Yes. I have had the case that the outside interface is nonfunctioning, but squid is still up and accepts clients on the inside interface. Squid then becomes a black hole for client traffic, so I would prefer a terminating squid in that case. > No clients get stuck at the nonfunctioning squid in a cache-hierarcy.

So that feature is built-in already (if I > am not misunderstanding your scenario). No cache-hierarchy, just several redundant squid servers on the same level. Roundrobin is handled by internal DNS, which has multiple A-records for the hostname "proxy". Peter Olsson
