RE: [squid-users] question concerning php-sites and caching -still some questions

some sites dont want their pages to cached, so i guess squid will eventually
reload pages.

-still some questions

thanks marc,

i knowed this page already, it's a really nice one.
but my problem is: does squid never caches an object without validation
headers (expires, max-age, lastmod,...)?
if i have a refresh-pattern like
refresh_pattern . 0 20% 5
such an object should retain at most 5 minutes in cache, shouldn't it?
or is refresh_pattern only used if an object has validation headers?

thx in advance,
alp
