Still no luck. Well, something is terribly wrong with the testing. Because the rep_mime_type and http_reply_access you have above are the correct way to do it. Are you judging it by requests going back? or the result reaching client? To block the reply, Squid MUST first ask for it and receive back at minimum the reply headers. The client never sees what is given to Squid though. > > Here's my latest ACL in my config (not working) > # Basic ACLs > acl manager proto cache_object > acl localhost src 127.0.0.1/32 > acl to_localhost dst 127.0.0.0/8 > acl mydomain dstdomain .domain.com .static.com localhost > acl localnet src 10.0.0.0/16 > acl Safe_ports port 80 # http > acl purge method PURGE > acl CONNECT method CONNECT > http_access allow manager localhost > http_access deny manager > http_access allow purge localhost > http_access deny purge > http_access deny !Safe_ports > http_access allow mydomain first-listed first-match.
