Squid caches the sites. The algorithm used is documented in the
config file. Basically you can say for example that pages are cached
for 20% of their age subject to a maximum time of 2 weeks.

This is correct for version 1.0. I think version 1.1 uses a different
system where it sends if-modified-since requests so this should stop
this happening. I am not sure though.

If version 1.1 sends if-modified-since requests then the web server
should count these.

Purging of expired sites happens on a continual basis. It also will
have a good purge if the cache becomes within a certain percentage of
it's maximum specified size.

It would be worth you looking through the squid.conf file.
