I was surprised to find out that there is no implementation for WebSockets support in Apache web server.
But there is a way to make it work.
pywebsocket project is an Apache "extension" written in python, so mod_python is required also, and with it Apache can support HTML5 WebSockets. it is very easy to install and configure.
I flowed the instructions in this URL: http://www.travisglines.com/web-coding/how-to-set-up-apache-to-serve-html5-websocket-applications-with-pywebsocket
