On the official website (<http://www.squid-cache.org/>) menu under "Documentation" we have several sources: * Reference guide - for detailed description of a specific directive if you are needing reminder of usage or specific details of its operation. * Examples - how-to config snippets for common installation needs. * Books for learning Squid; beginners guide, and expert reference. * FAQ and Wiki for more up to date alternative to the books. > > That is something it should be written clear in the documentation. > Maybe it is somewhere, but I could not find that information. > <https://wiki.squid-cache.org/SquidFaq/SquidAcl#And.2FOr_logic> > > Same for http_access.. how does it works?

Deny as much as possible first, allow later. Faster ACL types first whenever possible.
