The version itself is probably most of the prooblem. 3.1 does not cache traffic with Cache-Control:no-cache, which these days consists of a large percentage (30-40) of all traffic. That is resolved in 3.2 and later, along with better caching of private and authenticated traffic. You can find details of newer CentOS RPM packages from Eliezer at http://wiki.squid-cache.org/KnowledgeBase/CentOS Amos
