And that's why I was considering Squid. It seems that for transparent proxying, you need Squid to be compiled with certain switches. I have yet to find a LEAF Squid compiled in this way, and I don't have a LEAF compile environment.
I'm not quite sure what you mean here.
Squid can be set up in no-cache mode quite easily via the squid.conf file ... see
http://www.squid-cache.org/Doc/FAQ/FAQ-4.html#ss4.20
for the details.
If you want Squid to cache invisibly ... that it, redirect all port-80 and port-443 traffic to it without the knowledge of the end user ... that is a bit trickier (and it is a major problem for any URLs that involve non-standard ports). TheSquid FAQ at
http://www.squid-cache.org/Doc/FAQ/FAQ-17.html
seems to say that, for a Linux system, the necessary reconfiguration can be done in squid.conf (and some iptables rules, of course).
But in all of this, I may still be misunderstanding what you want to accomplish ... in particular, how thoroughly you want to conceal the existence of this monitoring scheme from your customers. (If you don't want to conceal it at all, just run Squid as a normal proxy and tell them they have to set their browsers to use it. Right?)
I'd suggest that to get better help, you need to describe in a bit more detail what you actually want to accomplish.
