
+ {
+ printf ("The key/certificate files could not be read.\n");
+ return 1;
+ }
+ and then we point the _MHD_ daemon to it upon initalization.
+
+ daemon = MHD_start_daemon (MHD_USE_SELECT_INTERNALLY | MHD_USE_SSL,
+ PORT, NULL, NULL,
+ &answer_to_connection, NULL,
+ MHD_OPTION_HTTPS_MEM_KEY, key_pem,
+ MHD_OPTION_HTTPS_MEM_CERT, cert_pem,
+ MHD_OPTION_END);
+
+ if (NULL == daemon)
+ {
+ printf ("%s\n", cert_pem);
+
+ free (key_pem);
+ free (cert_pem);
+
+ return 1;
+ }
+ The rest consists of little new besides some additional memory
+cleanups.
+
+ getchar ();
+
+ MHD_stop_daemon (daemon);
+ free (key_pem);
+ free (cert_pem);
+
+ return 0;
+}
+ The rather unexciting file loader can be found in the complete example
+`tlsauthentication.c'.
+
+Remarks
+=======
+
+ * While the standard _HTTP_ port is 80, it is 443 for _HTTPS_. The
+ common internet browsers assume standard _HTTP_ if they are asked
+ to access other ports than these. Therefore, you will have to type
+ `https://localhost:8888' explicitly when you test the example, or
+ the browser will not know how to handle the answer properly.
+
+ * The remaining weak point is the question how the server will be
+ trusted initially. Either a _CA_ signs the certificate or the
+ client obtains the key over secure means. Anyway, the clients have
+ to be aware (or configured) that they should not accept
+ certificates of unknown origin.
+
+ * The introduced method of certificates makes it mandatory to set an
+ expiration date--making it less feasible to hardcode certificates
+ in embedded devices.
+
+ * The cryptographic facilities consume memory space and computing
+ time. For this reason, websites usually consists both of
+ uncritically _HTTP_ parts and secured _HTTPS_.
+
+
+Client authentication
+=====================
+
+You can also use MHD to authenticate the client via SSL/TLS certificates
+(as an alternative to using the password-based Basic or Digest
+authentication). To do this, you will need to link your application
+against _gnutls_. Next, when you start the MHD daemon, you must
+specify the root CA that you're willing to trust:
+ daemon = MHD_start_daemon (MHD_USE_SELECT_INTERNALLY | MHD_USE_SSL,
+ PORT, NULL, NULL,
+ &answer_to_connection, NULL,
+ MHD_OPTION_HTTPS_MEM_KEY, key_pem,
+ MHD_OPTION_HTTPS_MEM_CERT, cert_pem,
+ MHD_OPTION_HTTPS_MEM_TRUST, root_ca_pem,
+ MHD_OPTION_END);
+
+ With this, you can then obtain client certificates for each session.
+In order to obtain the identity of the client, you first need to obtain
+the raw GnuTLS session handle from _MHD_ using
+`MHD_get_connection_info'.
+
+#include <gnutls/gnutls.h>
+#include <gnutls/x509.h>
+
+gnutls_session_t tls_session;
+union MHD_ConnectionInfo *ci;
+
+ci = MHD_get_connection_info (connection,
+ MHD_CONNECTION_INFO_GNUTLS_SESSION);
+tls_session = ci->tls_session;
+
+ You can then extract the client certificate:
+
+/**
+ * Get the client's certificate
+ *
+ * @param tls_session the TLS session
+ * @return NULL if no valid client certificate could be found, a pointer

+
+Using TLS Server Name Indication (SNI)
+======================================
+
+SNI enables hosting multiple domains under one IP address with TLS. So
+SNI is the TLS-equivalent of virtual hosting. To use SNI with MHD, you
+need at least GnuTLS 3.0. The main change compared to the simple
+hosting of one domain is that you need to provide a callback instead of
+the key and certificate. For example, when you start the MHD daemon,
+you could do this:
+ daemon = MHD_start_daemon (MHD_USE_SELECT_INTERNALLY | MHD_USE_SSL,
+ PORT, NULL, NULL,
+ &answer_to_connection, NULL,
+ MHD_OPTION_HTTPS_CERT_CALLBACK, &sni_callback,
+ MHD_OPTION_END);
+ Here, `sni_callback' is the name of a function that you will have to
+implement to retrieve the X.509 certificate for an incoming connection.
+The callback has type `gnutls_certificate_retrieve_function2' and is
+documented in the GnuTLS API for the
+`gnutls_certificate_set_retrieve_function2' as follows:
+
+ -- Function Pointer: int *gnutls_certificate_retrieve_function2
+ (gnutls_session_t, const gnutls_datum_t* req_ca_dn, int
+ nreqs, const gnutls_pk_algorithm_t* pk_algos, int
+ pk_algos_length, gnutls_pcert_st** pcert, unsigned int
+ *pcert_length, gnutls_privkey_t * pkey)
+ REQ_CA_CERT
+ is only used in X.509 certificates. Contains a list with the
+ CA names that the server considers trusted. Normally we
+ should send a certificate that is signed by one of these CAs.
+ These names are DER encoded. To get a more meaningful value
+ use the function `gnutls_x509_rdn_get()'.
+
+ PK_ALGOS
+ contains a list with server’s acceptable signature
+ algorithms. The certificate returned should support the
+ server’s given algorithms.
+
+ PCERT
+ should contain a single certificate and public or a list of
+ them.
+
+ PCERT_LENGTH
+ is the size of the previous list.
+
+ PKEY
+ is the private key.
+
+ A possible implementation of this callback would look like this:
+
+struct Hosts
+{
+ struct Hosts *next;
+ const char *hostname;
+ gnutls_pcert_st pcrt;
+ gnutls_privkey_t key;
+};
+
+static struct Hosts *hosts;
+
+int
+sni_callback (gnutls_session_t session,
+ const gnutls_datum_t* req_ca_dn,
+ int nreqs,
+ const gnutls_pk_algorithm_t* pk_algos,
+ int pk_algos_length,
+ gnutls_pcert_st** pcert,
+ unsigned int *pcert_length,
+ gnutls_privkey_t * pkey)
+{
+ char name[256];
+ size_t name_len;
+ struct Hosts *host;
+ unsigned int type;
+
+ name_len = sizeof (name);
+ if (GNUTLS_E_SUCCESS !=
+ gnutls_server_name_get (session,
+ name,
+ &name_len,
+ &type,
+ 0 /* index */))
+ return -1;
+ for (host = hosts; NULL != host; host = host->next)
+ if (0 == strncmp (name, host->hostname, name_len))
+ break;
+ if (NULL == host)
+ {
+ fprintf (stderr,
+ "Need certificate for %.*s\n",
+ (int) name_len,
+ name);
+ return -1;
+ }
+ fprintf (stderr,
+ "Returning certificate for %.*s\n",
+ (int) name_len,
+ name);
+ *pkey = host->key;
+ *pcert_length = 1;
+ *pcert = &host->pcrt;
+ return 0;
+}
+
+ Note that MHD cannot offer passing a closure or any other additional
+information to this callback, as the GnuTLS API unfortunately does not
+permit this at this point.
+
+ The `hosts' list can be initialized by loading the private keys and
+X.509 certificats from disk as follows:
+
+static void
+load_keys(const char *hostname,
+ const char *CERT_FILE,
+ const char *KEY_FILE)
+{
+ int ret;
+ gnutls_datum_t data;
+ struct Hosts *host;
+
+ host = malloc (sizeof (struct Hosts));
+ host->hostname = hostname;
+ host->next = hosts;
+ hosts = host;
+
+ ret = gnutls_load_file (CERT_FILE, &data);
+ if (ret < 0)
+ {
+ fprintf (stderr,
+ "*** Error loading certificate file %s.\n",
+ CERT_FILE);
+ exit(1);
+ }
+ ret =
+ gnutls_pcert_import_x509_raw (&host->pcrt, &data, GNUTLS_X509_FMT_PEM,
+ 0);
+ if (ret < 0)
+ {
+ fprintf(stderr,
+ "*** Error loading certificate file: %s\n",
+ gnutls_strerror (ret));
+ exit(1);
+ }
+ gnutls_free (data.data);
+
+ ret = gnutls_load_file (KEY_FILE, &data);
+ if (ret < 0)
+ {
+ fprintf (stderr,
+ "*** Error loading key file %s.\n",
+ KEY_FILE);
+ exit(1);
+ }
+
+ gnutls_privkey_init (&host->key);
+ ret =
+ gnutls_privkey_import_x509_raw (host->key,
+ &data, GNUTLS_X509_FMT_PEM,
+ NULL, 0);
+ if (ret < 0)
+ {
+ fprintf (stderr,
+ "*** Error loading key file: %s\n",
+ gnutls_strerror (ret));
+ exit(1);
+ }
+ gnutls_free (data.data);
+}
+
+ The code above was largely lifted from GnuTLS. You can find other
+methods for initializing certificates and keys in the GnuTLS manual and
+source code.

+ Version 1.3, 3 November 2008
+
+ Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
+ `http://fsf.org/'
+
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ 0. PREAMBLE
+
+ The purpose of this License is to make a manual, textbook, or other
+ functional and useful document "free" in the sense of freedom: to
+ assure everyone the effective freedom to copy and redistribute it,
+ with or without modifying it, either commercially or
+ noncommercially. Secondarily, this License preserves for the
+ author and publisher a way to get credit for their work, while not
+ being considered responsible for modifications made by others.
+
+ This License is a kind of "copyleft", which means that derivative
+ works of the document must themselves be free in the same sense.
+ It complements the GNU General Public License, which is a copyleft
+ license designed for free software.
+
+ We have designed this License in order to use it for manuals for
+ free software, because free software needs free documentation: a
+ free program should come with manuals providing the same freedoms
+ that the software does. But this License is not limited to
+ software manuals; it can be used for any textual work, regardless
+ of subject matter or whether it is published as a printed book.
+ We recommend this License principally for works whose purpose is
+ instruction or reference.
+
+ 1. APPLICABILITY AND DEFINITIONS
+
+ This License applies to any manual or other work, in any medium,
+ that contains a notice placed by the copyright holder saying it
+ can be distributed under the terms of this License. Such a notice
+ grants a world-wide, royalty-free license, unlimited in duration,
+ to use that work under the conditions stated herein. The
+ "Document", below, refers to any such manual or work. Any member
+ of the public is a licensee, and is addressed as "you". You
+ accept the license if you copy, modify or distribute the work in a
+ way requiring permission under copyright law.
+
+ A "Modified Version" of the Document means any work containing the
+ Document or a portion of it, either copied verbatim, or with
+ modifications and/or translated into another language.
+
+ A "Secondary Section" is a named appendix or a front-matter section
+ of the Document that deals exclusively with the relationship of the
+ publishers or authors of the Document to the Document's overall
+ subject (or to related matters) and contains nothing that could
+ fall directly within that overall subject. (Thus, if the Document
+ is in part a textbook of mathematics, a Secondary Section may not
+ explain any mathematics.) The relationship could be a matter of
+ historical connection with the subject or with related matters, or
+ of legal, commercial, philosophical, ethical or political position
+ regarding them.
+
+ The "Invariant Sections" are certain Secondary Sections whose
+ titles are designated, as being those of Invariant Sections, in
+ the notice that says that the Document is released under this
+ License. If a section does not fit the above definition of
+ Secondary then it is not allowed to be designated as Invariant.
+ The Document may contain zero Invariant Sections. If the Document
+ does not identify any Invariant Sections then there are none.
+
+ The "Cover Texts" are certain short passages of text that are
+ listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+ that says that the Document is released under this License. A
+ Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+ be at most 25 words.
+
+ A "Transparent" copy of the Document means a machine-readable copy,
+ represented in a format whose specification is available to the
+ general public, that is suitable for revising the document
+ straightforwardly with generic text editors or (for images
+ composed of pixels) generic paint programs or (for drawings) some
+ widely available drawing editor, and that is suitable for input to
+ text formatters or for automatic translation to a variety of
+ formats suitable for input to text formatters. A copy made in an
+ otherwise Transparent file format whose markup, or absence of
+ markup, has been arranged to thwart or discourage subsequent
+ modification by readers is not Transparent. An image format is
+ not Transparent if used for any substantial amount of text. A
+ copy that is not "Transparent" is called "Opaque".
+
+ Examples of suitable formats for Transparent copies include plain
+ ASCII without markup, Texinfo input format, LaTeX input format,
+ SGML or XML using a publicly available DTD, and
+ standard-conforming simple HTML, PostScript or PDF designed for
+ human modification. Examples of transparent image formats include
+ PNG, XCF and JPG. Opaque formats include proprietary formats that
+ can be read and edited only by proprietary word processors, SGML or
+ XML for which the DTD and/or processing tools are not generally
+ available, and the machine-generated HTML, PostScript or PDF
+ produced by some word processors for output purposes only.
+
+ The "Title Page" means, for a printed book, the title page itself,
+ plus such following pages as are needed to hold, legibly, the
+ material this License requires to appear in the title page. For
+ works in formats which do not have any title page as such, "Title
+ Page" means the text near the most prominent appearance of the
+ work's title, preceding the beginning of the body of the text.
+
+ The "publisher" means any person or entity that distributes copies
+ of the Document to the public.
+
+ A section "Entitled XYZ" means a named subunit of the Document
+ whose title either is precisely XYZ or contains XYZ in parentheses
+ following text that translates XYZ in another language. (Here XYZ
+ stands for a specific section name mentioned below, such as
+ "Acknowledgements", "Dedications", "Endorsements", or "History".)
+ To "Preserve the Title" of such a section when you modify the
+ Document means that it remains a section "Entitled XYZ" according
+ to this definition.
+
+ The Document may include Warranty Disclaimers next to the notice
+ which states that this License applies to the Document. These
+ Warranty Disclaimers are considered to be included by reference in
+ this License, but only as regards disclaiming warranties: any other
+ implication that these Warranty Disclaimers may have is void and
+ has no effect on the meaning of this License.
+
+ 2. VERBATIM COPYING
+
+ You may copy and distribute the Document in any medium, either
+ commercially or noncommercially, provided that this License, the
+ copyright notices, and the license notice saying this License
+ applies to the Document are reproduced in all copies, and that you
+ add no other conditions whatsoever to those of this License. You
+ may not use technical measures to obstruct or control the reading
+ or further copying of the copies you make or distribute. However,
+ you may accept compensation in exchange for copies. If you
+ distribute a large enough number of copies you must also follow
+ the conditions in section 3.
+
+ You may also lend copies, under the same conditions stated above,
+ and you may publicly display copies.
+
+ 3. COPYING IN QUANTITY
+
+ If you publish printed copies (or copies in media that commonly
+ have printed covers) of the Document, numbering more than 100, and
+ the Document's license notice requires Cover Texts, you must
+ enclose the copies in covers that carry, clearly and legibly, all
+ these Cover Texts: Front-Cover Texts on the front cover, and
+ Back-Cover Texts on the back cover. Both covers must also clearly
+ and legibly identify you as the publisher of these copies. The
+ front cover must present the full title with all words of the
+ title equally prominent and visible. You may add other material
+ on the covers in addition. Copying with changes limited to the
+ covers, as long as they preserve the title of the Document and
+ satisfy these conditions, can be treated as verbatim copying in
+ other respects.
+
+ If the required texts for either cover are too voluminous to fit
+ legibly, you should put the first ones listed (as many as fit
+ reasonably) on the actual cover, and continue the rest onto
+ adjacent pages.
+
+ If you publish or distribute Opaque copies of the Document
+ numbering more than 100, you must either include a
+ machine-readable Transparent copy along with each Opaque copy, or
+ state in or with each Opaque copy a computer-network location from
+ which the general network-using public has access to download
+ using public-standard network protocols a complete Transparent
+ copy of the Document, free of added material. If you use the
+ latter option, you must take reasonably prudent steps, when you
+ begin distribution of Opaque copies in quantity, to ensure that
+ this Transparent copy will remain thus accessible at the stated
+ location until at least one year after the last time you
+ distribute an Opaque copy (directly or through your agents or
+ retailers) of that edition to the public.
+
+ It is requested, but not required, that you contact the authors of
+ the Document well before redistributing any large number of
+ copies, to give them a chance to provide you with an updated
+ version of the Document.
+
+ 4. MODIFICATIONS
+
+ You may copy and distribute a Modified Version of the Document
+ under the conditions of sections 2 and 3 above, provided that you
+ release the Modified Version under precisely this License, with
+ the Modified Version filling the role of the Document, thus
+ licensing distribution and modification of the Modified Version to
+ whoever possesses a copy of it. In addition, you must do these
+ things in the Modified Version:
+
+ A. Use in the Title Page (and on the covers, if any) a title
+ distinct from that of the Document, and from those of
+ previous versions (which should, if there were any, be listed
+ in the History section of the Document). You may use the
+ same title as a previous version if the original publisher of
+ that version gives permission.
+
+ B. List on the Title Page, as authors, one or more persons or
+ entities responsible for authorship of the modifications in
+ the Modified Version, together with at least five of the
+ principal authors of the Document (all of its principal
+ authors, if it has fewer than five), unless they release you
+ from this requirement.
+
+ C. State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+
+ D. Preserve all the copyright notices of the Document.
+
+ E. Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+
+ F. Include, immediately after the copyright notices, a license
+ notice giving the public permission to use the Modified
+ Version under the terms of this License, in the form shown in
+ the Addendum below.
+
+ G. Preserve in that license notice the full lists of Invariant
+ Sections and required Cover Texts given in the Document's
+ license notice.
+
+ H. Include an unaltered copy of this License.
+
+ I. Preserve the section Entitled "History", Preserve its Title,
+ and add to it an item stating at least the title, year, new
+ authors, and publisher of the Modified Version as given on
+ the Title Page. If there is no section Entitled "History" in
+ the Document, create one stating the title, year, authors,
+ and publisher of the Document as given on its Title Page,
+ then add an item describing the Modified Version as stated in
+ the previous sentence.
+
+ J. Preserve the network location, if any, given in the Document
+ for public access to a Transparent copy of the Document, and
+ likewise the network locations given in the Document for
+ previous versions it was based on. These may be placed in
+ the "History" section. You may omit a network location for a
+ work that was published at least four years before the
+ Document itself, or if the original publisher of the version
+ it refers to gives permission.
+
+ K. For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the
+ section all the substance and tone of each of the contributor
+ acknowledgements and/or dedications given therein.
+
+ L. Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section
+ titles.
+
+ M. Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+
+ N. Do not retitle any existing section to be Entitled
+ "Endorsements" or to conflict in title with any Invariant
+ Section.
+
+ O. Preserve any Warranty Disclaimers.
+
+ If the Modified Version includes new front-matter sections or
+ appendices that qualify as Secondary Sections and contain no
+ material copied from the Document, you may at your option
+ designate some or all of these sections as invariant. To do this,
+ add their titles to the list of Invariant Sections in the Modified
+ Version's license notice. These titles must be distinct from any
+ other section titles.
+
+ You may add a section Entitled "Endorsements", provided it contains
+ nothing but endorsements of your Modified Version by various
+ parties--for example, statements of peer review or that the text
+ has been approved by an organization as the authoritative
+ definition of a standard.
+
+ You may add a passage of up to five words as a Front-Cover Text,
+ and a passage of up to 25 words as a Back-Cover Text, to the end
+ of the list of Cover Texts in the Modified Version. Only one
+ passage of Front-Cover Text and one of Back-Cover Text may be
+ added by (or through arrangements made by) any one entity. If the
+ Document already includes a cover text for the same cover,
+ previously added by you or by arrangement made by the same entity
+ you are acting on behalf of, you may not add another; but you may
+ replace the old one, on explicit permission from the previous
+ publisher that added the old one.
+
+ The author(s) and publisher(s) of the Document do not by this
+ License give permission to use their names for publicity for or to
+ assert or imply endorsement of any Modified Version.
+
+ 5. COMBINING DOCUMENTS
+
+ You may combine the Document with other documents released under
+ this License, under the terms defined in section 4 above for
+ modified versions, provided that you include in the combination
+ all of the Invariant Sections of all of the original documents,
+ unmodified, and list them all as Invariant Sections of your
+ combined work in its license notice, and that you preserve all
+ their Warranty Disclaimers.
+
+ The combined work need only contain one copy of this License, and
+ multiple identical Invariant Sections may be replaced with a single
+ copy. If there are multiple Invariant Sections with the same name
+ but different contents, make the title of each such section unique
+ by adding at the end of it, in parentheses, the name of the
+ original author or publisher of that section if known, or else a
+ unique number. Make the same adjustment to the section titles in
+ the list of Invariant Sections in the license notice of the
+ combined work.
+
+ In the combination, you must combine any sections Entitled
+ "History" in the various original documents, forming one section
+ Entitled "History"; likewise combine any sections Entitled
+ "Acknowledgements", and any sections Entitled "Dedications". You
+ must delete all sections Entitled "Endorsements."
+
+ 6. COLLECTIONS OF DOCUMENTS
+
+ You may make a collection consisting of the Document and other
+ documents released under this License, and replace the individual
+ copies of this License in the various documents with a single copy
+ that is included in the collection, provided that you follow the
+ rules of this License for verbatim copying of each of the
+ documents in all other respects.
+
+ You may extract a single document from such a collection, and
+ distribute it individually under this License, provided you insert
+ a copy of this License into the extracted document, and follow
+ this License in all other respects regarding verbatim copying of
+ that document.
+
+ 7. AGGREGATION WITH INDEPENDENT WORKS
+
+ A compilation of the Document or its derivatives with other
+ separate and independent documents or works, in or on a volume of
+ a storage or distribution medium, is called an "aggregate" if the
+ copyright resulting from the compilation is not used to limit the
+ legal rights of the compilation's users beyond what the individual
+ works permit. When the Document is included in an aggregate, this
+ License does not apply to the other works in the aggregate which
+ are not themselves derivative works of the Document.
+
+ If the Cover Text requirement of section 3 is applicable to these
+ copies of the Document, then if the Document is less than one half
+ of the entire aggregate, the Document's Cover Texts may be placed
+ on covers that bracket the Document within the aggregate, or the
+ electronic equivalent of covers if the Document is in electronic
+ form. Otherwise they must appear on printed covers that bracket
+ the whole aggregate.
+
+ 8. TRANSLATION
+
+ Translation is considered a kind of modification, so you may
+ distribute translations of the Document under the terms of section
+ 4. Replacing Invariant Sections with translations requires special
+ permission from their copyright holders, but you may include
+ translations of some or all Invariant Sections in addition to the
+ original versions of these Invariant Sections. You may include a
+ translation of this License, and all the license notices in the
+ Document, and any Warranty Disclaimers, provided that you also
+ include the original English version of this License and the
+ original versions of those notices and disclaimers. In case of a
+ disagreement between the translation and the original version of
+ this License or a notice or disclaimer, the original version will
+ prevail.
+
+ If a section in the Document is Entitled "Acknowledgements",
+ "Dedications", or "History", the requirement (section 4) to
+ Preserve its Title (section 1) will typically require changing the
+ actual title.
+
+ 9. TERMINATION
+
+ You may not copy, modify, sublicense, or distribute the Document
+ except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense, or distribute it is void,
+ and will automatically terminate your rights under this License.
+
+ However, if you cease all violation of this License, then your
+ license from a particular copyright holder is reinstated (a)
+ provisionally, unless and until the copyright holder explicitly
+ and finally terminates your license, and (b) permanently, if the
+ copyright holder fails to notify you of the violation by some
+ reasonable means prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from
+ that copyright holder, and you cure the violation prior to 30 days
+ after your receipt of the notice.
+
+ Termination of your rights under this section does not terminate
+ the licenses of parties who have received copies or rights from
+ you under this License. If your rights have been terminated and
+ not permanently reinstated, receipt of a copy of some or all of
+ the same material does not give you any rights to use it.
+
+ 10. FUTURE REVISIONS OF THIS LICENSE
+
+ The Free Software Foundation may publish new, revised versions of
+ the GNU Free Documentation License from time to time. Such new
+ versions will be similar in spirit to the present version, but may
+ differ in detail to address new problems or concerns. See
+ `http://www.gnu.org/copyleft/'.
+
+ Each version of the License is given a distinguishing version
+ number. If the Document specifies that a particular numbered
+ version of this License "or any later version" applies to it, you
+ have the option of following the terms and conditions either of
+ that specified version or of any later version that has been
+ published (not as a draft) by the Free Software Foundation. If
+ the Document does not specify a version number of this License,
+ you may choose any version ever published (not as a draft) by the
+ Free Software Foundation. If the Document specifies that a proxy
+ can decide which future versions of this License can be used, that
+ proxy's public statement of acceptance of a version permanently
+ authorizes you to choose that version for the Document.
+
+ 11. RELICENSING
+
+ "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+ World Wide Web server that publishes copyrightable works and also
+ provides prominent facilities for anybody to edit those works. A
+ public wiki that anybody can edit is an example of such a server.
+ A "Massive Multiauthor Collaboration" (or "MMC") contained in the
+ site means any set of copyrightable works thus published on the MMC
+ site.
+
+ "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+ license published by Creative Commons Corporation, a not-for-profit
+ corporation with a principal place of business in San Francisco,
+ California, as well as future copyleft versions of that license
+ published by that same organization.
+
+ "Incorporate" means to publish or republish a Document, in whole or
+ in part, as part of another Document.
+
+ An MMC is "eligible for relicensing" if it is licensed under this
+ License, and if all works that were first published under this
+ License somewhere other than this MMC, and subsequently
+ incorporated in whole or in part into the MMC, (1) had no cover
+ texts or invariant sections, and (2) were thus incorporated prior
+ to November 1, 2008.
+
+ The operator of an MMC Site may republish an MMC contained in the
+ site under CC-BY-SA on the same site at any time before August 1,
+ 2009, provided the MMC is eligible for relicensing.
+
+
+ADDENDUM: How to use this License for your documents
+====================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+ Copyright (C) YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.3
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+ Texts. A copy of the license is included in the section entitled ``GNU
+ Free Documentation License''.
+
+ If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the "with...Texts." line with this:
+
+ with the Invariant Sections being LIST THEIR TITLES, with
+ the Front-Cover Texts being LIST, and with the Back-Cover Texts
+ being LIST.
+
+ If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+ If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License, to
+permit their use in free software.

+@chapter Introduction
+
+
+@noindent
+All symbols defined in the public API start with @code{MHD_}. MHD
+is a small HTTP daemon library. As such, it does not have any API
+for logging errors (you can only enable or disable logging to stderr).
+Also, it may not support all of the HTTP features directly, where
+applicable, portions of HTTP may have to be handled by clients of the
+library.
+
+The library is supposed to handle everything that it must handle
+(because the API would not allow clients to do this), such as basic
+connection management; however, detailed interpretations of headers ---
+such as range requests --- and HTTP methods are left to clients. The
+library does understand @code{HEAD} and will only send the headers of
+the response and not the body, even if the client supplied a body. The
+library also understands headers that control connection management
+(specifically, @code{Connection: close} and @code{Expect: 100 continue}
+are understood and handled automatically).
+
+MHD understands @code{POST} data and is able to decode certain
+formats (at the moment only @code{application/x-www-form-urlencoded}
+and @code{multipart/form-data}) using the post processor API. The
+data stream of a POST is also provided directly to the main
+application, so unsupported encodings could still be processed, just
+not conveniently by MHD.
+
+The header file defines various constants used by the HTTP protocol.
+This does not mean that MHD actually interprets all of these values.
+The provided constants are exported as a convenience for users of the
+library. MHD does not verify that transmitted HTTP headers are
+part of the standard specification; users of the library are free to
+define their own extensions of the HTTP standard and use those with
+MHD.
+
+All functions are guaranteed to be completely reentrant and
+thread-safe. MHD checks for allocation failures and tries to
+recover gracefully (for example, by closing the connection).
+Additionally, clients can specify resource limits on the overall
+number of connections, number of connections per IP address and memory
+used per connection to avoid resource exhaustion.
+
+@section Scope
+
+MHD is currently used in a wide range of implementations.
+Examples based on reports we've received from developers include:
+@itemize
+@item Embedded HTTP server on a cortex M3 (128 KB code space)
+@item Large-scale multimedia server (reportedly serving at the
+ simulator limit of 7.5 GB/s)
+@item Administrative console (via HTTP/HTTPS) for network appliances
+@c If you have other interesting examples, please let us know
+@end itemize
+
+@section Thread modes and event loops
+@cindex poll
+@cindex epoll
+@cindex select
+
+MHD supports four basic thread modes and up to three event loop
+styes.
+
+The four basic thread modes are external (MHD creates no threads,
+event loop is fully managed by the application), internal (MHD creates
+one thread for all connections), thread pool (MHD creates a thread
+pool which is used to process all connections) and
+thread-per-connection (MHD creates one listen thread and then one
+thread per accepted connection).
+
+These thread modes are then combined with the event loop styles.
+MHD support select, poll and epoll. epoll is only available on
+Linux, poll may not be available on some platforms. Note that
+it is possible to combine MHD using epoll with an external
+select-based event loop.
+
+The default (if no other option is passed) is ``external select''.
+The highest performance can typically be obtained with a thread pool
+using @code{epoll}. Apache Benchmark (ab) was used to compare the
+performance of @code{select} and @code{epoll} when using a thread pool
+and a large number of connections. @ref{fig:performance} shows the
+resulting plot from the @code{benchmark.c} example, which measures the
+latency between an incoming request and the completion of the
+transmission of the response. In this setting, the @code{epoll}
+thread pool with four threads was able to handle more than 45,000
+connections per second on loopback (with Apache Benchmark running
+three processes on the same machine).
+@cindex performance
+
+
+@float Figure,fig:performance
+@image{performance_data,400pt,300pt,Data,.png}
+@caption{Performance measurements for select vs. epoll (with thread-pool).}
+@end float
+
+
+Not all combinations of thread modes and event loop styles are
+supported. This is partially to keep the API simple, and partially
+because some combinations simply make no sense as others are strictly
+superior. Note that the choice of style depends fist of all on the
+application logic, and then on the performance requirements.
+Applications that perform a blocking operation while handling a
+request within the callbacks from MHD must use a thread per
+connection. This is typically rather costly. Applications that do
+not support threads or that must run on embedded devices without
+thread-support must use the external mode. Using @code{epoll} is only
+supported on Linux, thus portable applications must at least have a
+fallback option available. @ref{tbl:supported} lists the sane
+combinations.

+
+
+@section Compiling GNU libmicrohttpd
+@cindex compilation
+@cindex embedded systems
+@cindex portability
+
+MHD uses the standard GNU system where the usual build process
+involves running
+@verbatim
+$ ./configure
+$ make
+$ make install
+@end verbatim
+
+MHD supports various options to be given to configure to tailor the
+binary to a specific situation. Note that some of these options will
+remove portions of the MHD code that are required for
+binary-compatibility. They should only be used on embedded systems
+with tight resource constraints and no concerns about library
+versioning. Standard distributions including MHD are expected to
+always ship with all features enabled, otherwise unexpected
+incompatibilities can arise!
+
+Here is a list of MHD-specific options that can be given to configure
+(canonical configure options such as ``--prefix'' are also supported, for a
+full list of options run ``./configure --help''):
+
+@table @code
+@item ``--disable-curl''
+disable running testcases using libcurl
+
+@item ``--disable-largefile''
+disable support for 64-bit files
+
+@item ``--disable-messages''
+disable logging of error messages (smaller binary size, not so much fun for debugging)
+
+@item ``--disable-https''
+disable HTTPS support, even if GNUtls is found; this option must be used if eCOS license is desired as an option (in all cases the resulting binary falls under a GNU LGPL-only license)
+
+@item ``--disable-postprocessor''
+do not include the post processor API (results in binary incompatibility)
+
+@item ``--disable-dauth''
+do not include the authentication APIs (results in binary incompatibility)
+
+@item ``--disable-epoll
+do not include epoll support, even on Linux (minimally smaller binary size, good for testing portability to non-Linux systems)
+
+@item ``--enable-coverage''
+set flags for analysis of code-coverage with gcc/gcov (results in slow, large binaries)
+
+@item ``--with-gcrypt=PATH''
+specifies path to libgcrypt installation
+
+@item ``--with-gnutls=PATH''
+specifies path to libgnutls installation
+
+
+@end table
+
+@section Validity of pointers
+
+MHD will give applications access to its internal data structures
+via pointers via arguments and return values from its API. This
+creates the question as to how long those pointers are assured to
+stay valid.
+
+Most MHD data structures are associated with the connection of an
+HTTP client. Thus, pointers associated with a connection are
+typically valid until the connection is finished, at which point
+MHD will call the @code{MHD_RequestCompletedCallback} if one is
+registered. Applications that have such a callback registered
+may assume that keys and values from the
+@code{MHD_KeyValueIterator}, return values from
+@code{MHD_lookup_connection_value} and the @code{url},
+@code{method} and @code{version} arguments to the
+@code{MHD_AccessHandlerCallback} will remain valid until the
+respective @code{MHD_RequestCompletedCallback} is invoked.
+
+In contrast, the @code{upload_data} argument of
+@code{MHD_RequestCompletedCallback} as well as all pointers
+from the @code{MHD_PostDataIterator} are only valid for the
+duration of the callback.
+
+Pointers returned from @code{MHD_get_response_header} are
+valid as long as the response itself is valid.
+
+
+@section Including the microhttpd.h header
+@cindex portability
+@cindex microhttpd.h
+
+Ideally, before including "microhttpd.h" you should add the necessary
+includes to define the @code{uint64_t}, @code{size_t}, @code{fd_set},
+@code{socklen_t} and @code{struct sockaddr} data types. Which
+specific headers are needed may depend on your platform and your build
+system might include some tests to provide you with the necessary
+conditional operations. For possible suggestions consult
+@code{platform.h} and @code{configure.ac} in the MHD distribution.
+
+Once you have ensured that you manually (!) included the right headers
+for your platform before "microhttpd.h", you should also add a line
+with @code{#define MHD_PLATFORM_H} which will prevent the
+"microhttpd.h" header from trying (and, depending on your platform,
+failing) to include the right headers.
+
+If you do not define MHD_PLATFORM_H, the "microhttpd.h" header will
+automatically include headers needed on GNU/Linux systems (possibly
+causing problems when porting to other platforms).
+
+@section SIGPIPE
+@cindex signals
+MHD does not install a signal handler for SIGPIPE. On platforms
+where this is possible (such as GNU/Linux), it disables SIGPIPE for
+its I/O operations (by passing MSG_NOSIGNAL). On other platforms,
+SIGPIPE signals may be generated from network operations by
+MHD and will cause the process to die unless the developer
+explicitly installs a signal handler for SIGPIPE.
+
+Hence portable code using MHD must install a SIGPIPE handler or
+explicitly block the SIGPIPE signal. MHD does not do so in order
+to avoid messing with other parts of the application that may
+need to handle SIGPIPE in a particular way. You can make your application handle SIGPIPE by calling the following function in @code{main}:
+
+@verbatim
+static void
+catcher (int sig)
+{
+}
+
+static void
+ignore_sigpipe ()
+{
+ struct sigaction oldsig;
+ struct sigaction sig;
+
+ sig.sa_handler = &catcher;
+ sigemptyset (&sig.sa_mask);
+#ifdef SA_INTERRUPT
+ sig.sa_flags = SA_INTERRUPT; /* SunOS */
+#else
+ sig.sa_flags = SA_RESTART;
+#endif

+@cindex cortex m3
+@cindex embedded systems
+
+Some platforms do not support @code{long long}. Hence MHD defines a
+macro @code{MHD_UNSIGNED LONG_LONG} which will default to
+@code{unsigned long long}. For standard desktop operating systems,
+this is all you need to know.
+
+However, if your platform does not support @code{unsigned long long},
+you should change "platform.h" to define @code{MHD_LONG_LONG} and
+@code{MHD_UNSIGNED_LONG_LONG} to an appropriate alternative type and
+also define @code{MHD_LONG_LONG_PRINTF} and
+@code{MHD_UNSIGNED_LONG_LONG_PRINTF} to the corresponding format
+string for printing such a data type. Note that the ``signed''
+versions are deprecated. Also, for historical reasons,
+@code{MHD_LONG_LONG_PRINTF} is without the percent sign, whereas
+@code{MHD_UNSIGNED_LONG_LONG_PRINTF} is with the percent sign. Newly
+written code should only use the unsigned versions. However, you need
+to define both in "platform.h" if you need to change the definition
+for the specific platform.
+
+
+@section Portability to W32
+
+libmicrohttpd in general ported well to W32. Most libmicrohttpd features
+are supported. W32 do not support some functions, like epoll and
+corresponding MHD features are not available on W32.
+
+
+@section Portability to z/OS
+
+To compile MHD on z/OS, extract the archive and run
+
+@verbatim
+iconv -f UTF-8 -t IBM-1047 contrib/ascebc > /tmp/ascebc.sh
+chmod +x /tmp/ascebc.sh
+for n in `find * -type f`
+do
+ /tmp/ascebc.sh $n
+done
+@end verbatim
+to convert all source files to EBCDIC. Note that you must run
+@code{configure} from the directory where the configure script is
+located. Otherwise, configure will fail to find the
+@code{contrib/xcc} script (which is a wrapper around the z/OS c89
+compiler).

+
+@deftp {Enumeration} MHD_FLAG
+Options for the MHD daemon.
+
+Note that if neither @code{MHD_USE_THREAD_PER_CONNECTION} nor
+@code{MHD_USE_SELECT_INTERNALLY} is used, the client wants control over
+the process and will call the appropriate microhttpd callbacks.
+
+Starting the daemon may also fail if a particular option is not
+implemented or not supported on the target platform (i.e. no support for
+@acronym{SSL}, threads or IPv6). SSL support generally depends on
+options given during MHD compilation. Threaded operations
+(including @code{MHD_USE_SELECT_INTERNALLY}) are not supported on
+Symbian.
+
+@table @code
+@item MHD_NO_FLAG
+No options selected.
+
+@item MHD_USE_DEBUG
+@cindex debugging
+Run in debug mode. If this flag is used, the library should print error
+messages and warnings to stderr. Note that for this
+run-time option to have any effect, MHD needs to be
+compiled with messages enabled. This is done by default except you ran
+configure with the @code{--disable-messages} flag set.
+
+@item MHD_USE_SSL
+@cindex TLS
+@cindex SSL
+Run in HTTPS-mode. If you specify @code{MHD_USE_SSL} and MHD was
+compiled without SSL support, @code{MHD_start_daemon} will return
+NULL.
+
+@item MHD_USE_THREAD_PER_CONNECTION
+Run using one thread per connection.
+
+@item MHD_USE_SELECT_INTERNALLY
+Run using an internal thread doing @code{SELECT}.
+
+@item MHD_USE_IPv6
+@cindex IPv6
+Run using the IPv6 protocol (otherwise, MHD will just support IPv4).
+If you specify @code{MHD_USE_IPV6} and the local platform does not
+support it, @code{MHD_start_daemon} will return NULL.
+
+If you want MHD to support IPv4 and IPv6 using a single socket, pass
+MHD_USE_DUAL_STACK, otherwise, if you only pass this option, MHD will
+try to bind to IPv6-only (resulting in no IPv4 support).
+
+@item MHD_USE_DUAL_STACK
+@cindex IPv6
+Use a single socket for IPv4 and IPv6. Note that this will mean
+that IPv4 addresses are returned by MHD in the IPv6-mapped format
+(the 'struct sockaddr_in6' format will be used for IPv4 and IPv6).
+
+@item MHD_USE_PEDANTIC_CHECKS
+Be pedantic about the protocol (as opposed to as tolerant as possible).
+Specifically, at the moment, this flag causes MHD to reject HTTP
+1.1 connections without a @code{Host} header. This is required by the
+standard, but of course in violation of the ``be as liberal as possible
+in what you accept'' norm. It is recommended to turn this @strong{ON}
+if you are testing clients against MHD, and @strong{OFF} in
+production.
+
+@item MHD_USE_POLL
+@cindex FD_SETSIZE
+@cindex poll
+@cindex select
+Use poll instead of select. This allows sockets with descriptors
+@code{>= FD_SETSIZE}. This option currently only works in conjunction
+with @code{MHD_USE_THREAD_PER_CONNECTION} or
+@code{MHD_USE_INTERNAL_SELECT} (at this point). If you specify
+@code{MHD_USE_POLL} and the local platform does not support it,
+@code{MHD_start_daemon} will return NULL.
+
+@item MHD_USE_EPOLL_LINUX_ONLY
+@cindex FD_SETSIZE
+@cindex epoll
+@cindex select
+Use epoll instead of poll or select. This allows sockets with
+descriptors @code{>= FD_SETSIZE}. This option is only available on
+Linux systems and only works in conjunction with
+@code{MHD_USE_THREAD_PER_CONNECTION} (at this point). If you specify
+@code{MHD_USE_EPOLL_LINUX_ONLY} and the local platform does not
+support it, @code{MHD_start_daemon} will return NULL. Using epoll
+instead of select or poll can in some situations result in significantly
+higher performance as the system call has fundamentally lower complexity
+(O(1) for epoll vs. O(n) for select/poll where n is the number of
+open connections).
+
+@item MHD_SUPPRESS_DATE_NO_CLOCK
+@cindex date
+@cindex clock
+@cindex embedded systems
+Suppress (automatically) adding the 'Date:' header to HTTP responses.
+This option should ONLY be used on systems that do not have a clock
+and that DO provide other mechanisms for cache control. See also
+RFC 2616, section 14.18 (exception 3).
+
+
+@item MHD_USE_NO_LISTEN_SOCKET
+@cindex listen
+@cindex proxy
+@cindex embedded systems
+Run the HTTP server without any listen socket. This option only makes
+sense if @code{MHD_add_connection} is going to be used exclusively to
+connect HTTP clients to the HTTP server. This option is incompatible
+with using a thread pool; if it is used,
+@code{MHD_OPTION_THREAD_POOL_SIZE} is ignored.
+
+@item MHD_USE_PIPE_FOR_SHUTDOWN
+@cindex quiesce
+Force MHD to use a signal pipe to notify the event loop (of threads)
+of our shutdown. This is required if an appliction uses
+@code{MHD_USE_INTERNAL_SELECT} or @code{MHD_USE_THREAD_PER_CONNECTION}
+and then performs @code{MHD_quiesce_daemon} (which eliminates our
+ability to signal termination via the listen socket). In these modes,
+@code{MHD_quiesce_daemon} will fail if this option was not set. Also,
+use of this option is automatic (as in, you do not even have to
+specify it), if @code{MHD_USE_NO_LISTEN_SOCKET} is specified. In
+"external" select mode, this option is always simply ignored.
+
+@item MHD_USE_SUSPEND_RESUME
+Enables using @code{MHD_suspend_connection} and
+@code{MHD_resume_connection}, as performing these calls requires some
+additional pipes to be created, and code not using these calls should
+not pay the cost.
+
+@item MHD_USE_TCP_FASTOPEN
+@cindex listen
+Enable TCP_FASTOPEN on the listen socket. TCP_FASTOPEN is currently
+supported on Linux >= 3.6. On other systems using this option with
+cause @code{MHD_start_daemon} to fail.
+
+@end table
+@end deftp
+
+
+@deftp {Enumeration} MHD_OPTION
+MHD options. Passed in the varargs portion of
+@code{MHD_start_daemon()}.
+
+@table @code
+@item MHD_OPTION_END
+No more options / last option. This is used to terminate the VARARGs
+list.
+
+@item MHD_OPTION_CONNECTION_MEMORY_LIMIT
+@cindex memory, limiting memory utilization
+Maximum memory size per connection (followed by a @code{size_t}). The
+default is 32 kB (32*1024 bytes) as defined by the internal constant
+@code{MHD_POOL_SIZE_DEFAULT}. Values above 128k are unlikely to
+result in much benefit, as half of the memory will be typically used
+for IO, and TCP buffers are unlikely to support window sizes above 64k
+on most systems.
+
+@item MHD_OPTION_CONNECTION_MEMORY_INCREMENT
+@cindex memory
+Increment to use for growing the read buffer (followed by a
+@code{size_t}). The default is 1024 (bytes). Increasing this value
+will make MHD use memory for reading more aggressively, which can
+reduce the number of @code{recvfrom} calls but may increase the number
+of @code{sendto} calls. The given value must fit within
+MHD_OPTION_CONNECTION_MEMORY_LIMIT.
+
+@item MHD_OPTION_CONNECTION_LIMIT
+@cindex connection, limiting number of connections
+Maximum number of concurrent connections to accept (followed by an
+@code{unsigned int}). The default is @code{FD_SETSIZE - 4} (the
+maximum number of file descriptors supported by @code{select} minus
+four for @code{stdin}, @code{stdout}, @code{stderr} and the server
+socket). In other words, the default is as large as possible.
+
+Note that if you set a low connection limit, you can easily get into
+trouble with browsers doing request pipelining. For example, if your
+connection limit is ``1'', a browser may open a first connection to
+access your ``index.html'' file, keep it open but use a second
+connection to retrieve CSS files, images and the like. In fact, modern
+browsers are typically by default configured for up to 15 parallel
+connections to a single server. If this happens, MHD will refuse to
+even accept the second connection until the first connection is
+closed --- which does not happen until timeout. As a result, the
+browser will fail to render the page and seem to hang. If you expect
+your server to operate close to the connection limit, you should
+first consider using a lower timeout value and also possibly add
+a ``Connection: close'' header to your response to ensure that
+request pipelining is not used and connections are closed immediately
+after the request has completed:
+@example
+MHD_add_response_header (response,
+ MHD_HTTP_HEADER_CONNECTION,
+ "close");
+@end example
+
+@item MHD_OPTION_CONNECTION_TIMEOUT
+@cindex timeout
+After how many seconds of inactivity should a connection automatically
+be timed out? (followed by an @code{unsigned int}; use zero for no
+timeout). The default is zero (no timeout).
+
+@item MHD_OPTION_NOTIFY_COMPLETED
+Register a function that should be called whenever a request has been
+completed (this can be used for application-specific clean up).
+Requests that have never been presented to the application (via
+@code{MHD_AccessHandlerCallback()}) will not result in
+notifications.
+
+This option should be followed by @strong{TWO} pointers. First a
+pointer to a function of type @code{MHD_RequestCompletedCallback()}
+and second a pointer to a closure to pass to the request completed
+callback. The second pointer maybe @code{NULL}.
+
+@item MHD_OPTION_NOTIFY_CONNECTION
+Register a function that should be called when the TCP connection to a
+client is opened or closed. Note that
+@code{MHD_OPTION_NOTIFY_COMPLETED} and the @code{con_cls} argument to
+the @code{MHD_AccessHandlerCallback} are per HTTP request (and there
+can be multiple HTTP requests per TCP connection). The registered
+callback is called twice per TCP connection, with
+@code{MHD_CONNECTION_NOTIFY_STARTED} and
+@code{MHD_CONNECTION_NOTIFY_CLOSED} respectively. An additional
+argument can be used to store TCP connection specific information,
+which can be retrieved using @code{MHD_CONNECTION_INFO_SOCKET_CONTEXT}
+during the lifetime of the TCP connection. The respective location is
+not the same as the HTTP-request-specific @code{con_cls} from the
+@code{MHD_AccessHandlerCallback}.
+
+This option should be followed by @strong{TWO} pointers. First a
+pointer to a function of type @code{MHD_NotifyConnectionCallback()}
+and second a pointer to a closure to pass to the request completed
+callback. The second pointer maybe @code{NULL}.
+
+@item MHD_OPTION_PER_IP_CONNECTION_LIMIT
+Limit on the number of (concurrent) connections made to the
+server from the same IP address. Can be used to prevent one
+IP from taking over all of the allowed connections. If the
+same IP tries to establish more than the specified number of
+connections, they will be immediately rejected. The option
+should be followed by an @code{unsigned int}. The default is
+zero, which means no limit on the number of connections
+from the same IP address.
+
+@item MHD_OPTION_SOCK_ADDR
+@cindex bind, restricting bind
+Bind daemon to the supplied socket address. This option should be followed by a
+@code{struct sockaddr *}. If @code{MHD_USE_IPv6} is specified,
+the @code{struct sockaddr*} should point to a @code{struct sockaddr_in6},
+otherwise to a @code{struct sockaddr_in}. If this option is not specified,
+the daemon will listen to incoming connections from anywhere. If you use this
+option, the 'port' argument from @code{MHD_start_daemon} is ignored and the port
+from the given @code{struct sockaddr *} will be used instead.
+
+@item MHD_OPTION_URI_LOG_CALLBACK
+@cindex debugging
+@cindex logging
+@cindex query string
+Specify a function that should be called before parsing the URI from
+the client. The specified callback function can be used for processing
+the URI (including the options) before it is parsed. The URI after
+parsing will no longer contain the options, which maybe inconvenient for
+logging. This option should be followed by two arguments, the first
+one must be of the form
+@example
+ void * my_logger(void * cls, const char * uri, struct MHD_Connection *con)
+@end example
+where the return value will be passed as
+@code{*con_cls} in calls to the @code{MHD_AccessHandlerCallback}
+when this request is processed later; returning a
+value of @code{NULL} has no special significance; (however,
+note that if you return non-@code{NULL}, you can no longer
+rely on the first call to the access handler having
+@code{NULL == *con_cls} on entry)
+@code{cls} will be set to the second argument following
+MHD_OPTION_URI_LOG_CALLBACK. Finally, @code{uri} will
+be the 0-terminated URI of the request.
+
+Note that during the time of this call, most of the connection's state
+is not initialized (as we have not yet parsed he headers). However,
+information about the connecting client (IP, socket) is available.
+
+@item MHD_OPTION_HTTPS_MEM_KEY
+@cindex SSL
+@cindex TLS
+Memory pointer to the private key to be used by the
+HTTPS daemon. This option should be followed by an
+"const char*" argument.
+This should be used in conjunction with 'MHD_OPTION_HTTPS_MEM_CERT'.
+
+@item MHD_OPTION_HTTPS_KEY_PASSWORD
+@cindex SSL
+@cindex TLS
+Memory pointer to the password that decrypts the
+private key to be used by the HTTPS daemon.
+This option should be followed by an
+"const char*" argument.
+This should be used in conjunction with 'MHD_OPTION_HTTPS_MEM_KEY'.
+
+The password (or passphrase) is only used immediately during
+@code{MHD_start_daemon()}. Thus, the application may want to
+erase it from memory afterwards for additional security.
+
+@item MHD_OPTION_HTTPS_MEM_CERT
+@cindex SSL
+@cindex TLS
+Memory pointer to the certificate to be used by the
+HTTPS daemon. This option should be followed by an
+"const char*" argument.
+This should be used in conjunction with 'MHD_OPTION_HTTPS_MEM_KEY'.
+
+@item MHD_OPTION_HTTPS_MEM_TRUST
+@cindex SSL
+@cindex TLS
+Memory pointer to the CA certificate to be used by the
+HTTPS daemon to authenticate and trust clients certificates.
+This option should be followed by an "const char*" argument.
+The presence of this option activates the request of certificate
+to the client. The request to the client is marked optional, and
+it is the responsibility of the server to check the presence
+of the certificate if needed.
+Note that most browsers will only present a client certificate
+only if they have one matching the specified CA, not sending
+any certificate otherwise.
+
+@item MHD_OPTION_HTTPS_CRED_TYPE
+@cindex SSL
+@cindex TLS
+Daemon credentials type. Either certificate or anonymous,
+this option should be followed by one of the values listed in
+"enum gnutls_credentials_type_t".
+
+@item MHD_OPTION_HTTPS_PRIORITIES
+@cindex SSL
+@cindex TLS
+@cindex cipher
+SSL/TLS protocol version and ciphers.
+This option must be followed by an "const char *" argument
+specifying the SSL/TLS protocol versions and ciphers that
+are acceptable for the application. The string is passed
+unchanged to gnutls_priority_init. If this option is not
+specified, ``NORMAL'' is used.
+
+@item MHD_OPTION_HTTPS_CERT_CALLBACK
+@cindex SSL
+@cindex TLS
+@cindex SNI
+Use a callback to determine which X.509 certificate should be used for
+a given HTTPS connection. This option should be followed by a
+argument of type "gnutls_certificate_retrieve_function2 *". This
+option provides an alternative to MHD_OPTION_HTTPS_MEM_KEY and
+MHD_OPTION_HTTPS_MEM_CERT. You must use this version if multiple
+domains are to be hosted at the same IP address using TLS's Server
+Name Indication (SNI) extension. In this case, the callback is
+expected to select the correct certificate based on the SNI
+information provided. The callback is expected to access the SNI data
+using gnutls_server_name_get(). Using this option requires GnuTLS 3.0
+or higher.
+
+@item MHD_OPTION_DIGEST_AUTH_RANDOM
+@cindex digest auth
+@cindex random
+Digest Authentication nonce's seed.
+
+This option should be followed by two arguments. First an integer of
+type "size_t" which specifies the size of the buffer pointed to by the
+second argument in bytes. Note that the application must ensure that
+the buffer of the second argument remains allocated and unmodified
+while the daemon is running. For security, you SHOULD provide a fresh
+random nonce when using MHD with Digest Authentication.
+
+@item MHD_OPTION_NONCE_NC_SIZE
+@cindex digest auth
+@cindex replay attack
+
+Size of an array of nonce and nonce counter map. This option must be
+followed by an "unsigned int" argument that have the size (number of
+elements) of a map of a nonce and a nonce-counter. If this option
+is not specified, a default value of 4 will be used (which might be
+too small for servers handling many requests). If you do not use
+digest authentication at all, you can specify a value of zero to
+save some memory.
+
+You should calculate the value of NC_SIZE based on the number of
+connections per second multiplied by your expected session duration
+plus a factor of about two for hash table collisions. For example, if
+you expect 100 digest-authenticated connections per second and the
+average user to stay on your site for 5 minutes, then you likely need
+a value of about 60000. On the other hand, if you can only expect
+only 10 digest-authenticated connections per second, tolerate browsers
+getting a fresh nonce for each request and expect a HTTP request
+latency of 250 ms, then a value of about 5 should be fine.
+
+
+@item MHD_OPTION_LISTEN_SOCKET
+@cindex systemd
+Listen socket to use. Pass a listen socket for MHD to use
+(systemd-style). If this option is used, MHD will not open its own
+listen socket(s). The argument passed must be of type "int" and refer
+to an existing socket that has been bound to a port and is listening.
+
+@item MHD_OPTION_EXTERNAL_LOGGER
+@cindex logging
+Use the given function for logging error messages.
+This option must be followed by two arguments; the
+first must be a pointer to a function
+of type 'void fun(void * arg, const char * fmt, va_list ap)'
+and the second a pointer of type 'void*' which will
+be passed as the "arg" argument to "fun".
+
+Note that MHD will not generate any log messages without
+the MHD_USE_DEBUG flag set and if MHD was compiled
+with the "--disable-messages" flag.
+
+@item MHD_OPTION_THREAD_POOL_SIZE
+@cindex performance
+Number (unsigned int) of threads in thread pool. Enable
+thread pooling by setting this value to to something
+greater than 1. Currently, thread model must be
+MHD_USE_SELECT_INTERNALLY if thread pooling is enabled
+(@code{MHD_start_daemon} returns @code{NULL} for an unsupported thread
+model).
+
+@item MHD_OPTION_ARRAY
+@cindex options
+@cindex foreign-function interface
+This option can be used for initializing MHD using options from an
+array. A common use for this is writing an FFI for MHD. The actual
+options given are in an array of 'struct MHD_OptionItem', so this
+option requires a single argument of type 'struct MHD_OptionItem'.
+The array must be terminated with an entry @code{MHD_OPTION_END}.
+
+An example for code using MHD_OPTION_ARRAY is:
+@example
+struct MHD_OptionItem ops[] = @{
+ @{ MHD_OPTION_CONNECTION_LIMIT, 100, NULL @},
+ @{ MHD_OPTION_CONNECTION_TIMEOUT, 10, NULL @},
+ @{ MHD_OPTION_END, 0, NULL @}
+@};
+d = MHD_start_daemon(0, 8080, NULL, NULL, dh, NULL,
+ MHD_OPTION_ARRAY, ops,
+ MHD_OPTION_END);
+@end example
+For options that expect a single pointer argument, the
+second member of the @code{struct MHD_OptionItem} is ignored.
+For options that expect two pointer arguments, the first
+argument must be cast to @code{intptr_t}.
+
+@item MHD_OPTION_UNESCAPE_CALLBACK
+@cindex internationalization
+@cindex escaping
+
+Specify a function that should be called for unescaping escape
+sequences in URIs and URI arguments. Note that this function will NOT
+be used by the MHD_PostProcessor. If this option is not specified,
+the default method will be used which decodes escape sequences of the
+form "%HH". This option should be followed by two arguments, the
+first one must be of the form
+
+@example
+ size_t my_unescaper(void * cls, struct MHD_Connection *c, char *s)
+@end example
+
+where the return value must be @code{strlen(s)} and @code{s} should be
+updated. Note that the unescape function must not lengthen @code{s}
+(the result must be shorter than the input and still be 0-terminated).
+@code{cls} will be set to the second argument following
+MHD_OPTION_UNESCAPE_CALLBACK.
+
+
+@item MHD_OPTION_THREAD_STACK_SIZE
+@cindex stack
+@cindex thread
+@cindex pthread
+@cindex embedded systems
+Maximum stack size for threads created by MHD. This option must be
+followed by a @code{size_t}). Not specifying this option or using
+a value of zero means using the system default (which is likely to
+differ based on your platform).
+
+@item MHD_OPTION_TCP_FASTQUEUE_QUEUE_SIZE
+@cindex listen
+When the flag @code{MHD_USE_TCP_FASTOPEN} is used, this option sets the
+connection handshake queue size for the TCP FASTOPEN connections. Note
+that a TCP FASTOPEN connection handshake occupies more resources than a
+TCP handshake as the SYN packets also contain DATA which is kept in the
+associate state until handshake is completed. If this option is not
+given the queue size is set to a default value of 10. This option must
+be followed by a @code{unsigned int}.
+
+@item MHD_OPTION_HTTPS_MEM_DHPARAMS
+@cindex TLS
+@cindex SSL
+@cindex DH
+Memory pointer for the Diffie-Hellman parameters (dh.pem) to be used
+by the HTTPS daemon for key exchange. This option must be followed by
+a @code{const char *} argument. The argument would be a zero-terminated
+string with a PEM encoded PKCS3 DH parameters structure suitable
+for passing to @code{gnutls_dh_parms_import_pkcs3}.
+
+@item MHD_OPTION_LISTENING_ADDRESS_REUSE
+@cindex bind, restricting bind
+@cindex reusing listening address
+This option must be followed by a @code{unsigned int} argument.
+If this option is present and true (nonzero) parameter is given, allow reusing
+the address:port of the listening socket (using @code{SO_REUSEPORT} on most
+platforms, and @code{SO_REUSEADDR} on Windows). If a false (zero) parameter is
+given, disallow reusing the the address:port of the listening socket (this
+usually requires no special action, but @code{SO_EXCLUSIVEADDRUSE} is needed on
+Windows). If this option is not present, default behaviour is undefined
+(currently, @code{SO_REUSEADDR} is used on all platforms, which disallows
+address:port reusing with the exception of Windows).
+
+@end table

+
+@deftp {C Struct} MHD_OptionItem
+Entry in an MHD_OPTION_ARRAY. See the @code{MHD_OPTION_ARRAY} option
+argument for its use.
+
+The @code{option} member is used to specify which option is specified
+in the array. The other members specify the respective argument.
+
+Note that for options taking only a single pointer, the
+@code{ptr_value} member should be set. For options taking two pointer
+arguments, the first pointer must be cast to @code{intptr_t} and both
+the @code{value} and the @code{ptr_value} members should be used to

+Invoked in the context of a connection to answer a request from the
+client. This callback must call MHD functions (example: the

+and return an HTTP status code (i.e. @code{200} for OK, @code{404},
+etc.).

+the data being uploaded (excluding headers):
+@cindex POST method
+@cindex PUT method
+
+@code{POST} data @strong{will} be made available
+incrementally in @var{upload_data}; even if @code{POST}
+data is available, the first time the callback is
+invoked there won't be upload data, as this is done
+just after MHD parses the headers. If supported by
+the client and the HTTP version, the application can
+at this point queue an error response to possibly
+avoid the upload entirely. If no response is generated,
+MHD will (if required) automatically send a 100 CONTINUE
+reply to the client.
+
+Afterwards, POST data will be passed to the callback
+to be processed incrementally by the application. The
+application may return @code{MHD_NO} to forcefully
+terminate the TCP connection without generating a
+proper HTTP response. Once all of the upload data has
+been provided to the application, the application
+will be called again with 0 bytes of upload data.
+At this point, a response should be queued to complete
+the handling of the request.
+
+@item upload_data_size
+set initially to the size of the @var{upload_data} provided; this
+callback must update this value to the number of bytes @strong{NOT}
+processed; unless external select is used, the callback maybe
+required to process at least some data. If the callback fails to
+process data in multi-threaded or internal-select mode and if the
+read-buffer is already at the maximum size that MHD is willing to
+use for reading (about half of the maximum amount of memory allowed
+for the connection), then MHD will abort handling the connection
+and return an internal server error to the client. In order to
+avoid this, clients must be able to process upload data incrementally
+and reduce the value of @code{upload_data_size}.
+
+@item con_cls
+reference to a pointer, initially set to @code{NULL}, that this callback can
+set to some address and that will be preserved by MHD for future
+calls for this request;
+
+since the access handler may be called many times (i.e., for a
+@code{PUT}/@code{POST} operation with plenty of upload data) this allows
+the application to easily associate some request-specific state;
+
+if necessary, this state can be cleaned up in the global
+@code{MHD_RequestCompletedCallback} (which can be set with the
+@code{MHD_OPTION_NOTIFY_COMPLETED}).

+Thus, returning zero should only be used in conjunction

+that while returning @code{MHD_CONTENT_READER_END_OF_STREAM} is not technically
+legal if a response size was specified, MHD accepts this
+and treats it just as @code{MHD_CONTENT_READER_END_WITH_ERROR}.
+
+@code{MHD_CONTENT_READER_END_WITH_ERROR} (-2) is used to indicate a server

+The @var{iterator} callback is invoked once for each header, with

+
+@var{connection} is the connection for which

+Response objects handling by MHD is asynchronous with respect to the

+structure are not associated to a daemon and neither to a client
+connection: they are managed with reference counting.
+
+In the simplest case: we allocate a new @code{MHD_Response} structure
+for each response, we use it once and finally we destroy it.
+
+MHD allows more efficient resources usages.
+
+Example: we allocate a new @code{MHD_Response} structure for each
+response @strong{kind}, we use it every time we have to give that
+response and we finally destroy it only when the daemon shuts down.

+Sometimes it may be possible that clients upload data faster

+needs an extended period of time to generate a response.
+If @code{MHD_USE_THREAD_PER_CONNECTION} is used, applications
+can simply deal with this by performing their logic within the
+thread and thus effectively blocking connection processing
+by MHD. In all other modes, blocking logic must not be
+placed within the callbacks invoked by MHD as this would also
+block processing of other requests, as a single thread may be
+responsible for tens of thousands of connections.
+
+Instead, applications using thread modes other than

+Suspend handling of network data for a given connection. This can

+
+If you use this API in conjunction with a internal select or a
+thread pool, you must set the option @code{MHD_USE_SUSPEND_RESUME} to
+ensure that a resumed connection is immediately processed by MHD.
+
+Suspended connections continue to count against the total number of
+connections allowed (per daemon, as well as per IP, if such limits
+are set). Suspended connections will NOT time out; timeouts will
+restart when the connection handling is resumed. While a
+connection is suspended, MHD will not detect disconnects by the
+client.
+
+The only safe time to suspend a connection is from the
+@code{MHD_AccessHandlerCallback}.
+
+Finally, it is an API violation to call @code{MHD_stop_daemon} while

+@node microhttpd-dauth
+@chapter Utilizing Authentication
+
+@noindent
+MHD support three types of client authentication.
+
+Basic authentication uses a simple authentication method based
+on BASE64 algorithm. Username and password are exchanged in clear
+between the client and the server, so this method must only be used
+for non-sensitive content or when the session is protected with https.
+When using basic authentication MHD will have access to the clear
+password, possibly allowing to create a chained authentication
+toward an external authentication server.
+
+Digest authentication uses a one-way authentication method based
+on MD5 hash algorithm. Only the hash will transit over the network,
+hence protecting the user password. The nonce will prevent replay
+attacks. This method is appropriate for general use, especially
+when https is not used to encrypt the session.
+
+Client certificate authentication uses a X.509 certificate from
+the client. This is the strongest authentication mechanism but it
+requires the use of HTTPS. Client certificate authentication can
+be used simultaneously with Basic or Digest Authentication in order
+to provide a two levels authentication (like for instance separate
+machine and user authentication). A code example for using
+client certificates is presented in the MHD tutorial.

+

+* microhttpd-post api:: Programming interface for the
+ @code{POST} processor.
+@end menu
+
+
+@noindent
+MHD provides the post processor API to make it easier for applications to
+parse the data of a client's @code{POST} request: the
+@code{MHD_AccessHandlerCallback} will be invoked multiple times to
+process data as it arrives; at each invocation a new chunk of data must
+be processed. The arguments @var{upload_data} and @var{upload_data_size}
+are used to reference the chunk of data.
+
+When @code{MHD_AccessHandlerCallback} is invoked for a new connection:
+its @code{*@var{con_cls}} argument is set to @code{NULL}. When @code{POST}
+data comes in the upload buffer it is @strong{mandatory} to use the
+@var{con_cls} to store a reference to per-connection data. The fact
+that the pointer was initially @code{NULL} can be used to detect that
+this is a new request.
+
+One method to detect that a new connection was established is
+to set @code{*con_cls} to an unused integer:
+
+@example
+int
+access_handler (void *cls,
+ struct MHD_Connection * connection,
+ const char *url,
+ const char *method, const char *version,
+ const char *upload_data, size_t *upload_data_size,
+ void **con_cls)
+@{
+ static int old_connection_marker;
+ int new_connection = (NULL == *con_cls);
+
+ if (new_connection)
+ @{
+ /* new connection with POST */
+ *con_cls = &old_connection_marker;
+ @}
+
+ ...
+@}
+@end example
+
+@noindent
+In contrast to the previous example, for @code{POST} requests in particular,
+it is more common to use the value of @code{*con_cls} to keep track of
+actual state used during processing, such as the post processor (or a
+struct containing a post processor):
+
+@example
+int
+access_handler (void *cls,
+ struct MHD_Connection * connection,
+ const char *url,
+ const char *method, const char *version,
+ const char *upload_data, size_t *upload_data_size,
+ void **con_cls)
+@{
+ struct MHD_PostProcessor * pp = *con_cls;
+
+ if (pp == NULL)
+ @{
+ pp = MHD_create_post_processor(connection, ...);
+ *con_cls = pp;
+ return MHD_YES;
+ @}
+ if (*upload_data_size)
+ @{
+ MHD_post_process(pp, upload_data, *upload_data_size);
+ *upload_data_size = 0;
+ return MHD_YES;
+ @}
+ else
+ @{
+ MHD_destroy_post_processor(pp);
+ return MHD_queue_response(...);
+ @}
+@}
+@end example
+
+Note that the callback from @code{MHD_OPTION_NOTIFY_COMPLETED}
+should be used to destroy the post processor. This cannot be
+done inside of the access handler since the connection may not
+always terminate normally.

+Obtain information about the given daemon. This function
+is currently not fully implemented.
+
+@table @var
+@item daemon
+the daemon about which information is desired;
+
+@item infoType
+type of information that is desired
+
+@item ...
+additional arguments about the desired information (depending on
+infoType)

+@end deftypefun
+
+
+@deftp {Enumeration} MHD_DaemonInfoType
+Values of this enum are used to specify what
+information about a daemon is desired.
+@table @code
+@item MHD_DAEMON_INFO_KEY_SIZE
+Request information about the key size for a particular cipher
+algorithm. The cipher algorithm should be passed as an extra argument
+(of type 'enum MHD_GNUTLS_CipherAlgorithm'). No longer supported,
+using this value will cause @code{MHD_get_daemon_info} to return NULL.
+
+@item MHD_DAEMON_INFO_MAC_KEY_SIZE
+Request information about the key size for a particular cipher
+algorithm. The cipher algorithm should be passed as an extra argument
+(of type 'enum MHD_GNUTLS_HashAlgorithm'). No longer supported,
+using this value will cause @code{MHD_get_daemon_info} to return NULL.
+
+@item MHD_DAEMON_INFO_LISTEN_FD
+@cindex listen
+Request the file-descriptor number that MHD is using to listen to the
+server socket. This can be useful if no port
+was specified and a client needs to learn what port
+is actually being used by MHD.
+No extra arguments should be passed.
+
+@item MHD_DAEMON_INFO_EPOLL_FD_LINUX_ONLY
+@cindex epoll
+Request the file-descriptor number that MHD is using for epoll. If
+the build is not supporting epoll, NULL is returned; if we are using a
+thread pool or this daemon was not started with
+@code{MHD_USE_EPOLL_LINUX_ONLY}, (a pointer to) -1 is returned. If we are
+using @code{MHD_USE_SELECT_INTERNALLY} or are in 'external' select mode, the
+internal epoll FD is returned. This function must be used in external
+select mode with epoll to obtain the FD to call epoll on. No extra
+arguments should be passed.
+
+@item MHD_DAEMON_INFO_CURRENT_CONNECTIONS
+@cindex connection, limiting number of connections
+Request the number of current connections handled by the daemon. No
+extra arguments should be passed and a pointer to a @code{union
+MHD_DaemonInfo} value is returned, with the @code{num_connections}
+member of type @code{unsigned int} set to the number of active
+connections.
+
+Note that in multi-threaded or internal-select mode, the real number of current
+connections may already be different when @code{MHD_get_daemon_info} returns.
+The number of current connections can be used (even in multi-threaded and
+internal-select mode) after @code{MHD_quiesce_daemon} to detect whether all
+connections have been handled.

+@deftp {Enumeration} MHD_ConnectionInfoType
+Values of this enum are used to specify what information about a
+connection is desired.
+
+@table @code
+
+@item MHD_CONNECTION_INFO_CIPHER_ALGO
+What cipher algorithm is being used (HTTPS connections only).
+Takes no extra arguments.
+@code{NULL} is returned for non-HTTPS connections.
+
+@item MHD_CONNECTION_INFO_PROTOCOL,
+Takes no extra arguments. Allows finding out the TLS/SSL protocol used
+(HTTPS connections only).
+@code{NULL} is returned for non-HTTPS connections.
+
+@item MHD_CONNECTION_INFO_CLIENT_ADDRESS
+Returns information about the address of the client. Returns
+essentially a @code{struct sockaddr **} (since the API returns
+a @code{union MHD_ConnectionInfo *} and that union contains
+a @code{struct sockaddr *}).
+
+@item MHD_CONNECTION_INFO_GNUTLS_SESSION,
+Takes no extra arguments. Allows access to the underlying GNUtls session,
+including access to the underlying GNUtls client certificate
+(HTTPS connections only). Takes no extra arguments.
+@code{NULL} is returned for non-HTTPS connections.
+
+@item MHD_CONNECTION_INFO_GNUTLS_CLIENT_CERT,
+Dysfunctional (never implemented, deprecated). Use
+MHD_CONNECTION_INFO_GNUTLS_SESSION to get the @code{gnutls_session_t}
+and then call @code{gnutls_certificate_get_peers()}.
+
+@item MHD_CONNECTION_INFO_DAEMON
+Returns information about @code{struct MHD_Daemon} which manages
+this connection.
+
+@item MHD_CONNECTION_INFO_CONNECTION_FD
+Returns the file descriptor (usually a TCP socket) associated with
+this connection (in the ``connect-fd'' member of the returned struct).
+Note that manipulating the descriptor directly can have problematic
+consequences (as in, break HTTP). Applications might use this access
+to manipulate TCP options, for example to set the ``TCP-NODELAY''
+option for COMET-like applications. Note that MHD will set TCP-CORK
+after sending the HTTP header and clear it after finishing the footers
+automatically (if the platform supports it). As the connection
+callbacks are invoked in between, those might be used to set different
+values for TCP-CORK and TCP-NODELAY in the meantime.
+
+@item MHD_CONNECTION_INFO_SOCKET_CONTEXT
+Returns the client-specific pointer to a @code{void *} that was
+(possibly) set during a @code{MHD_NotifyConnectionCallback} when the
+socket was first accepted. Note that this is NOT the same as the
+@code{con_cls} argument of the @code{MHD_AccessHandlerCallback}. The
+@code{con_cls} is fresh for each HTTP request, while the
+@code{socket_context} is fresh for each socket.

+% Please try the latest version of texinfo.tex before submitting bug

+% http://ftpmirror.gnu.org/texinfo/ (same, via a mirror), or

+%
+% Send bug reports to bug-texinfo@gnu.org. Please include including a

+%
+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution. For a simple
+% manual foo.texi, however, you can get away with this:
+% tex foo.texi
+% texindex foo.??
+% tex foo.texi
+% tex foo.texi
+% dvips foo.dvi -o # or whatever; this makes foo.ps.
+% The extra TeX runs get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
+%
+% It is possible to adapt texinfo.tex for other languages, to some
+% extent. You can get the existing language-specific files from the
+% full Texinfo distribution.

+% Output a mark which sets \thischapter, \thissection and \thiscolor.

+%
+% A mark contains a subexpression of the \ifcase ... \fi construct.

+%
+% Another complication is to let the user choose whether \thischapter

+% described on page 260 of The TeXbook. It involves outputting two

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble. Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+% @multitable @columnfractions .25 .3 .45
+% @item ...
+%
+% Numbers following @columnfractions are the percent of the total
+% current hsize to be used for each column. You may use as many
+% columns as desired.
+
+
+% Or use a template:
+% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+% @item ...
+% using the widest term desired in each column.
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab do not need to be on their own lines, but it will not hurt
+% if they are.
+
+% Sample multitable:
+
+% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+% @item first col stuff @tab second col stuff @tab third col
+% @item
+% first col stuff
+% @tab
+% second col stuff
+% @tab
+% third col
+% @item first col stuff @tab second col stuff
+% @tab Many paragraphs of text may be used in any column.
+%
+% They will wrap at the width determined by the template.
+% @item@tab@tab This will be in third column.
+% @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+% to baseline.
+% 0pt means it depends on current normal line spacing.

+#
+# AX_APPEND_COMPILE_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS])
+#
+# DESCRIPTION
+#
+# For every FLAG1, FLAG2 it is checked whether the compiler works with the
+# flag. If it does, the flag is added FLAGS-VARIABLE
+#
+# If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
+# CFLAGS) is used. During the check the flag is always added to the
+# current language's flags.
+#
+# If EXTRA-FLAGS is defined, it is added to the current language's default
+# flags (e.g. CFLAGS) when the check is done. The check is thus made with
+# the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to
+# force the compiler to issue an error when a bad flag is given.
+#
+# NOTE: This macro depends on the AX_APPEND_FLAG and
+# AX_CHECK_COMPILE_FLAG. Please keep this macro in sync with
+# AX_APPEND_LINK_FLAGS.

+# AX_HAVE_EPOLL_PWAIT([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
+#
+# DESCRIPTION
+#
+# This macro determines whether the system supports the epoll I/O event
+# interface. A neat usage example would be:
+#
+# AX_HAVE_EPOLL(
+# [AX_CONFIG_FEATURE_ENABLE(epoll)],
+# [AX_CONFIG_FEATURE_DISABLE(epoll)])
+# AX_CONFIG_FEATURE(
+# [epoll], [This platform supports epoll(7)],
+# [HAVE_EPOLL], [This platform supports epoll(7).])
+#
+# The epoll interface was added to the Linux kernel in version 2.5.45, and
+# the macro verifies that a kernel newer than this is installed. This
+# check is somewhat unreliable if <linux/version.h> doesn't match the
+# running kernel, but it is necessary regardless, because glibc comes with
+# stubs for the epoll_create(), epoll_wait(), etc. that allow programs to
+# compile and link even if the kernel is too old; the problem would then
+# be detected only at runtime.
+#
+# Linux kernel version 2.6.19 adds the epoll_pwait() call in addition to
+# epoll_wait(). The availability of that function can be tested with the
+# second macro. Generally speaking, it is safe to assume that
+# AX_HAVE_EPOLL would succeed if AX_HAVE_EPOLL_PWAIT has, but not the
+# other way round.

+# SYNOPSIS
+#
+# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+# This macro figures out how to build C programs using POSIX threads. It
+# sets the PTHREAD_LIBS output variable to the threads library and linker
+# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+# flags that are needed. (The user can also force certain compiler
+# flags/libs to be tested by setting these environment variables.)
+#
+# Also sets PTHREAD_CC to any special C compiler that is needed for
+# multi-threaded programs (defaults to the value of CC otherwise). (This
+# is necessary on AIX to use the special cc_r compiler alias.)
+#
+# NOTE: You are assumed to not only compile your program with these flags,
+# but also link it with them as well. e.g. you should link with
+# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+# If you are only building threads programs, you may wish to use these
+# variables in your default LIBS, CFLAGS, and CC:
+#
+# LIBS="$PTHREAD_LIBS $LIBS"
+# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+# CC="$PTHREAD_CC"
+#
+# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
+# (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+# PTHREAD_CFLAGS.
+#
+# ACTION-IF-FOUND is a list of shell commands to run if a threads library
+# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+# is not found. If ACTION-IF-FOUND is not specified, the default action
+# will define HAVE_PTHREAD.
+#
+# Please let the authors know if this macro fails on any platform, or if
+# you have any other suggestions or comments. This macro was based on work
+# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+# Alejandro Forero Cuervo to the autoconf macro repository. We are also
+# grateful for the helpful feedback of numerous users.

+# AX_REQUIRE_DEFINED is a simple helper for making sure other macros have

+# LIBCURL_CHECK_CONFIG ([DEFAULT-ACTION], [MINIMUM-VERSION],
+# [ACTION-IF-YES], [ACTION-IF-NO])
+# ----------------------------------------------------------
+# David Shaw <dshaw@jabberwocky.com> May-09-2006
+#
+# Checks for libcurl. DEFAULT-ACTION is the string yes or no to
+# specify whether to default to --with-libcurl or --without-libcurl.
+# If not supplied, DEFAULT-ACTION is yes. MINIMUM-VERSION is the
+# minimum version of libcurl to accept. Pass the version as a regular
+# version number like 7.10.1. If not supplied, any version is
+# accepted. ACTION-IF-YES is a list of shell commands to run if
+# libcurl was successfully found and passed the various tests.
+# ACTION-IF-NO is a list of shell commands that are run otherwise.
+# Note that using --without-libcurl does run ACTION-IF-NO.
+#
+# This macro #defines HAVE_LIBCURL if a working libcurl setup is
+# found, and sets @LIBCURL@ and @LIBCURL_CPPFLAGS@ to the necessary
+# values. Other useful defines are LIBCURL_FEATURE_xxx where xxx are
+# the various features supported by libcurl, and LIBCURL_PROTOCOL_yyy
+# where yyy are the various protocols supported by libcurl. Both xxx
+# and yyy are capitalized. See the list of AH_TEMPLATEs at the top of
+# the macro for the complete list of possible defines. Shell
+# variables $libcurl_feature_xxx and $libcurl_protocol_yyy are also
+# defined to 'yes' for those features and protocols that were found.
+# Note that xxx and yyy keep the same capitalization as in the
+# curl-config list (e.g. it's "HTTP" and not "http").
+#
+# Users may override the detected values by doing something like:
+# LIBCURL="-lcurl" LIBCURL_CPPFLAGS="-I/usr/myinclude" ./configure
+#
+# For the sake of sanity, this macro assumes that any libcurl that is
+# found is after version 7.7.2, the first version that included the
+# curl-config script. Note that it is very important for people
+# packaging binary versions of libcurl to include this script!
+# Without curl-config, we can only guess what protocols are available,
+# or use curl_version_info to figure it out at runtime.

+
+ SPDY Protocol
+ draft-mbelshe-httpbis-spdy-00
+
+Abstract
+
+ This document describes SPDY, a protocol designed for low-latency
+ transport of content over the World Wide Web. SPDY introduces two
+ layers of protocol. The lower layer is a general purpose framing
+ layer which can be used atop a reliable transport (likely TCP) for
+ multiplexed, prioritized, and compressed data communication of many
+ concurrent streams. The upper layer of the protocol provides HTTP-
+ like RFC2616 [RFC2616] semantics for compatibility with existing HTTP
+ application servers.
+
+Status of this Memo
+
+ This Internet-Draft is submitted in full conformance with the
+ provisions of BCP 78 and BCP 79.
+
+ Internet-Drafts are working documents of the Internet Engineering
+ Task Force (IETF). Note that other groups may also distribute
+ working documents as Internet-Drafts. The list of current Internet-
+ Drafts is at http://datatracker.ietf.org/drafts/current/.

+
+
+1. Overview
+
+ One of the bottlenecks of HTTP implementations is that HTTP relies on
+ multiple connections for concurrency. This causes several problems,
+ including additional round trips for connection setup, slow-start
+ delays, and connection rationing by the client, where it tries to
+ avoid opening too many connections to any single server. HTTP
+ pipelining helps some, but only achieves partial multiplexing. In
+ addition, pipelining has proven non-deployable in existing browsers
+ due to intermediary interference.
+
+ SPDY adds a framing layer for multiplexing multiple, concurrent
+ streams across a single TCP connection (or any reliable transport
+ stream). The framing layer is optimized for HTTP-like request-
+ response streams, such that applications which run over HTTP today
+ can work over SPDY with little or no change on behalf of the web
+ application writer.
+
+ The SPDY session offers four improvements over HTTP:
+
+ Multiplexed requests: There is no limit to the number of requests
+ that can be issued concurrently over a single SPDY connection.
+
+ Prioritized requests: Clients can request certain resources to be
+ delivered first. This avoids the problem of congesting the
+ network channel with non-critical resources when a high-priority
+ request is pending.
+
+ Compressed headers: Clients today send a significant amount of
+ redundant data in the form of HTTP headers. Because a single web
+ page may require 50 or 100 subrequests, this data is significant.
+
+ Server pushed streams: Server Push enables content to be pushed
+ from servers to clients without a request.
+
+ SPDY attempts to preserve the existing semantics of HTTP. All
+ features such as cookies, ETags, Vary headers, Content-Encoding
+ negotiations, etc work as they do with HTTP; SPDY only replaces the
+ way the data is written to the network.
+
+1.1. Document Organization
+
+ The SPDY Specification is split into two parts: a framing layer
+ (Section 2), which multiplexes a TCP connection into independent,
+ length-prefixed frames, and an HTTP layer (Section 3), which
+ specifies the mechanism for overlaying HTTP request/response pairs on
+ top of the framing layer. While some of the framing layer concepts
+ are isolated from the HTTP layer, building a generic framing layer
+
+
+
+Belshe & Peon Expires August 4, 2012 [Page 4]
+
+Internet-Draft SPDY Feb 2012
+
+
+ has not been a goal. The framing layer is tailored to the needs of
+ the HTTP protocol and server push.
+
+1.2. Definitions
+
+ client: The endpoint initiating the SPDY session.
+
+ connection: A transport-level connection between two endpoints.
+
+ endpoint: Either the client or server of a connection.
+
+ frame: A header-prefixed sequence of bytes sent over a SPDY
+ session.
+
+ server: The endpoint which did not initiate the SPDY session.
+
+ session: A synonym for a connection.
+
+ session error: An error on the SPDY session.
+
+ stream: A bi-directional flow of bytes across a virtual channel
+ within a SPDY session.
+
+ stream error: An error on an individual SPDY stream.

+
+2. SPDY Framing Layer
+
+2.1. Session (Connections)
+
+ The SPDY framing layer (or "session") runs atop a reliable transport
+ layer such as TCP [RFC0793]. The client is the TCP connection
+ initiator. SPDY connections are persistent connections.
+
+ For best performance, it is expected that clients will not close open
+ connections until the user navigates away from all web pages
+ referencing a connection, or until the server closes the connection.
+ Servers are encouraged to leave connections open for as long as
+ possible, but can terminate idle connections if necessary. When
+ either endpoint closes the transport-level connection, it MUST first
+ send a GOAWAY (Section 2.6.6) frame so that the endpoints can
+ reliably determine if requests finished before the close.
+
+2.2. Framing
+
+ Once the connection is established, clients and servers exchange
+ framed messages. There are two types of frames: control frames
+ (Section 2.2.1) and data frames (Section 2.2.2). Frames always have
+ a common header which is 8 bytes in length.
+
+ The first bit is a control bit indicating whether a frame is a
+ control frame or data frame. Control frames carry a version number,
+ a frame type, flags, and a length. Data frames contain the stream
+ ID, flags, and the length for the payload carried after the common
+ header. The simple header is designed to make reading and writing of
+ frames easy.
+
+ All integer values, including length, version, and type, are in
+ network byte order. SPDY does not enforce alignment of types in
+ dynamically sized frames.
+
+2.2.1. Control frames
+
+ +----------------------------------+
+ |C| Version(15bits) | Type(16bits) |
+ +----------------------------------+
+ | Flags (8) | Length (24 bits) |
+ +----------------------------------+
+ | Data |
+ +----------------------------------+
+
+ Control bit: The 'C' bit is a single bit indicating if this is a
+ control message. For control frames this value is always 1.
+
+
+
+
+Belshe & Peon Expires August 4, 2012 [Page 6]
+
+Internet-Draft SPDY Feb 2012
+
+
+ Version: The version number of the SPDY protocol. This document
+ describes SPDY version 3.
+
+ Type: The type of control frame. See Control Frames for the complete
+ list of control frames.
+
+ Flags: Flags related to this frame. Flags for control frames and
+ data frames are different.
+
+ Length: An unsigned 24-bit value representing the number of bytes
+ after the length field.
+
+ Data: data associated with this control frame. The format and length
+ of this data is controlled by the control frame type.
+
+ Control frame processing requirements:
+
+ Note that full length control frames (16MB) can be large for
+ implementations running on resource-limited hardware. In such
+ cases, implementations MAY limit the maximum length frame
+ supported. However, all implementations MUST be able to receive
+ control frames of at least 8192 octets in length.
+
+2.2.2. Data frames
+
+ +----------------------------------+
+ |C| Stream-ID (31bits) |
+ +----------------------------------+
+ | Flags (8) | Length (24 bits) |
+ +----------------------------------+
+ | Data |
+ +----------------------------------+
+
+ Control bit: For data frames this value is always 0.
+
+ Stream-ID: A 31-bit value identifying the stream.
+
+ Flags: Flags related to this frame. Valid flags are:
+
+ 0x01 = FLAG_FIN - signifies that this frame represents the last
+ frame to be transmitted on this stream. See Stream Close
+ (Section 2.3.7) below.
+
+ 0x02 = FLAG_COMPRESS - indicates that the data in this frame has
+ been compressed.
+
+ Length: An unsigned 24-bit value representing the number of bytes
+ after the length field. The total size of a data frame is 8 bytes +
+
+
+
+Belshe & Peon Expires August 4, 2012 [Page 7]
+
+Internet-Draft SPDY Feb 2012
+
+
+ length. It is valid to have a zero-length data frame.
+
+ Data: The variable-length data payload; the length was defined in the
+ length field.
+
+ Data frame processing requirements:
+
+ If an endpoint receives a data frame for a stream-id which is not
+ open and the endpoint has not sent a GOAWAY (Section 2.6.6) frame,
+ it MUST send issue a stream error (Section 2.4.2) with the error
+ code INVALID_STREAM for the stream-id.
+
+ If the endpoint which created the stream receives a data frame
+ before receiving a SYN_REPLY on that stream, it is a protocol
+ error, and the recipient MUST issue a stream error (Section 2.4.2)
+ with the status code PROTOCOL_ERROR for the stream-id.
+
+ Implementors note: If an endpoint receives multiple data frames
+ for invalid stream-ids, it MAY close the session.
+
+ All SPDY endpoints MUST accept compressed data frames.
+ Compression of data frames is always done using zlib compression.
+ Each stream initializes and uses its own compression context
+ dedicated to use within that stream. Endpoints are encouraged to
+ use application level compression rather than SPDY stream level
+ compression.
+
+ Each SPDY stream sending compressed frames creates its own zlib
+ context for that stream, and these compression contexts MUST be
+ distinct from the compression contexts used with SYN_STREAM/
+ SYN_REPLY/HEADER compression. (Thus, if both endpoints of a
+ stream are compressing data on the stream, there will be two zlib
+ contexts, one for sending and one for receiving).
+
+2.3. Streams
+
+ Streams are independent sequences of bi-directional data divided into
+ frames with several properties:
+
+ Streams may be created by either the client or server.
+
+ Streams optionally carry a set of name/value header pairs.
+
+ Streams can concurrently send data interleaved with other streams.
+
+ Streams may be cancelled.
+
+
+
+
+

+
+Internet-Draft SPDY Feb 2012
+
+
+2.3.1. Stream frames
+
+ SPDY defines 3 control frames to manage the lifecycle of a stream:
+
+ SYN_STREAM - Open a new stream
+
+ SYN_REPLY - Remote acknowledgement of a new, open stream
+
+ RST_STREAM - Close a stream
+
+2.3.2. Stream creation
+
+ A stream is created by sending a control frame with the type set to
+ SYN_STREAM (Section 2.6.1). If the server is initiating the stream,
+ the Stream-ID must be even. If the client is initiating the stream,
+ the Stream-ID must be odd. 0 is not a valid Stream-ID. Stream-IDs
+ from each side of the connection must increase monotonically as new
+ streams are created. E.g. Stream 2 may be created after stream 3,
+ but stream 7 must not be created after stream 9. Stream IDs do not
+ wrap: when a client or server cannot create a new stream id without
+ exceeding a 31 bit value, it MUST NOT create a new stream.
+
+ The stream-id MUST increase with each new stream. If an endpoint
+ receives a SYN_STREAM with a stream id which is less than any
+ previously received SYN_STREAM, it MUST issue a session error
+ (Section 2.4.1) with the status PROTOCOL_ERROR.
+
+ It is a protocol error to send two SYN_STREAMs with the same
+ stream-id. If a recipient receives a second SYN_STREAM for the same
+ stream, it MUST issue a stream error (Section 2.4.2) with the status
+ code PROTOCOL_ERROR.
+
+ Upon receipt of a SYN_STREAM, the recipient can reject the stream by
+ sending a stream error (Section 2.4.2) with the error code
+ REFUSED_STREAM. Note, however, that the creating endpoint may have
+ already sent additional frames for that stream which cannot be
+ immediately stopped.
+
+ Once the stream is created, the creator may immediately send HEADERS
+ or DATA frames for that stream, without needing to wait for the
+ recipient to acknowledge.
+
+2.3.2.1. Unidirectional streams
+
+ When an endpoint creates a stream with the FLAG_UNIDIRECTIONAL flag
+ set, it creates a unidirectional stream which the creating endpoint
+ can use to send frames, but the receiving endpoint cannot. The
+ receiving endpoint is implicitly already in the half-closed
+
+
+
+Belshe & Peon Expires August 4, 2012 [Page 9]
+
+Internet-Draft SPDY Feb 2012
+
+
+ (Section 2.3.6) state.
+
+2.3.2.2. Bidirectional streams
+
+ SYN_STREAM frames which do not use the FLAG_UNIDIRECTIONAL flag are
+ bidirectional streams. Both endpoints can send data on a bi-
+ directional stream.
+
+2.3.3. Stream priority
+
+ The creator of a stream assigns a priority for that stream. Priority
+ is represented as an integer from 0 to 7. 0 represents the highest
+ priority and 7 represents the lowest priority.
+
+ The sender and recipient SHOULD use best-effort to process streams in
+ the order of highest priority to lowest priority.
+
+2.3.4. Stream headers
+
+ Streams carry optional sets of name/value pair headers which carry
+ metadata about the stream. After the stream has been created, and as
+ long as the sender is not closed (Section 2.3.7) or half-closed
+ (Section 2.3.6), each side may send HEADERS frame(s) containing the
+ header data. Header data can be sent in multiple HEADERS frames, and
+ HEADERS frames may be interleaved with data frames.
+
+2.3.5. Stream data exchange
+
+ Once a stream is created, it can be used to send arbitrary amounts of
+ data. Generally this means that a series of data frames will be sent
+ on the stream until a frame containing the FLAG_FIN flag is set. The
+ FLAG_FIN can be set on a SYN_STREAM (Section 2.6.1), SYN_REPLY
+ (Section 2.6.2), HEADERS (Section 2.6.7) or a DATA (Section 2.2.2)
+ frame. Once the FLAG_FIN has been sent, the stream is considered to
+ be half-closed.
+
+2.3.6. Stream half-close
+
+ When one side of the stream sends a frame with the FLAG_FIN flag set,
+ the stream is half-closed from that endpoint. The sender of the
+ FLAG_FIN MUST NOT send further frames on that stream. When both
+ sides have half-closed, the stream is closed.
+
+ If an endpoint receives a data frame after the stream is half-closed
+ from the sender (e.g. the endpoint has already received a prior frame
+ for the stream with the FIN flag set), it MUST send a RST_STREAM to
+ the sender with the status STREAM_ALREADY_CLOSED.
+
+
+
+
+Belshe & Peon Expires August 4, 2012 [Page 10]
+
+Internet-Draft SPDY Feb 2012
+
+
+2.3.7. Stream close
+
+ There are 3 ways that streams can be terminated:
+
+ Normal termination: Normal stream termination occurs when both
+ sender and recipient have half-closed the stream by sending a
+ FLAG_FIN.
+
+ Abrupt termination: Either the client or server can send a
+ RST_STREAM control frame at any time. A RST_STREAM contains an
+ error code to indicate the reason for failure. When a RST_STREAM
+ is sent from the stream originator, it indicates a failure to
+ complete the stream and that no further data will be sent on the
+ stream. When a RST_STREAM is sent from the stream recipient, the
+ sender, upon receipt, should stop sending any data on the stream.
+ The stream recipient should be aware that there is a race between
+ data already in transit from the sender and the time the
+ RST_STREAM is received. See Stream Error Handling (Section 2.4.2)
+
+ TCP connection teardown: If the TCP connection is torn down while
+ un-closed streams exist, then the endpoint must assume that the
+ stream was abnormally interrupted and may be incomplete.
+
+ If an endpoint receives a data frame after the stream is closed, it
+ must send a RST_STREAM to the sender with the status PROTOCOL_ERROR.
+
+2.4. Error Handling
+
+ The SPDY framing layer has only two types of errors, and they are
+ always handled consistently. Any reference in this specification to
+ "issue a session error" refers to Section 2.4.1. Any reference to
+ "issue a stream error" refers to Section 2.4.2.
+
+2.4.1. Session Error Handling
+
+ A session error is any error which prevents further processing of the
+ framing layer or which corrupts the session compression state. When
+ a session error occurs, the endpoint encountering the error MUST
+ first send a GOAWAY (Section 2.6.6) frame with the stream id of most
+ recently received stream from the remote endpoint, and the error code
+ for why the session is terminating. After sending the GOAWAY frame,
+ the endpoint MUST close the TCP connection.
+
+ Note that the session compression state is dependent upon both
+ endpoints always processing all compressed data. If an endpoint
+ partially processes a frame containing compressed data without
+ updating compression state properly, future control frames which use
+ compression will be always be errored. Implementations SHOULD always
+
+
+
+Belshe & Peon Expires August 4, 2012 [Page 11]
+
+Internet-Draft SPDY Feb 2012
+
+
+ try to process compressed data so that errors which could be handled
+ as stream errors do not become session errors.
+
+ Note that because this GOAWAY is sent during a session error case, it
+ is possible that the GOAWAY will not be reliably received by the
+ receiving endpoint. It is a best-effort attempt to communicate with
+ the remote about why the session is going down.
+
+2.4.2. Stream Error Handling
+
+ A stream error is an error related to a specific stream-id which does
+ not affect processing of other streams at the framing layer. Upon a
+ stream error, the endpoint MUST send a RST_STREAM (Section 2.6.3)
+ frame which contains the stream id of the stream where the error
+ occurred and the error status which caused the error. After sending
+ the RST_STREAM, the stream is closed to the sending endpoint. After
+ sending the RST_STREAM, if the sender receives any frames other than
+ a RST_STREAM for that stream id, it will result in sending additional
+ RST_STREAM frames. An endpoint MUST NOT send a RST_STREAM in
+ response to an RST_STREAM, as doing so would lead to RST_STREAM
+ loops. Sending a RST_STREAM does not cause the SPDY session to be
+ closed.
+
+ If an endpoint has multiple RST_STREAM frames to send in succession
+ for the same stream-id and the same error code, it MAY coalesce them
+ into a single RST_STREAM frame. (This can happen if a stream is
+ closed, but the remote sends multiple data frames. There is no
+ reason to send a RST_STREAM for each frame in succession).
+
+2.5. Data flow
+
+ Because TCP provides a single stream of data on which SPDY
+ multiplexes multiple logical streams, clients and servers must
+ intelligently interleave data messages for concurrent sessions.
+
+2.6. Control frame types
+
+2.6.1. SYN_STREAM
+
+ The SYN_STREAM control frame allows the sender to asynchronously
+ create a stream between the endpoints. See Stream Creation
+ (Section 2.3.2)

+
+ If an endpoint receives multiple SYN_REPLY frames for the same active
+ stream ID, it MUST issue a stream error (Section 2.4.2) with the
+ error code STREAM_IN_USE.
+
+ Name/Value Header Block: A set of name/value pairs carried as part of
+ the SYN_STREAM. see Name/Value Header Block (Section 2.6.10).
+
+ If an endpoint receives a SYN_REPLY which is larger than the
+ implementation supports, it MAY send a RST_STREAM with error code
+ FRAME_TOO_LARGE. All implementations MUST support the minimum size
+ limits defined in the Control Frames section (Section 2.2.1).
+
+2.6.3. RST_STREAM
+
+ The RST_STREAM frame allows for abnormal termination of a stream.
+ When sent by the creator of a stream, it indicates the creator wishes
+ to cancel the stream. When sent by the recipient of a stream, it
+ indicates an error or that the recipient did not want to accept the
+ stream, so the stream should be closed.

+
+ 7 - FLOW_CONTROL_ERROR. The endpoint detected that its peer

+
+ 8 - STREAM_IN_USE. The endpoint received a SYN_REPLY for a stream

+ will be out-of-sync with the other endpoint. In this case,
+ senders of FRAME_TOO_LARGE MUST close the session.
+
+ Note: 0 is not a valid status code for a RST_STREAM.
+
+ After receiving a RST_STREAM on a stream, the recipient must not send
+ additional frames for that stream, and the stream moves into the
+ closed state.
+
+2.6.4. SETTINGS
+
+ A SETTINGS frame contains a set of id/value pairs for communicating
+ configuration data about how the two endpoints may communicate.
+ SETTINGS frames can be sent at any time by either endpoint, are
+ optionally sent, and are fully asynchronous. When the server is the
+ sender, the sender can request that configuration data be persisted
+ by the client across SPDY sessions and returned to the server in
+ future communications.

+
+

+
+
+ Persistence of SETTINGS ID/Value pairs is done on a per origin/IP
+ pair (the "origin" is the set of scheme, host, and port from the URI.
+ See [RFC6454]). That is, when a client connects to a server, and the
+ server persists settings within the client, the client SHOULD return
+ the persisted settings on future connections to the same origin AND
+ IP address and TCP port. Clients MUST NOT request servers to use the
+ persistence features of the SETTINGS frames, and servers MUST ignore
+ persistence related flags sent by a client.

+ this frame contains ID/Value pairs with the
+ FLAG_SETTINGS_PERSIST_VALUE set, then the client will first clear its
+ existing, persisted settings, and then persist the values with the
+ flag set which are contained within this frame. Because persistence
+ is only implemented on the client, this flag can only be used when
+ the sender is the server.
+
+ Length: An unsigned 24-bit value representing the number of bytes

+ Value and return it in future SETTINGS frames sent from the
+ sender to this recipient. Because persistence is only
+ implemented on the client, this flag is only sent by the
+ server.
+
+ FLAG_SETTINGS_PERSISTED (0x2): When set, the sender is
+ notifying the recipient that this ID/Value pair was previously
+ sent to the sender by the recipient with the
+ FLAG_SETTINGS_PERSIST_VALUE, and the sender is returning it.
+ Because persistence is only implemented on the client, this
+ flag is only sent by the client.
+
+ Defined IDs:
+
+ 1 - SETTINGS_UPLOAD_BANDWIDTH allows the sender to send its
+ expected upload bandwidth on this channel. This number is an
+ estimate. The value should be the integral number of kilobytes
+ per second that the sender predicts as an expected maximum
+ upload channel capacity.
+
+ 2 - SETTINGS_DOWNLOAD_BANDWIDTH allows the sender to send its
+ expected download bandwidth on this channel. This number is an
+ estimate. The value should be the integral number of kilobytes
+ per second that the sender predicts as an expected maximum
+ download channel capacity.
+
+ 3 - SETTINGS_ROUND_TRIP_TIME allows the sender to send its
+ expected round-trip-time on this channel. The round trip time
+ is defined as the minimum amount of time to send a control
+ frame from this client to the remote and receive a response.
+ The value is represented in milliseconds.
+
+ 4 - SETTINGS_MAX_CONCURRENT_STREAMS allows the sender to inform
+ the remote endpoint the maximum number of concurrent streams
+ which it will allow. By default there is no limit. For
+ implementors it is recommended that this value be no smaller
+ than 100.
+
+ 5 - SETTINGS_CURRENT_CWND allows the sender to inform the
+ remote endpoint of the current TCP CWND value.
+
+ 6 - SETTINGS_DOWNLOAD_RETRANS_RATE allows the sender to inform
+ the remote endpoint the retransmission rate (bytes
+ retransmitted / total bytes transmitted).
+
+ 7 - SETTINGS_INITIAL_WINDOW_SIZE allows the sender to inform
+ the remote endpoint the initial window size (in bytes) for new
+ streams.

+
+
+ 8 - SETTINGS_CLIENT_CERTIFICATE_VECTOR_SIZE allows the server
+ to inform the client if the new size of the client certificate
+ vector.
+
+ Value: A 32-bit value.
+
+ The message is intentionally extensible for future information which
+ may improve client-server communications. The sender does not need
+ to send every type of ID/value. It must only send those for which it
+ has accurate values to convey. When multiple ID/value pairs are
+ sent, they should be sent in order of lowest id to highest id. A
+ single SETTINGS frame MUST not contain multiple values for the same
+ ID. If the recipient of a SETTINGS frame discovers multiple values
+ for the same ID, it MUST ignore all values except the first one.
+
+ A server may send multiple SETTINGS frames containing different ID/
+ Value pairs. When the same ID/Value is sent twice, the most recent
+ value overrides any previously sent values. If the server sends IDs
+ 1, 2, and 3 with the FLAG_SETTINGS_PERSIST_VALUE in a first SETTINGS
+ frame, and then sends IDs 4 and 5 with the
+ FLAG_SETTINGS_PERSIST_VALUE, when the client returns the persisted
+ state on its next SETTINGS frame, it SHOULD send all 5 settings (1,
+ 2, 3, 4, and 5 in this example) to the server.
+
+2.6.5. PING
+
+ The PING control frame is a mechanism for measuring a minimal round-
+ trip time from the sender. It can be sent from the client or the
+ server. Recipients of a PING frame should send an identical frame to
+ the sender as soon as possible (if there is other pending data
+ waiting to be sent, PING should take highest priority). Each ping
+ sent by a sender should use a unique ID.

+
+Internet-Draft SPDY Feb 2012
+
+
+ ID: A unique ID for this ping, represented as an unsigned 32 bit
+ value. When the client initiates a ping, it must use an odd numbered
+ ID. When the server initiates a ping, it must use an even numbered
+ ping. Use of odd/even IDs is required in order to avoid accidental
+ looping on PINGs (where each side initiates an identical PING at the
+ same time).
+
+ Note: If a sender uses all possible PING ids (e.g. has sent all 2^31
+ possible IDs), it can wrap and start re-using IDs.
+
+ If a server receives an even numbered PING which it did not initiate,
+ it must ignore the PING. If a client receives an odd numbered PING
+ which it did not initiate, it must ignore the PING.
+
+2.6.6. GOAWAY
+
+ The GOAWAY control frame is a mechanism to tell the remote side of
+ the connection to stop creating streams on this session. It can be
+ sent from the client or the server. Once sent, the sender will not
+ respond to any new SYN_STREAMs on this session. Recipients of a
+ GOAWAY frame must not send additional streams on this session,
+ although a new session can be established for new streams. The
+ purpose of this message is to allow an endpoint to gracefully stop
+ accepting new streams (perhaps for a reboot or maintenance), while
+ still finishing processing of previously established streams.
+
+ There is an inherent race condition between an endpoint sending
+ SYN_STREAMs and the remote sending a GOAWAY message. To deal with
+ this case, the GOAWAY contains a last-stream-id indicating the
+ stream-id of the last stream which was created on the sending
+ endpoint in this session. If the receiver of the GOAWAY sent new
+ SYN_STREAMs for sessions after this last-stream-id, they were not
+ processed by the server and the receiver may treat the stream as
+ though it had never been created at all (hence the receiver may want
+ to re-create the stream later on a new session).
+
+ Endpoints should always send a GOAWAY message before closing a
+ connection so that the remote can know whether a stream has been
+ partially processed or not. (For example, if an HTTP client sends a
+ POST at the same time that a server closes a connection, the client
+ cannot know if the server started to process that POST request if the
+ server does not send a GOAWAY frame to indicate where it stopped
+ working).
+
+ After sending a GOAWAY message, the sender must ignore all SYN_STREAM
+ frames for new streams.

+
+ 0x01 = FLAG_FIN - marks this frame as the last frame to be
+ transmitted on this stream and puts the sender in the half-closed
+ (Section 2.3.6) state.
+
+ Length: An unsigned 24 bit value representing the number of bytes

+ (when the number of name value pairs is 0).
+
+ Stream-ID: The stream this HEADERS block is associated with.
+
+ Name/Value Header Block: A set of name/value pairs carried as part of
+ the SYN_STREAM. see Name/Value Header Block (Section 2.6.10).
+
+2.6.8. WINDOW_UPDATE
+
+ The WINDOW_UPDATE control frame is used to implement per stream flow
+ control in SPDY. Flow control in SPDY is per hop, that is, only
+ between the two endpoints of a SPDY connection. If there are one or
+ more intermediaries between the client and the origin server, flow
+ control signals are not explicitly forwarded by the intermediaries.
+ (However, throttling of data transfer by any recipient may have the
+ effect of indirectly propagating flow control information upstream
+ back to the original sender.) Flow control only applies to the data
+ portion of data frames. Recipients must buffer all control frames.
+ If a recipient fails to buffer an entire control frame, it MUST issue
+ a stream error (Section 2.4.2) with the status code
+ FLOW_CONTROL_ERROR for the stream.
+
+
+
+Belshe & Peon Expires August 4, 2012 [Page 22]
+
+Internet-Draft SPDY Feb 2012
+
+
+ Flow control in SPDY is implemented by a data transfer window kept by
+ the sender of each stream. The data transfer window is a simple
+ uint32 that indicates how many bytes of data the sender can transmit.
+ After a stream is created, but before any data frames have been
+ transmitted, the sender begins with the initial window size. This
+ window size is a measure of the buffering capability of the
+ recipient. The sender must not send a data frame with data length
+ greater than the transfer window size. After sending each data
+ frame, the sender decrements its transfer window size by the amount
+ of data transmitted. When the window size becomes less than or equal
+ to 0, the sender must pause transmitting data frames. At the other
+ end of the stream, the recipient sends a WINDOW_UPDATE control back
+ to notify the sender that it has consumed some data and freed up
+ buffer space to receive more data.

+ +----------------------------------+
+
+ Control bit: The control bit is always 1 for this message.
+
+ Version: The SPDY version number.
+
+ Type: The message type for a WINDOW_UPDATE message is 9.
+
+ Length: The length field is always 8 for this frame (there are 8
+ bytes after the length field).
+
+ Stream-ID: The stream ID that this WINDOW_UPDATE control frame is
+ for.
+
+ Delta-Window-Size: The additional number of bytes that the sender can
+ transmit in addition to existing remaining window size. The legal
+ range for this field is 1 to 2^31 - 1 (0x7fffffff) bytes.
+
+ The window size as kept by the sender must never exceed 2^31
+ (although it can become negative in one special case). If a sender
+ receives a WINDOW_UPDATE that causes the its window size to exceed
+ this limit, it must send RST_STREAM with status code
+ FLOW_CONTROL_ERROR to terminate the stream.
+
+ When a SPDY connection is first established, the default initial
+
+
+
+Belshe & Peon Expires August 4, 2012 [Page 23]
+
+Internet-Draft SPDY Feb 2012
+
+
+ window size for all streams is 64KB. An endpoint can use the
+ SETTINGS control frame to adjust the initial window size for the
+ connection. That is, its peer can start out using the 64KB default
+ initial window size when sending data frames before receiving the
+ SETTINGS. Because SETTINGS is asynchronous, there may be a race
+ condition if the recipient wants to decrease the initial window size,
+ but its peer immediately sends 64KB on the creation of a new
+ connection, before waiting for the SETTINGS to arrive. This is one
+ case where the window size kept by the sender will become negative.
+ Once the sender detects this condition, it must stop sending data
+ frames and wait for the recipient to catch up. The recipient has two
+ choices:
+
+ immediately send RST_STREAM with FLOW_CONTROL_ERROR status code.
+
+ allow the head of line blocking (as there is only one stream for
+ the session and the amount of data in flight is bounded by the
+ default initial window size), and send WINDOW_UPDATE as it
+ consumes data.
+
+ In the case of option 2, both sides must compute the window size
+ based on the initial window size in the SETTINGS. For example, if
+ the recipient sets the initial window size to be 16KB, and the sender
+ sends 64KB immediately on connection establishment, the sender will
+ discover its window size is -48KB on receipt of the SETTINGS. As the
+ recipient consumes the first 16KB, it must send a WINDOW_UPDATE of
+ 16KB back to the sender. This interaction continues until the
+ sender's window size becomes positive again, and it can resume
+ transmitting data frames.
+
+ After the recipient reads in a data frame with FLAG_FIN that marks
+ the end of the data stream, it should not send WINDOW_UPDATE frames
+ as it consumes the last data frame. A sender should ignore all the
+ WINDOW_UPDATE frames associated with the stream after it send the
+ last frame for the stream.
+
+ The data frames from the sender and the WINDOW_UPDATE frames from the
+ recipient are completely asynchronous with respect to each other.
+ This property allows a recipient to aggressively update the window
+ size kept by the sender to prevent the stream from stalling.
+
+2.6.9. CREDENTIAL
+
+ The CREDENTIAL control frame is used by the client to send additional
+ client certificates to the server. A SPDY client may decide to send
+ requests for resources from different origins on the same SPDY
+ session if it decides that that server handles both origins. For
+ example if the IP address associated with both hostnames matches and
+
+
+
+Belshe & Peon Expires August 4, 2012 [Page 24]
+
+Internet-Draft SPDY Feb 2012
+
+
+ the SSL server certificate presented in the initial handshake is
+ valid for both hostnames. However, because the SSL connection can
+ contain at most one client certificate, the client needs a mechanism
+ to send additional client certificates to the server.
+
+ The server is required to maintain a vector of client certificates
+ associated with a SPDY session. When the client needs to send a
+ client certificate to the server, it will send a CREDENTIAL frame
+ that specifies the index of the slot in which to store the
+ certificate as well as proof that the client posesses the
+ corresponding private key. The initial size of this vector must be
+ 8. If the client provides a client certificate during the first TLS
+ handshake, the contents of this certificate must be copied into the
+ first slot (index 1) in the CREDENTIAL vector, though it may be
+ overwritten by subsequent CREDENTIAL frames. The server must
+ exclusively use the CREDNETIAL vector when evaluating the client
+ certificates associated with an origin. The server may change the
+ size of this vector by sending a SETTINGS frame with the setting
+ SETTINGS_CLIENT_CERTIFICATE_VECTOR_SIZE value specified. In the
+ event that the new size is smaller than the current size, truncation
+ occurs preserving lower-index slots as possible.
+
+ TLS renegotiation with client authentication is incompatible with
+ SPDY given the multiplexed nature of SPDY. Specifically, imagine
+ that the client has 2 requests outstanding to the server for two
+ different pages (in different tabs). When the renegotiation + client
+ certificate request comes in, the browser is unable to determine
+ which resource triggered the client certificate request, in order to
+ prompt the user accordingly.

+
+Internet-Draft SPDY Feb 2012
+
+
+ stored at this index, it will be overwritten. The index is one
+ based, not zero based; zero is an invalid slot index.
+
+ Proof: Cryptographic proof that the client has possession of the
+ private key associated with the certificate. The format is a TLS
+ digitally-signed element
+ (http://tools.ietf.org/html/rfc5246#section-4.7). The signature
+ algorithm must be the same as that used in the CertificateVerify
+ message. However, since the MD5+SHA1 signature type used in TLS 1.0
+ connections can not be correctly encoded in a digitally-signed
+ element, SHA1 must be used when MD5+SHA1 was used in the SSL
+ connection. The signature is calculated over a 32 byte TLS extractor
+ value (http://tools.ietf.org/html/rfc5705) with a label of "EXPORTER
+ SPDY certificate proof" using the empty string as context. ForRSA
+ certificates the signature would be a PKCS#1 v1.5 signature. For
+ ECDSA, it would be an ECDSA-Sig-Value
+ (http://tools.ietf.org/html/rfc5480#appendix-A). For a 1024-bit RSA
+ key, the CREDENTIAL message would be ~500 bytes.
+
+ Certificate: The certificate chain, starting with the leaf
+ certificate. Each certificate must be encoded as a 32 bit length,
+ followed by a DER encoded certificate. The certificate must be of
+ the same type (RSA, ECDSA, etc) as the client certificate associated
+ with the SSL connection.
+
+ If the server receives a request for a resource with unacceptable
+ credential (either missing or invalid), it must reply with a
+ RST_STREAM frame with the status code INVALID_CREDENTIALS. Upon
+ receipt of a RST_STREAM frame with INVALID_CREDENTIALS, the client
+ should initiate a new stream directly to the requested origin and
+ resend the request. Note, SPDY does not allow the server to request
+ different client authentication for different resources in the same
+ origin.
+
+ If the server receives an invalid CREDENTIAL frame, it MUST respond
+ with a GOAWAY frame and shutdown the session.

+ named headers, send a header with two values, where the values are
+ separated by a single NUL (0) byte. A header value can either be
+ empty (e.g. the length is zero) or it can contain multiple, NUL-
+ separated values, each with length greater than zero. The value
+ never starts nor ends with a NUL character. Recipients of illegal
+ value fields MUST issue a stream error (Section 2.4.2) with the
+ status code PROTOCOL_ERROR for the stream-id.

+2.6.10.1. Compression
+
+ The Name/Value Header Block is a section of the SYN_STREAM,
+ SYN_REPLY, and HEADERS frames used to carry header meta-data. This
+ block is always compressed using zlib compression. Within this
+ specification, any reference to 'zlib' is referring to the ZLIB
+ Compressed Data Format Specification Version 3.3 as part of RFC1950.
+ [RFC1950]
+
+ For each HEADERS compression instance, the initial state is
+ initialized using the following dictionary [UDELCOMPRESSION]:
+
+ const unsigned char SPDY_dictionary_txt[] = {

+ The entire contents of the name/value header block is compressed
+ using zlib. There is a single zlib stream for all name value pairs
+ in one direction on a connection. SPDY uses a SYNC_FLUSH between
+ each compressed frame.
+
+ Implementation notes: the compression engine can be tuned to favor
+ speed or size. Optimizing for size increases memory use and CPU
+ consumption. Because header blocks are generally small, implementors
+ may want to reduce the window-size of the compression engine from the
+ default 15bits (a 32KB window) to more like 11bits (a 2KB window).
+ The exact setting is chosen by the compressor, the decompressor will

+
+3. HTTP Layering over SPDY
+
+ SPDY is intended to be as compatible as possible with current web-
+ based applications. This means that, from the perspective of the
+ server business logic or application API, the features of HTTP are
+ unchanged. To achieve this, all of the application request and
+ response header semantics are preserved, although the syntax of
+ conveying those semantics has changed. Thus, the rules from the
+ HTTP/1.1 specification in RFC2616 [RFC2616] apply with the changes in
+ the sections below.
+
+3.1. Connection Management
+
+ Clients SHOULD NOT open more than one SPDY session to a given origin
+ [RFC6454] concurrently.
+
+ Note that it is possible for one SPDY session to be finishing (e.g. a
+ GOAWAY message has been sent, but not all streams have finished),
+ while another SPDY session is starting.
+
+3.1.1. Use of GOAWAY
+
+ SPDY provides a GOAWAY message which can be used when closing a
+ connection from either the client or server. Without a server GOAWAY
+ message, HTTP has a race condition where the client sends a request
+ (a new SYN_STREAM) just as the server is closing the connection, and
+ the client cannot know if the server received the stream or not. By
+ using the last-stream-id in the GOAWAY, servers can indicate to the
+ client if a request was processed or not.
+
+ Note that some servers will choose to send the GOAWAY and immediately
+ terminate the connection without waiting for active streams to
+ finish. The client will be able to determine this because SPDY
+ streams are determinstically closed. This abrupt termination will
+ force the client to heuristically decide whether to retry the pending
+ requests. Clients always need to be capable of dealing with this
+ case because they must deal with accidental connection termination
+ cases, which are the same as the server never having sent a GOAWAY.
+
+ More sophisticated servers will use GOAWAY to implement a graceful
+ teardown. They will send the GOAWAY and provide some time for the
+ active streams to finish before terminating the connection.
+
+ If a SPDY client closes the connection, it should also send a GOAWAY
+ message. This allows the server to know if any server-push streams
+ were received by the client.
+
+ If the endpoint closing the connection has not received any
+
+
+
+Belshe & Peon Expires August 4, 2012 [Page 33]
+
+Internet-Draft SPDY Feb 2012
+
+
+ SYN_STREAMs from the remote, the GOAWAY will contain a last-stream-id
+ of 0.
+
+3.2. HTTP Request/Response
+
+3.2.1. Request
+
+ The client initiates a request by sending a SYN_STREAM frame. For
+ requests which do not contain a body, the SYN_STREAM frame MUST set
+ the FLAG_FIN, indicating that the client intends to send no further
+ data on this stream. For requests which do contain a body, the
+ SYN_STREAM will not contain the FLAG_FIN, and the body will follow
+ the SYN_STREAM in a series of DATA frames. The last DATA frame will
+ set the FLAG_FIN to indicate the end of the body.
+
+ The SYN_STREAM Name/Value section will contain all of the HTTP
+ headers which are associated with an HTTP request. The header block
+ in SPDY is mostly unchanged from today's HTTP header block, with the
+ following differences:
+
+ The first line of the request is unfolded into name/value pairs
+ like other HTTP headers and MUST be present:
+
+ ":method" - the HTTP method for this request (e.g. "GET",
+ "POST", "HEAD", etc)
+
+ ":path" - the url-path for this url with "/" prefixed. (See
+ RFC1738 [RFC1738]). For example, for
+ "http://www.google.com/search?q=dogs" the path would be
+ "/search?q=dogs".
+
+ ":version" - the HTTP version of this request (e.g.
+ "HTTP/1.1")
+
+ In addition, the following two name/value pairs must also be
+ present in every request:
+
+ ":host" - the hostport (See RFC1738 [RFC1738]) portion of the
+ URL for this request (e.g. "www.google.com:1234"). This header
+ is the same as the HTTP 'Host' header.
+
+ ":scheme" - the scheme portion of the URL for this request
+ (e.g. "https"))
+
+ Header names are all lowercase.
+
+ The Connection, Host, Keep-Alive, Proxy-Connection, and Transfer-
+ Encoding headers are not valid and MUST not be sent.
+
+
+
+Belshe & Peon Expires August 4, 2012 [Page 34]
+
+Internet-Draft SPDY Feb 2012
+
+
+ User-agents MUST support gzip compression. Regardless of the
+ Accept-Encoding sent by the user-agent, the server may always send
+ content encoded with gzip or deflate encoding.
+
+ If a server receives a request where the sum of the data frame
+ payload lengths does not equal the size of the Content-Length
+ header, the server MUST return a 400 (Bad Request) error.
+
+ POST-specific changes:
+
+ Although POSTs are inherently chunked, POST requests SHOULD
+ also be accompanied by a Content-Length header. There are two
+ reasons for this: First, it assists with upload progress meters
+ for an improved user experience. But second, we know from
+ early versions of SPDY that failure to send a content length
+ header is incompatible with many existing HTTP server
+ implementations. Existing user-agents do not omit the Content-
+ Length header, and server implementations have come to depend
+ upon this.
+
+ The user-agent is free to prioritize requests as it sees fit. If the
+ user-agent cannot make progress without receiving a resource, it
+ should attempt to raise the priority of that resource. Resources
+ such as images, SHOULD generally use the lowest priority.
+
+ If a client sends a SYN_STREAM without all of the method, host, path,
+ scheme, and version headers, the server MUST reply with a HTTP 400
+ Bad Request reply.
+
+3.2.2. Response
+
+ The server responds to a client request with a SYN_REPLY frame.
+ Symmetric to the client's upload stream, server will send data after
+ the SYN_REPLY frame via a series of DATA frames, and the last data
+ frame will contain the FLAG_FIN to indicate successful end-of-stream.
+ If a response (like a 202 or 204 response) contains no body, the
+ SYN_REPLY frame may contain the FLAG_FIN flag to indicate no further
+ data will be sent on the stream.
+
+ The response status line is unfolded into name/value pairs like
+ other HTTP headers and must be present:
+
+ ":status" - The HTTP response status code (e.g. "200" or "200
+ OK")
+
+ ":version" - The HTTP response version (e.g. "HTTP/1.1")
+
+
+
+
+
+Belshe & Peon Expires August 4, 2012 [Page 35]
+
+Internet-Draft SPDY Feb 2012
+
+
+ All header names must be lowercase.
+
+ The Connection, Keep-Alive, Proxy-Connection, and Transfer-
+ Encoding headers are not valid and MUST not be sent.
+
+ Responses MAY be accompanied by a Content-Length header for
+ advisory purposes. (e.g. for UI progress meters)
+
+ If a client receives a response where the sum of the data frame
+ payload lengths does not equal the size of the Content-Length
+ header, the client MUST ignore the content length header.
+
+ If a client receives a SYN_REPLY without a status or without a
+ version header, the client must reply with a RST_STREAM frame
+ indicating a PROTOCOL ERROR.
+
+3.2.3. Authentication
+
+ When a client sends a request to an origin server that requires
+ authentication, the server can reply with a "401 Unauthorized"
+ response, and include a WWW-Authenticate challenge header that
+ defines the authentication scheme to be used. The client then
+ retries the request with an Authorization header appropriate to the
+ specified authentication scheme.
+
+ There are four options for proxy authentication, Basic, Digest, NTLM
+ and Negotiate (SPNEGO). The first two options were defined in
+ RFC2617 [RFC2617], and are stateless. The second two options were
+ developed by Microsoft and specified in RFC4559 [RFC4559], and are
+ stateful; otherwise known as multi-round authentication, or
+ connection authentication.
+
+3.2.3.1. Stateless Authentication
+
+ Stateless Authentication over SPDY is identical to how it is
+ performed over HTTP. If multiple SPDY streams are concurrently sent
+ to a single server, each will authenticate independently, similar to
+ how two HTTP connections would independently authenticate to a proxy
+ server.
+
+3.2.3.2. Stateful Authentication
+
+ Unfortunately, the stateful authentication mechanisms were
+ implemented and defined in a such a way that directly violates
+ RFC2617 - they do not include a "realm" as part of the request. This
+ is problematic in SPDY because it makes it impossible for a client to
+ disambiguate two concurrent server authentication challenges.
+
+
+
+
+Belshe & Peon Expires August 4, 2012 [Page 36]
+
+Internet-Draft SPDY Feb 2012
+
+
+ To deal with this case, SPDY servers using Stateful Authentication
+ MUST implement one of two changes:
+
+ Servers can add a "realm=<desired realm>" header so that the two
+ authentication requests can be disambiguated and run concurrently.
+ Unfortunately, given how these mechanisms work, this is probably
+ not practical.
+
+ Upon sending the first stateful challenge response, the server
+ MUST buffer and defer all further frames which are not part of
+ completing the challenge until the challenge has completed.
+ Completing the authentication challenge may take multiple round
+ trips. Once the client receives a "401 Authenticate" response for
+ a stateful authentication type, it MUST stop sending new requests
+ to the server until the authentication has completed by receiving
+ a non-401 response on at least one stream.
+
+3.3. Server Push Transactions
+
+ SPDY enables a server to send multiple replies to a client for a
+ single request. The rationale for this feature is that sometimes a
+ server knows that it will need to send multiple resources in response
+ to a single request. Without server push features, the client must
+ first download the primary resource, then discover the secondary
+ resource(s), and request them. Pushing of resources avoids the
+ round-trip delay, but also creates a potential race where a server
+ can be pushing content which a user-agent is in the process of
+ requesting. The following mechanics attempt to prevent the race
+ condition while enabling the performance benefit.
+
+ Browsers receiving a pushed response MUST validate that the server is
+ authorized to push the URL using the browser same-origin [RFC6454]
+ policy. For example, a SPDY connection to www.foo.com is generally
+ not permitted to push a response for www.evil.com.
+
+ If the browser accepts a pushed response (e.g. it does not send a
+ RST_STREAM), the browser MUST attempt to cache the pushed response in
+ same way that it would cache any other response. This means
+ validating the response headers and inserting into the disk cache.
+
+ Because pushed responses have no request, they have no request
+ headers associated with them. At the framing layer, SPDY pushed
+ streams contain an "associated-stream-id" which indicates the
+ requested stream for which the pushed stream is related. The pushed
+ stream inherits all of the headers from the associated-stream-id with
+ the exception of ":host", ":scheme", and ":path", which are provided
+ as part of the pushed response stream headers. The browser MUST
+ store these inherited and implied request headers with the cached
+
+
+
+Belshe & Peon Expires August 4, 2012 [Page 37]
+
+Internet-Draft SPDY Feb 2012
+
+
+ resource.
+
+ Implementation note: With server push, it is theoretically possible
+ for servers to push unreasonable amounts of content or resources to
+ the user-agent. Browsers MUST implement throttles to protect against
+ unreasonable push attacks.
+
+3.3.1. Server implementation
+
+ When the server intends to push a resource to the user-agent, it
+ opens a new stream by sending a unidirectional SYN_STREAM. The
+ SYN_STREAM MUST include an Associated-To-Stream-ID, and MUST set the
+ FLAG_UNIDIRECTIONAL flag. The SYN_STREAM MUST include headers for
+ ":scheme", ":host", ":path", which represent the URL for the resource
+ being pushed. Subsequent headers may follow in HEADERS frames. The
+ purpose of the association is so that the user-agent can
+ differentiate which request induced the pushed stream; without it, if
+ the user-agent had two tabs open to the same page, each pushing
+ unique content under a fixed URL, the user-agent would not be able to
+ differentiate the requests.
+
+ The Associated-To-Stream-ID must be the ID of an existing, open
+ stream. The reason for this restriction is to have a clear endpoint
+ for pushed content. If the user-agent requested a resource on stream
+ 11, the server replies on stream 11. It can push any number of
+ additional streams to the client before sending a FLAG_FIN on stream
+ 11. However, once the originating stream is closed no further push
+ streams may be associated with it. The pushed streams do not need to
+ be closed (FIN set) before the originating stream is closed, they
+ only need to be created before the originating stream closes.
+
+ It is illegal for a server to push a resource with the Associated-To-
+ Stream-ID of 0.
+
+ To minimize race conditions with the client, the SYN_STREAM for the
+ pushed resources MUST be sent prior to sending any content which
+ could allow the client to discover the pushed resource and request
+ it.
+
+ The server MUST only push resources which would have been returned
+ from a GET request.
+
+ Note: If the server does not have all of the Name/Value Response
+ headers available at the time it issues the HEADERS frame for the
+ pushed resource, it may later use an additional HEADERS frame to
+ augment the name/value pairs to be associated with the pushed stream.
+ The subsequent HEADERS frame(s) must not contain a header for
+ ':host', ':scheme', or ':path' (e.g. the server can't change the
+
+
+
+Belshe & Peon Expires August 4, 2012 [Page 38]
+
+Internet-Draft SPDY Feb 2012
+
+
+ identity of the resource to be pushed). The HEADERS frame must not
+ contain duplicate headers with a previously sent HEADERS frame. The
+ server must send a HEADERS frame including the scheme/host/port
+ headers before sending any data frames on the stream.
+
+3.3.2. Client implementation
+
+ When fetching a resource the client has 3 possibilities:
+
+ the resource is not being pushed
+
+ the resource is being pushed, but the data has not yet arrived
+
+ the resource is being pushed, and the data has started to arrive
+
+ When a SYN_STREAM and HEADERS frame which contains an Associated-To-
+ Stream-ID is received, the client must not issue GET requests for the
+ resource in the pushed stream, and instead wait for the pushed stream
+ to arrive.
+
+ If a client receives a server push stream with stream-id 0, it MUST
+ issue a session error (Section 2.4.1) with the status code
+ PROTOCOL_ERROR.
+
+ When a client receives a SYN_STREAM from the server without a the
+ ':host', ':scheme', and ':path' headers in the Name/Value section, it
+ MUST reply with a RST_STREAM with error code HTTP_PROTOCOL_ERROR.
+
+ To cancel individual server push streams, the client can issue a
+ stream error (Section 2.4.2) with error code CANCEL. Upon receipt,
+ the server MUST stop sending on this stream immediately (this is an
+ Abrupt termination).
+
+ To cancel all server push streams related to a request, the client
+ may issue a stream error (Section 2.4.2) with error code CANCEL on
+ the associated-stream-id. By cancelling that stream, the server MUST
+ immediately stop sending frames for any streams with
+ in-association-to for the original stream.
+
+ If the server sends a HEADER frame containing duplicate headers with
+ a previous HEADERS frame for the same stream, the client must issue a
+ stream error (Section 2.4.2) with error code PROTOCOL ERROR.
+
+ If the server sends a HEADERS frame after sending a data frame for
+ the same stream, the client MAY ignore the HEADERS frame. Ignoring
+ the HEADERS frame after a data frame prevents handling of HTTP's
+ trailing headers
+ (http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.40).

+
+
+4. Design Rationale and Notes
+
+ Authors' notes: The notes in this section have no bearing on the SPDY
+ protocol as specified within this document, and none of these notes
+ should be considered authoritative about how the protocol works.
+ However, these notes may prove useful in future debates about how to
+ resolve protocol ambiguities or how to evolve the protocol going
+ forward. They may be removed before the final draft.
+
+4.1. Separation of Framing Layer and Application Layer
+
+ Readers may note that this specification sometimes blends the framing
+ layer (Section 2) with requirements of a specific application - HTTP
+ (Section 3). This is reflected in the request/response nature of the
+ streams, the definition of the HEADERS and compression contexts which
+ are very similar to HTTP, and other areas as well.
+
+ This blending is intentional - the primary goal of this protocol is
+ to create a low-latency protocol for use with HTTP. Isolating the
+ two layers is convenient for description of the protocol and how it
+ relates to existing HTTP implementations. However, the ability to
+ reuse the SPDY framing layer is a non goal.
+
+4.2. Error handling - Framing Layer
+
+ Error handling at the SPDY layer splits errors into two groups: Those
+ that affect an individual SPDY stream, and those that do not.
+
+ When an error is confined to a single stream, but general framing is
+ in tact, SPDY attempts to use the RST_STREAM as a mechanism to
+ invalidate the stream but move forward without aborting the
+ connection altogether.
+
+ For errors occuring outside of a single stream context, SPDY assumes
+ the entire session is hosed. In this case, the endpoint detecting
+ the error should initiate a connection close.
+
+4.3. One Connection Per Domain
+
+ SPDY attempts to use fewer connections than other protocols have
+ traditionally used. The rationale for this behavior is because it is
+ very difficult to provide a consistent level of service (e.g. TCP
+ slow-start), prioritization, or optimal compression when the client
+ is connecting to the server through multiple channels.
+
+ Through lab measurements, we have seen consistent latency benefits by
+ using fewer connections from the client. The overall number of
+ packets sent by SPDY can be as much as 40% less than HTTP. Handling
+
+
+
+Belshe & Peon Expires August 4, 2012 [Page 40]
+
+Internet-Draft SPDY Feb 2012
+
+
+ large numbers of concurrent connections on the server also does
+ become a scalability problem, and SPDY reduces this load.
+
+ The use of multiple connections is not without benefit, however.
+ Because SPDY multiplexes multiple, independent streams onto a single
+ stream, it creates a potential for head-of-line blocking problems at
+ the transport level. In tests so far, the negative effects of head-
+ of-line blocking (especially in the presence of packet loss) is
+ outweighed by the benefits of compression and prioritization.
+
+4.4. Fixed vs Variable Length Fields
+
+ SPDY favors use of fixed length 32bit fields in cases where smaller,
+ variable length encodings could have been used. To some, this seems
+ like a tragic waste of bandwidth. SPDY choses the simple encoding
+ for speed and simplicity.
+
+ The goal of SPDY is to reduce latency on the network. The overhead
+ of SPDY frames is generally quite low. Each data frame is only an 8
+ byte overhead for a 1452 byte payload (~0.6%). At the time of this
+ writing, bandwidth is already plentiful, and there is a strong trend
+ indicating that bandwidth will continue to increase. With an average
+ worldwide bandwidth of 1Mbps, and assuming that a variable length
+ encoding could reduce the overhead by 50%, the latency saved by using
+ a variable length encoding would be less than 100 nanoseconds. More
+ interesting are the effects when the larger encodings force a packet
+ boundary, in which case a round-trip could be induced. However, by
+ addressing other aspects of SPDY and TCP interactions, we believe
+ this is completely mitigated.
+
+4.5. Compression Context(s)
+
+ When isolating the compression contexts used for communicating with
+ multiple origins, we had a few choices to make. We could have
+ maintained a map (or list) of compression contexts usable for each
+ origin. The basic case is easy - each HEADERS frame would need to
+ identify the context to use for that frame. However, compression
+ contexts are not cheap, so the lifecycle of each context would need
+ to be bounded. For proxy servers, where we could churn through many
+ contexts, this would be a concern. We considered using a static set
+ of contexts, say 16 of them, which would bound the memory use. We
+ also considered dynamic contexts, which could be created on the fly,
+ and would need to be subsequently destroyed. All of these are
+ complicated, and ultimately we decided that such a mechanism creates
+ too many problems to solve.
+
+ Alternatively, we've chosen the simple approach, which is to simply
+ provide a flag for resetting the compression context. For the common
+
+
+
+Belshe & Peon Expires August 4, 2012 [Page 41]
+
+Internet-Draft SPDY Feb 2012
+
+
+ case (no proxy), this fine because most requests are to the same
+ origin and we never need to reset the context. For cases where we
+ are using two different origins over a single SPDY session, we simply
+ reset the compression state between each transition.
+
+4.6. Unidirectional streams
+
+ Many readers notice that unidirectional streams are both a bit
+ confusing in concept and also somewhat redundant. If the recipient
+ of a stream doesn't wish to send data on a stream, it could simply
+ send a SYN_REPLY with the FLAG_FIN bit set. The FLAG_UNIDIRECTIONAL
+ is, therefore, not necessary.
+
+ It is true that we don't need the UNIDIRECTIONAL markings. It is
+ added because it avoids the recipient of pushed streams from needing
+ to send a set of empty frames (e.g. the SYN_STREAM w/ FLAG_FIN) which
+ otherwise serve no purpose.
+
+4.7. Data Compression
+
+ Generic compression of data portion of the streams (as opposed to
+ compression of the headers) without knowing the content of the stream
+ is redundant. There is no value in compressing a stream which is
+ already compressed. Because of this, SPDY does allow data
+ compression to be optional. We included it because study of existing
+ websites shows that many sites are not using compression as they
+ should, and users suffer because of it. We wanted a mechanism where,
+ at the SPDY layer, site administrators could simply force compression
+ - it is better to compress twice than to not compress.
+
+ Overall, however, with this feature being optional and sometimes
+ redundant, it is unclear if it is useful at all. We will likely
+ remove it from the specification.
+
+4.8. Server Push
+
+ A subtle but important point is that server push streams must be
+ declared before the associated stream is closed. The reason for this
+ is so that proxies have a lifetime for which they can discard
+ information about previous streams. If a pushed stream could
+ associate itself with an already-closed stream, then endpoints would
+ not have a specific lifecycle for when they could disavow knowledge
+ of the streams which went before.

+
+5. Security Considerations
+
+5.1. Use of Same-origin constraints
+
+ This specification uses the same-origin policy [RFC6454] in all cases
+ where verification of content is required.
+
+5.2. HTTP Headers and SPDY Headers
+
+ At the application level, HTTP uses name/value pairs in its headers.
+ Because SPDY merges the existing HTTP headers with SPDY headers,
+ there is a possibility that some HTTP applications already use a
+ particular header name. To avoid any conflicts, all headers
+ introduced for layering HTTP over SPDY are prefixed with ":". ":" is
+ not a valid sequence in HTTP header naming, preventing any possible
+ conflict.
+
+5.3. Cross-Protocol Attacks
+
+ By utilizing TLS, we believe that SPDY introduces no new cross-
+ protocol attacks. TLS encrypts the contents of all transmission
+ (except the handshake itself), making it difficult for attackers to
+ control the data which could be used in a cross-protocol attack.
+
+5.4. Server Push Implicit Headers
+
+ Pushed resources do not have an associated request. In order for
+ existing HTTP cache control validations (such as the Vary header) to
+ work, however, all cached resources must have a set of request
+ headers. For this reason, browsers MUST be careful to inherit
+ request headers from the associated stream for the push. This
+ includes the 'Cookie' header.

+
+
+6. Privacy Considerations
+
+6.1. Long Lived Connections
+
+ SPDY aims to keep connections open longer between clients and servers
+ in order to reduce the latency when a user makes a request. The
+ maintenance of these connections over time could be used to expose
+ private information. For example, a user using a browser hours after
+ the previous user stopped using that browser may be able to learn
+ about what the previous user was doing. This is a problem with HTTP
+ in its current form as well, however the short lived connections make
+ it less of a risk.
+
+6.2. SETTINGS frame
+
+ The SPDY SETTINGS frame allows servers to store out-of-band
+ transmitted information about the communication between client and
+ server on the client. Although this is intended only to be used to
+ reduce latency, renegade servers could use it as a mechanism to store
+ identifying information about the client in future requests.
+
+ Clients implementing privacy modes, such as Google Chrome's
+ "incognito mode", may wish to disable client-persisted SETTINGS
+ storage.
+
+ Clients MUST clear persisted SETTINGS information when clearing the
+ cookies.
+
+ TODO: Put range maximums on each type of setting to limit
+ inappropriate uses.

+7. Incompatibilities with SPDY draft #2
+
+ Here is a list of the major changes between this draft and draft #2.
+
+ Addition of flow control
+
+ Increased 16 bit length fields in SYN_STREAM and SYN_REPLY to 32
+ bits.
+
+ Changed definition of compression for DATA frames
+
+ Updated compression dictionary
+
+ Fixed off-by-one on the compression dictionary for headers
+

+ instead of highest).
+
+ Fixed bug: Name/Value header counts were duplicated in both the
+ Name Value header block and also the containing frame.

+ General usage is simple: include this header, declare or define two
+ functions with zero parameters (void) and any return type: one for
+ initialization and one for deinitialization, add
+ _SET_INIT_AND_DEINIT_FUNCS(FuncInitName, FuncDeInitName) to the code
+ and functions will be automatically called during application startup
+ and shutdown.
+ This is useful for libraries as libraries doesn't have direct access
+ to main() functions.
+ Example:
+ -------------------------------------------------
+ #include <stdlib.h>
+ #include "autoinit_funcs.h"
+
+ int someVar;
+ void* somePtr;
+
+ void libInit(void)
+ {
+ someVar = 3;
+ somePtr = malloc(100);
+ }
+
+ void libDeinit(void)
+ {
+ free(somePtr);
+ }
+
+ _SET_INIT_AND_DEINIT_FUNCS(libInit,libDeinit);
+ -------------------------------------------------
+
+ If initializer or deinitializer functions is not needed, just define
+ it as empty function.
+
+ This header should work with GCC, clang, MSVC (2010 or later).
+ Supported C and C++ languages; application, static and dynamic (DLL)
+ libraries; non-optimized (Debug) and optimized (Release) compilation
+ and linking.

+ * All symbols defined in this header start with MHD. MHD is a small
+ * HTTP daemon library. As such, it does not have any API for logging
+ * errors (you can only enable or disable logging to stderr). Also,
+ * it may not support all of the HTTP features directly, where
+ * applicable, portions of HTTP may have to be handled by clients of
+ * the library.
+ *
+ * The library is supposed to handle everything that it must handle
+ * (because the API would not allow clients to do this), such as basic
+ * connection management; however, detailed interpretations of headers
+ * -- such as range requests -- and HTTP methods are left to clients.
+ * The library does understand HEAD and will only send the headers of
+ * the response and not the body, even if the client supplied a body.
+ * The library also understands headers that control connection
+ * management (specifically, "Connection: close" and "Expect: 100
+ * continue" are understood and handled automatically).
+ *
+ * MHD understands POST data and is able to decode certain formats
+ * (at the moment only "application/x-www-form-urlencoded" and
+ * "mulitpart/formdata"). Unsupported encodings and large POST
+ * submissions may require the application to manually process
+ * the stream, which is provided to the main application (and thus can be
+ * processed, just not conveniently by MHD).
+ *
+ * The header file defines various constants used by the HTTP protocol.
+ * This does not mean that MHD actually interprets all of these
+ * values. The provided constants are exported as a convenience
+ * for users of the library. MHD does not verify that transmitted
+ * HTTP headers are part of the standard specification; users of the
+ * library are free to define their own extensions of the HTTP
+ * standard and use those with MHD.
+ *
+ * All functions are guaranteed to be completely reentrant and
+ * thread-safe (with the exception of #MHD_set_connection_value,
+ * which must only be used in a particular context).
+ *
+ * NEW: Before including "microhttpd.h" you should add the necessary
+ * includes to define the `uint64_t`, `size_t`, `fd_set`, `socklen_t`
+ * and `struct sockaddr` data types (which headers are needed may
+ * depend on your platform; for possible suggestions consult
+ * "platform.h" in the MHD distribution). If you have done so, you
+ * should also have a line with "#define MHD_PLATFORM_H" which will
+ * prevent this header from trying (and, depending on your platform,
+ * failing) to include the right headers.
+ *
+ * @defgroup event event-loop control
+ * MHD API to start and stop the HTTP server and manage the event loop.
+ * @defgroup response generation of responses
+ * MHD API used to generate responses.
+ * @defgroup request handling of requests
+ * MHD API used to access information about requests.
+ * @defgroup authentication HTTP authentication
+ * MHD API related to basic and digest HTTP authentication.
+ * @defgroup logging logging
+ * MHD API to mange logging and error handling
+ * @defgroup specialized misc. specialized functions
+ * This group includes functions that do not fit into any particular

+ * @brief public interface to libmicrospdy
+ * @author Andrey Uzunov
+ * @author Christian Grothoff
+ *
+ * All symbols defined in this header start with SPDY_. libmisrospdy is a small
+ * SPDY daemon library. The application can start multiple daemons
+ * and they are independent.<p>
+ *
+ * The header file defines various constants used by the SPDY and the HTTP protocol.
+ * This does not mean that the lib actually interprets all of these
+ * values. Not everything is implemented. The provided constants are exported as a convenience
+ * for users of the library. The lib does not verify that provided
+ * HTTP headers and if their values conform to the SPDY protocol,
+ * it only checks if the required headers for the SPDY requests and
+ * responses are provided.<p>
+ *
+ * The library uses just a single thread.<p>
+ *
+ * Before including "microspdy.h" you should add the necessary
+ * includes to define the types used in this file (which headers are needed may
+ * depend on your platform; for possible suggestions consult
+ * "platform.h" in the libmicrospdy distribution).<p>
+ *
+ * All of the functions returning SPDY_YES/SPDY_NO return
+ * SPDY_INPUT_ERROR when any of the parameters are invalid, e.g.
+ * required parameter is NULL.<p>
+ *
+ * The library does not check if anything at the application layer --
+ * requests and responses -- is correct. For example, it
+ * is up to the user to check if a client is sending HTTP body but the
+ * method is GET.<p>
+ *
+ * The SPDY flow control is just partially implemented: the receiving
+ * window is updated, and the client is notified, to prevent a client
+ * from stop sending POST body data, for example.

+ * @file proxy.c
+ * @brief Translates incoming SPDY requests to http server on localhost.
+ * Uses libcurl.
+ * No error handling for curl requests.
+ * TODO:
+ * - test all options!
+ * - don't abort on lack of memory
+ * - Correct recapitalizetion of header names before giving the headers
+ * to curl.
+ * - curl does not close sockets when connection is closed and no
+ * new sockets are opened (they stay in CLOSE_WAIT)
+ * - add '/' when a user requests http://example.com . Now this is a bad
+ * request
+ * - curl returns 0 or 1 ms for timeout even when nothing will be done;
+ * thus the loop uses CPU for nothing

+Testcases in this directory require zzuf and socat.
+
+zzuf is used to randomly mess with the TCP connection between the CURL
+clients and the MHD server. The goal is to expose problems in MHD's
+error handling (by introducing random syntax errors). socat is
+used to listen on port 11081 and forward the randomzied stream to
+port 11080 where MHD is waiting.
+
+As a result, the testcases in this directory do NOT check that
+whatever CURL returns is what was expected -- random modifications to
+the TCP stream can have random effects ;-). Testcases "fail" if the
+code crashes or hangs indefinitely.
