I would like to be able to generate detailed reports of a internet access habits.

For example, i would like to be able generate a report  to know at a glance how much time 192.168.x.x spends on facebook each day/month/

I would also like the option to tell the proxy to report instead of block those sites.

For example.
I have facebook denied.
When a user goes to facebook, I don't the site to be blocked, but instead just report how much time was spend on that site each day.. or any site in the denied access configuration.

I  would then be able to make the decision to block the site based on how much time the user is spending at the site.
