It means that the only CARP thing Squid can (currently) do is the
routing, combined with caching if you like.

                    /-- "CARP" parent 1
                   /
clients -> squid ------ "CARP" parent 2
                   \
                    \-- "CARP" parent 3

Why I put CARP withing quites above is because Squid does not implement
a full CARP client, only the hashing algorithm of CARP. Squid does not
know how to retreive or parse the CARP array membership table. Squid
also does not know how to route requests within a single CARP array.
