As I wrote in another post I've got problem with my version of squid. It seems like it doesn't want to cache anything until I set up refresh_pattern with very high values, something like: refresh_pattern . 35000000 100% 35000000 I don't know if it's my fault, I mean, maybe there's something wrong in my squid.conf (I've even tried to post it here, but I got no response...) Anyway, I don't really understand that well how squid decide what is fresh (thus it can keep it in cache) or stale (therefore something to purge). Reading squid.conf.default I can read: Basically a cached object is: # # FRESH if expires < now, else STALE # STALE if age > max # FRESH if lm-factor < percent, else STALE # FRESH if age < min # else STALE Here comes the question: how can any object be considered fresh when its expiry time is < than actual time?!?!? If it's already expired how can it be fresh!?!? Moreover what is exactly age?!? Is it the time since last modification, I mean age = now - last-modified!?!?! And, what is lm-factor!? Thanks all!
