If you're running a squid transparent proxy yes the administrators can monitor what sites are being visited and even restrict them.

I think the answer to your question is not so much what is current in squid as what you can add on to squid to make it do what you want. Please take a look at sarg and squidguard for examples of utilities that add on functionality that you may be interested in (I'm sure that there are others; eg, calamaris...and for some things, a simple bash script may suffice, bt you might find it easier to work with a package which has the capabilities that you want).

What? I am not able to assign any worthwhile meaning to that, so let's hope that it is unimportant.

If you have squid installed, just set in squid.conf

Code:

http_port 3128 transparent

.

Also you will need to forward all the http traffic to squid port. It normally is 3128, unless you change it.

Code:

iptables -t nat -A PREROUTING -i $LAN_INTERFACE -p tcp --dport 80 -j REDIRECT --to-port 3128

This should make your squid work in transparent mode without your need to configure browsers. But in this way you loose control of the web access and it is always better to keep your squid not working transparently.
