Hello, On the webpage http://wiki.squid-cache.org/faq/authentication in the section Authentication in accelerator mode Authentication is by default disabled in acceleartor mode in Squid-2.X due to conflicts with transparent interception. To enable this feature, at the top of acl.c add the following line: Unfortunately that is where it ends. I am running 2.5.STABLE11 redhat rpm is accelerator authentication supported in this version by default? Thanks, Jerry -- Jerry Thomas thomasj@xxxxxxxxxxxxxx I.T.
