Greetings, I feel I am missing something simple. I have installed squid3 on Ubuntu. I added acl allow_domains dstdomain "/etc/squid3/always_direct.acl" always_direct allow allow_domains acl denied_domains dstdomain "/etc/squid3/denied_domains.acl" http_access deny denied_domains and populated both files accordingly, and restarted squid3. Now from a terminal, curl good-url and it works. curl bad-url and it gives me the blocked message. Try it in firefox, and good-url and bad-url both work fine. Neither is blocked. What did I forget? Thanks. Paul
