[GLLUG] Web proxy with tracking/login?

[Mike Szumlinski]

I figured I would ask here since there is a lot of OSS use.  Does  
anyone have any recommendations for a web proxy that allows for login  
based tracking?  I have a customer looking to track where their  
employees have been during the day, but since it is such a small shop  
a lot of the appliance based commercial proxies are overkill on both  
price and features.

Anyone know of anything out there or can make any recommendations?
