question about basics of creating a PROXY to MONITOR network activity

[cseb...@gmail.com]

I'm trying to create an application that stands in between all
connections to a remote server to monitor behavior for
security and compliance reasons.

I'm guessing I'll have all users log into this middle man proxy
application instead of logging into the original website?

Are there any frameworks or existing Python apps to help 
with this project?

Thanks,

Chris
