A minimal http server and client pair. It's intended to show how to communicate between a server and a client in Python.

server-http.py

#!/usr/bin/env python
"""
Very simple HTTP server and client pair in python. 
Server based on: https://gist.github.com/bradmontgomery/2219997
Usage::
    ./server-http.py start [<port>]

Send a message (on a second terminal) ::
    ./server-http.py notify "hello world!"

Stop the server (on a second terminal) ::
    ./server-http.py stop

Cool, do you have a version for Python 3?

@MxShift I have some Python3 code in two repos that may have related code

https://github.com/ericoporto/hotreload
https://github.com/ericoporto/fgmk/blob/master/fgmk/game_server.py

I may need to update the above code if it's being found in Google or something.
