You need to apply your acls with some deny statements. http_reply_access deny blockfiles for your mp3's, etc. To block websites I use dstdomain instead of url_regex. So my squid.conf contains: acl blocksites dstdomain "/etc/squid/squid-block.acl" http_access deny blocksites One other suggestion would be to block by filetype and not just file extension. Thomas J.
