Hello Dear Sir : We tested external_acl_type for web authentication via writing check.php , and login feature is fine squid config is external_acl_type session ipv4 concurrency=10 ttl=3600 negative_ttl=0 cache=1048576 %SRC /opt/check.php check.php ( for login) is fwrite(STDOUT, $source_ip." OK\n"); But if we don't squid -k reconfigure , logout feature is bad for me how to update Ok or ERR cache entry without squid -k reconfigure check.php ( for logout ) is fwrite(STDOUT, $source_ip." ERR\n"); if possible , please give me some advisement _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
