You don't -have- to do that - it'd be mostly trivial to write a basic TCP tunnel in Squid -just- for intercepting arbitrary TCP ports to do basic ACLs (eg source/dest IP; throw request into a CONNECT to an upstream proxy, etc) - but noone's written it for Squid-2. The big question is - why do you want to intercept port 443?

The only problem is that we cant figure out how to get HTTPS requests redirected from the ASA to the proxy (using WCCP). Does anyone know how this can happen? Do I need to use dynamic's instead of standards for WCCP?
