Hi , i've got a question about a external_acl. We use an own external helper to check if a user is in a particular group and then assign a special outgoing ip address. Here is an example: external_acl_type HELPER ttl=3600 negative_ttl=300 children=10 concurrency=0 cache=0 grace=0 protocol=2.5 %SRC /path/to/helper acl group1 external HELPER group1 acl group2 external HELPER group2 http_access allow group1 tcp_outgoing_address 1.2.3.4 group1 http_access allow group2 tcp_outgoing_address 1.2.3.5 group2 In the helper protocol I notice that squid try to reauthenticate User that belongs to group2 every 10 minutes in group1, even when they already allowed in group2. Is there an option that squid tell to remember successful authentications? Kind regards Marc
