Hi, I'm using zeromq between a request and a response. Its socket is not thread-safe and that's one of the reasons I chose MHD_USE_SELECT_INTERNALLY. As I am also using a thread pool, I have different sockets for each thread. It is expensive to open and close a socket in every connection and I would like to share a socket between all same-thread connections. I didn't find a way to do it, so I made a small change in the code <https://github.com/cemsbr/libmicrohttpd/commit/3151eff47553a8a93db7fb3355366b31aed2b262> in order to get the thread number (starting from 0) from the connection daemon. Thus, I can initialize an array of sockets only once (in the main function) and have them indexed by the thread number to be accessed later.
As a side effect, I have to include internal.h, but it is working as expected. Was there a better way of doing this that I haven't noticed? Regards, Carlos Eduardo
