Python websocket chat server with Apache?

Question

What is the best way to make a browser=based chat server with a python back-end?

For the reverse-AJAX type of pushing, I found autobahn and Twisted, but is there a good way to push information from one client to all other clients?

The tutorials for Twisted and Autobahn all seemed to indicate a 1-1 connection between a single python instance and a single client.

Follow-up question: Is there a way to configure apache to allow clients to connect to a web socket that is on port 80, if apache is already on port 80? So something like ws:domain/foo.py, insted of having to specify a different port.

You can't share a port between multiple apps, though you CAN use a dispatcher to handle incoming requests and hand off data as needed to whatever app should be receiving it. however, apache isn't set up for this. — Marc B

Thanks, that was my suspicion. Do you know of any python method/library where I can onMessage from anyone sendMessage to everyone? — cyrusv

Autobahn doesn't use "reverse-AJAX" (whatever that's supposed to be ;), but WebSockets.

You can easily broadcast messages sent by clients to all connected clients using a couple of lines:

This is pure WebSockets.

You can also do much more sophisticated stuff, general Publish & Subscribe with Autobahn using WAMP (WebSockets Application Messaging Protocol) over WebSockets which Autobahn also provides.

Please see the other tutorials on our site .
