Try to use cachemgr.cgi if you use squid of course.

if you have access to the proxy logs you can analyze them by using a tool like webalizer, that generates html-output with graphics and all stuff.

you just have to tell squid to use common log file format, that can be done by editing the squid.conf file.

This problem arised couple of times at couple of places we've a squid installation.
The answer is quite surprising - it's very hard.
The reasons are:
1) The log file is updated only *after* the transfer is completed, e.g. if your client downloads ISO image - 650MB, then you'll see it only after he finishes.
2) The user-ip mapping is non trivial.
However, these problems could be solved:
1) use cachemgr interface, for example:
cache_object://localhost/info
will show the "info" screen which you can see with cachemgr.cgi
So, you don't use logs at all, you see the current TCP connections and URLs
netstat won't give you url, just ips.
2) use user authentification, so every user must authentificate before he surfs. Otherwise, create a db for fast lookups.
Now, put it all together and write a perl script.
This is an answer.

ah.. the cache_object://localhost/info
must be asked from proxyhost:proxyport
it could be other host rather then localhost, and then, authentification or special permissions (squid.conf) - acl, is needed.
