refresh_pattern . 0 20% 4320
refresh_pattern -i \.exe$ 99999 20% 99999 reload-into-ims
refresh_pattern \.ram$ 999999 20% 99999 override-expire ignore-reload
refresh_pattern ^http: 999999 20% 99999

i want using .ram extension i want to cache it and enforce squid if end user do refresh to keep user take from cache what is the option? i use override-expire ignore-reload but didn't work! moreover, i always got in logs like :
1248715635.319 1090 192.168.0.25 TCP_REFRESH_UNMODIFIED/304 657 GET http://pagead2.googlesyndication.com/pagead/sma7.js - DIRECT/74.125.113.164 text/javascript

what does TCP_REFRESH_UNMODIFIE ?
i want TCP_Refresh from end user to ingore and enforce him to keep take from cache
Thanks alot for your help =)

for your ".ram" extensions, don't you need to add a "ignore-no-cache" and "ignore-no-store" options to counter directives from the webserver not to cache .ram files?

Also, you are ignoring reload requests but what about the "refresh-ims" option to convert users "refresh" requests into if-modified-since requests?

TCP_REFRESH_UNMODIFIED = The requested object was cached but STALE. The IMS query for the object resulted in "304 not modified".

Also, unless I am mistaken, these refresh_pattern rules are read in order, like a firewall table. So your "catchall" rule should be last.

hey
thanks alot i got it so always refresh_pattern . 0 20% 4320 at last
about ignore-no-cache and ignore-no-store( this use for like ^http: ^ftp: ? for hyper text transfer protocol ?
and about this : refresh-ims and refresh-into-ims (must be together right?)
another thing for extensions like \.exe$ \.ram$ (what best option to use for them to keep the network in best performance ) ?
also can i set on refresh_pattern if i want to cache a specific site contain pics can i use like refresh_pattern ^http://www.saidacity.net? for example
thanks again for your help really =)
