So it looks like WCCP with an ASA (or some other Cisco WCCP2 supporting device) and Squid (v3?) can only do port 80 interception huh....blah

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? (Ive tried, without success).

Squid-2 doesn't support any form of HTTPS "interception".

I could probably be twisted to implement a basic tunnel just for supporting
intercepted requests (so you can do very basic ACL processing on them.)
