RE: [squid-users] how to use refresh_pattern correct

Thanks Dan,
I get about 40% cache rate with no real issues with websites. And my web
surfing performance is sub-3 second response times in most cases.

Best regards,

Hi Lawrence

I think that's the most extensive list of refresh patterns I've seen in one
place, for a forward proxy. Props.

Is anyone else using a collection like this and care to comment on its
performance / viability?
