hey need help with this
i try to use
acl 6arab url_regex http://www.saidacity.net
no_cache allow 6arab
and try
refresh_pattern ^http://www.saidacity.net 0 80% 99999 ignore-no-cache ignore-no-store

it sometimes give me TCP_HIT and sometimes TCP_MISS
i try different browser
not only this site , different site

and when it give me TCP_HIT , when i open the site, it's some how slow!!

one more thing, if i cache file.exe for example and i change the min age which is 0 to 9999 , and restart squid, does the object expire? since when i change the min age all objects .exe are expired

Thanks for your help and hope can someone help me thx alot

What are your trying to achieve??
what are the defaults? and have you commented them out? what the order of the refresh_pattern line? show me your complete squid.conf

Please note: by default, regular expressions are CASE-SENSITIVE. To make them case-insensitive, use the -i option.

From Squid documentation:
So you were forewarned!

Thanks alot =)

there you go! your confs are just splattered around. Put all your acls together, then your http_access lines together. It will be a good i dea to follow headlines like global configs, acl configs, cache_perfomance tuning, logging etc. and group your configs accordinmg to this.
You will note that squid.conf obeys ORDER, so the order in which your configs are layed out matters, and have greater impact on the behaviour of your proxy server. For example, your own refresh_pattern configs should come first before the defaults. You have not commented on ignore-no-store and imho, you dont need to use it.
you config file is not sane, so you cant expect advanced settings to work when basic settings are not done properly. I think you would do better by understanding squid structure first before attempting to fiddle with cache settings. trial and error will only leave you frustrated.
