Yes, this is possible. In thread-per-connection mode, you can just block in the callback. If you use an event loop, you must call MHD_suspend_connection(), and then MHD_resume_connection() once you are ready to serve the reply. > > 2)I know libmicrohttpd is a server.

Nope, but there are libraries like libwget2 and libcurl for that. git.taler.net/twister contains an example for implementing a proxy combining MHD and libgnurl. Best regards, Christian
