It does not do what you wrote unfortunately. Haproxy can load patterns from a file upon startup and append them to the other patterns declared on the same line. So basically "-f /etc/haproxy/maintenance.mode on" will match all patterns from maintenance.mode and "on" against whetever you use the ACL with. At the moment there is no way to fetch constant data to compare to patterns, though that can easily be done on 1.5. I think I can add some fetches to do that as well as for using environment variables. However you need to keep in mind that matching against patterns from files only happens once when you reload the config, so I'm not certain this is what you need. Willy
