Seem so. I have just tested 12.3(19), 12.4(8) and 12.4(6)T - same problem on
all versions. I am assuming this is a platform independent thing - I'm using
low end routers to test.

What is interesting is that WCCPv1 works just fine with the same code.

I do, but I've not the expertise to know about WCCP to take on the TAC. That's
a possible avenue to take this but it won't fix the immediate problem.

RFC compliance then becomes nothing more than marketing hype if the vendor isn't
interested in actually maintaining and fixing bugs that increase RFC compliance
or fix bugs relating to this.

Yes, I agree entirely. But to have any hope of not having the workaround, it
needs to be fixed properly going forward.

I should dust off the old CE500 cache engine I have here (it's now obsoleted by
much more modern gear, it's sitting in the spare room taking up space) but it
will do WCCPv2 I think...might be interesting to see what it sends over the wire
compared to what squid-2.6 does.

You may wish to view and add comments to
http://www.squid-cache.org/bugs/show_bug.cgi?id=1584 where this WCCPv2 problem
is being tracked.
