Hello Amos, Thank you for your answer! I do not use expire header, my problem is that I only have Cache-Control max-age headers on my dynamic pages (no Last-Modified) and I really need to cache this pages according to the max-age headers. what will be the best way to do it? Set header on apache to the system time environment variable, can it be done? Or is there a way to overcome this issue with the squid configuration, and force the caching even though it have no Last-Modified headers? is that other way without changing my application? I tried the following configuring on squid but nothing work for me. refresh_pattern JHTML 60 75% 360 ignore-reload ignore-no-cache ignore-no-store override-lastmod override-expire acl JHTML urlpath_regex .*\.jhtml no_cache deny JHTML cache allow JHTML #Ignore force reload to send reqest to the server refresh_pattern . 0 100% 86400 ignore-reload refresh_pattern (\.jhtml|\.html) 0 75% 350 ignore-reload ignore-no-store override-lastmod thanks again Maoz On Mon, 2009-01-26 at 13:53 +1300, Amos Jeffries wrote: > Expires
