Re: [squid-users] My cache is far away from full. But lots of things get released. Why?

Squid basically caches anything that either can be considered fresh for
at least one minute or which can be revalidated.

Squid does not cache
a) Objects which is explicitly marked as uncacheable by the origin
server

b) Objects which is expired (or very soon to expire), and which cannot
be revalidated.
