How to know many computers connect to the Internet through Proxy PC !

[trinhlk]

In one LAN, have many PCs connect to internet through Proxy PC. Each PC can open some websites.
How to check that PC is accessing which websites by one programming language.

If you can, give me source code for example.
Thanks!

Doesn't the proxy server have aduit logs? Maybe the web proxy even has a programming interface, so you can plug-in your own modules (like a URL logging module).

You can always write your own web or SOCKS proxy, but it seems a bit overkill when you already have a proxy in your LAN.
