Re: [Libevent-users] Crash in my simple multi-threaded evhttp app [code incl.]

[Julian Bui <julianbui@xxxxxxxxx>]

For anyone following this thread and interested in what I ended up doing: I found POCO which has a nice networking library that uses the select mechanism and has a multi-thread HTTP server library.  It seems to be working well so far.

Thanks for replying, Nick.

I probably cannot use libevhtp because it appears to be too small of a project to get company approval for my application.  We worry about support and maintenance issues.

Does anyone have any other suggestions for an embedded http server/library that has multi-threaded support?  

I've been programming with libevent for a few weeks now and have really liked the interfaces and capabilities which makes it frustrating to hear that I won't be able to use the http capabilities because of its threading limitations.

I'm pretty sure that evhttp is not safe for use from multiple threads
at once.  If you need an HTTP server library suitable for
multithreaded use, I'd strongly suggest you take a look at Mark's
libevhtp; it appears to be much better than evhttp.
