Thanks. It makes sense since setting "always direct" to this acl evaluates the acl once (and also once on the always direct rule, but this is expected).
The four acl evaluations return success, so is it possible to configure squid to stop at the first success or just evaluate one algorithm? E No. peer acls is evaluated during peering selection, not during re-forwarding. More likely it's because the peer was selected by 4 different algorithms. It's an accelerator where going direct is not allowed so Squid tries really hard to find all possible paths to forward the request. Regards Henrik
