[squid-users] refresh_pattern question

Hi,

>From squid.conf,
refresh_pattern . 21600 100% 21600 override-expire

That is, a cached page is fresh if its age in cache < 15 days
(21600=15*24*60).

I noticed that sending HTTP requests to pages older than 30 days result
in TCP_REFRESH_MISS while requests for pages cached in the last 30 days
either result in TCP_HIT or TCP_MISS. Since the min time for
refresh_pattern is 15days, shouldn't it be like pages older than 15days
should be validated against the parent (REFRESH_MISS/REFRESH_HIT) while
all other pages are either TCP_HIT or TCP_MISS. How did the limit change
from 15 to 30? Has anybody else seen such an anamoly?

Also, if there's no refresh_pattern matching a URI, how would Squid
process that HTTP request? Would it get a fresh copy from the parent or
will it return the cached copy?

Thanks.
