Hiya, Just a heads-up; Henrik fixed the issue with Linux servers being unable to join a service group with more than one router defined. I've verified that the latest squid-2.6 snapshot will happily join a service group with a pair of Cisco routers (7204 running 12.3(16) and 2651 running 12.4(2)T1.) I'm also in the process of improving our WCCPv2 support in various ways thanks to a handful of people (The Measurement Factory and iiNet, among others) who have donated/loaned me enough equipment to have a small interception caching lab here. I'm in the process of comparing the Squid-2.6 WCCPv2 implementation against one of the later CE590/ACNS caches to see what we could do "better". Let us know if it works or doesn't work for you.
