Squid wont' give an "access denied" in case of a 404. Squid will cache 404 replies for a while if required. The fact that squid is returning an Access Denied means something about the request didn't match an allow ACL or matched a deny ACL. You should try to understand why Squid is returning an "Access denied" error here.
