What you have there is the IP cache. These are not the same TTLs
for the cached Web pages.

I don't know which version you're running. If its 1.0.x, then you
should probably upgrade to 1.1.x. For a description of how Squid 1.1.x
deals with fresh/stale objects, see the v1.1 Release Notes section
"Refresh Rules and If-Modified-Since"
