Hallo, this is my first posting, so "hi @ all". System is a SuSE8.1 with squid-2.4.STABLE7-288. I don' t want pdf-Documents to be cached, so i put ### acl pdf urlpath_regex .pdf$ no_cache deny pdf ### in squid.conf. As that didn' t work, i used ### acl Morning time 08:00-11:00 no_cache deny Morning ### for testing-purposes, which is copied from the Squid-FAQ (http://www.squid-cache.org/Doc/FAQ/FAQ-7.html#ss7.8). But still i get "TCP_HIT"' s in the access.log. Any hints would be appreciated. Have a nice day.. Sören Anderson
