I solved this using MHD_USE_THREAD_PER_CONNECTION, and locks to block threads. I wrapped this code up on GitHub at [1] (look at microhttpd_pubsub.h). It's probably not ideal if you are going to have lots of clients connecting to one server, but this worked for my small-scale needs. As an aside, I haven't actually published a link to this before, so if you (or anyone else) ends up looking at it, I'd be happy to respond to any questions/comments. It's been a little while since I looked at this code though. -Tom Wambold [1]: https://github.com/tom5760/microhttpd_utils
