Re: [squid-users] no-cache , no-store

Hi amos

Thanks for your reply.

By turning setting session.cache_limiter off in php.ini would i be
able to cache these php generated pages??
Do you think my squid.conf is correct to cache the pages?? i only get
a lot of TCP MISS in my access.log :(

This is my squid.conf:
------------------------------------------------------------------------------------------------------------
