[squid-users] squid refresh_pattern / cache question

[Berkes, David]

I have a question about the caching mechanism and "refresh_pattern" specifically.  I had the following configured for my company.  Lateley there have been complaints that people are seeing old pages and not the recent content...specifically when going to www.bbc.com<http://www.bbc.com>.

Im not actually sure what is not allowing the bbc.com pages to not get updated, but at this point, I just want to let squid do normal caching without any refresh_pattern or "fancy" settings.

My question is will I still get caching features/benefits of squid after I remove the "refresh_pattern" entries?

Thank you.
