There is two solutions to this problem.

a) Use another load balancing algorithm which keeps the session on the
same forwarding path. Hmm.. for some reason we don't have that.. thought
we had a destinationhash method.. Someone should do that based on

b) Use NAT on the outgoing traffic from the caches to nat them all to a
single externaly visible address

srchash may work, but you should then make sure to disable caching
entirely at the first Squid. Also hit ratio will not be the best...
