| <h2>Specification</h2> | |
| For requests which have information attached after the header, such as | |
| HTTP POST or PUT, the information will be sent to the script on stdin. | |
| <p> | |
| The server will send <a href="http://hoohoo.ncsa.uiuc.edu/cgi/env.html#cl">CONTENT_LENGTH</a> bytes on | |
| this file descriptor. Remember that it will give the <a href="http://hoohoo.ncsa.uiuc.edu/cgi/env.html#ct">CONTENT_TYPE</a> of the data as well. The server is | |
| in no way obligated to send end-of-file after the script reads | |
| <code>CONTENT_LENGTH</code> bytes. </p><p> | |
| </p><hr> | |
| <h2>Example</h2> | |
| Let's take a form with METHOD="POST" as an example. Let's say the form | |
| results are 7 bytes encoded, and look like <code>a=b&b=c</code>. | |
| <p> | |
| In this case, the server will set CONTENT_LENGTH to 7 and CONTENT_TYPE | |
| to application/x-www-form-urlencoded. The first byte on the script's | |
| standard input will be "a", followed by the rest of the encoded string.</p><p> | |
