RE: Preserve cache - remember to increase refresh patterns

Hi Charles (cool surname!) & squid-users

There's a slight change to your procedure that would make things run a bit
smoother...

3A - Set the refresh pattern(s) in Squid v1 squid.conf file REALLY HIGH so
that all objects are apparently fresh. Otherwise Squid-1 will do all sorts
of IMS requests. The alternative to this is to create a smart list of URLs
that are fresh based upon the entries in squid-1's store.log and squid.conf.

Agreed.
rm -rf cache & made me cringe :)
