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

hi,
i am not sure if squid is required to not cache sites without suitable
headers.
does anybody know?
it seems as if for such objects the refresh-patterns are NOT used in
squid.conf.
is this right?

thx in advance,
alp
