replies with set-cookie headers are not cached in v1.1. For v1.2
they will be cached, but without the set-cookie header.

not cached.

There are a number of HTTP request and reply headers used to
determine if a cached page is stale or fresh.

For a basic overview, see "Refresh Rules and If-Modified-Since" in
http://squid.nlanr.net/Squid/1.1/Release-Notes-1.1.txt.
