Hi, I am trying to use a configuration like this: external_acl_type squid_unix_group children=15 %LOGIN /usr/local/squid/libexec/squid_unix_group acl users_abuseband external squid_unix_group abuseband delay_access 2 allow users_abuseband delay_access 2 allow otheracl delay_access 2 allow moreacl delay_access 2 deny all Squid does not complain when -k reconfigure. I tried to stop the squid process too, but, it doesn't work. I mean, the access made by an user in abuseband group is still not getting delay_pool 2 but delay_pool 8, where, because another ACL (src) it should be. I read the message http://www.squid-cache.org/mail-archive/squid-users/200310/0905.html, that talks about rep_mime_type and delay_pools not working, so, I would like to know if an external acl like squid_unix_group works with delay_pools. I have tested an external squid_unix_group directive with http_access and it worked. I mean, I created a group named 'blocked' and inserted an user in the group. Then, I made an acl, just like the one I described before and used it in a http_access deny directive and it worked. The users in group 'blocked' were blocked. Have I missed something? Could someone, please, help me? Forgive me about my bad english. Thank you for your attention. Regards, Freitas
