I think all pieces of the WCCP2 issue has now fallen into place, except
the questionmarks in the message referenced above. Awaiting testing of
the proposed patch before commit.

From what it looks the equipment he uses simply not compatible with
Squid at the moment as it seems it only supports mask based assignment,
and we only support hash based assignment.

Regarding the mask based assignments. I wonder how complex mask arrays a
typical equipment supports. In the specs is an unbounded array only
limited by the UDP packet size.

The mask specifications can build very powerful expressions, but also
harder to distribute among the farm members.
