Web Proxy/Monitoring Software?

[ssharkey at linuxunlimited.com (Scott Sharkey)]

Hi All,

I have a need for a service or software that will monitor and track 
outbound HTTP (web) accesses, and report what pages are being visited.
I know that Squid theoretically can do this, but it seems like overkill 
for this application.  The user could care less about caching - they 
just want to monitor what URL's their staff is visiting.

IS squid the best option, or is there something else that would do a 
better job?  Part of my concern is that the machine they have to run 
this on does not have a huge amount of memory, and I understand Squid 
can be a memory hog.

Thanks!!!
