Websocket backend

What are the best options for websocket backends? I’m working with an
embedded platform so I’m somewhat restricted to something lightweight
in C/C++. The things I found so far are:

libwebsockets: http://git.warmcat.com/cgi-bin/cgit/libwebsockets/
poco: http://www.appinf.com/docs/poco/Poco.Net.WebSocket.html

Another option would be to handle it right in Openresty/ngx_lua. I
see there was some discussion about this a little while back:

What are the best options?

I haven’t tried it yet, but nginx-push-stream-module looks good:


I agree with him too.

This looked interesting but I ran into two issues. I need to be able to
filter publishes on a connection basis. Also, the GPLv3 license is not
suitable for my project.
