+ * @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.
