You can't make an arbitrary nginx module to talk via WebSocket
protocol, this isn't going to work.

What you can is to use nginx to proxy WebSocket connections to
some WebSocket backend server using proxy_pass, as documented
here:

http://nginx.org/en/docs/http/websocket.html

Note that you need an actual backend server handling WebSocket
connections for proxying to work.
