proxy server for reporting internet usage by various users

[vishal shah]

Do you know about a proxy server which has innovative way of reporting internet usage by various users?*

[EINSTEIN_007]

The thing is that the proxy server solution will enable the users to determine who the usage belongs to, rather than just where it was done (eg by PC name). Of course, this does depend on what it is and what you had before, but typically some kind of user authentication will be used (quite possibly transparent to the user). This improves non-repudiation ("it wasn't me, I left my machine on when I went out to lunch") and enables clever rules ("let some people have this content but not you").
