User access time limit

[Sean Ali <sean.ali@xxxxxxxxx>]

Hello,

I'm quite new to squid but I have managed to set it up along with 
squidGuard just fine. However, right now for space management purposes 
in the lab, I would like to restrict the user's access to just 1 hour 
of time. Once that time is up they would have to see the system admin 
to have more time granted. Is this possible with squid? Does anyone 
know how I might accomplish this?

Thanks,
Sean.
