/**
* @file demo_https.c
* @brief complex demonstration site: create directory index, offer
* upload via form and HTTP POST, download with mime type detection
* and error reporting (403, etc.) --- and all of this with
* high-performance settings (large buffers, thread pool).
* If you want to benchmark MHD, this code should be used to
* run tests against. Note that the number of threads may need
* to be adjusted depending on the number of available cores.
* Logic is identical to demo.c, just adds HTTPS support.
