Hm, FTP will be a bit nasty - I'm not sure how WCCP will redirect all
the traffic for the dynamic data ports..

Good question! I'll take a look when I get home tonight.

I think so. I'll re-read the spec (and the code) tonight.

I don't think squid has the smarts to do this; but its easy to emulate.
You'd just redirect multiple traffic ports in iptables (one per rule) to
Squid, and have a bunch of http_port lines, eg:

http_port 3128 ip.ip.ip.ip:3128 transparent vport=80
http_port 8080 ip.ip.ip.ip:8080 transparent vport=8080
http_port 8081 ip.ip.ip.ip:8080 transparent vport=8081

.. which I think -should- work, but its a good question! I'll try it out
with my WCCPv2 testing setup at home and let you know.
