RegEx ... a comprehensive list?

Giga_Dave — Sat, 09 Mar 2013 19:15:16 GMT

I've looked through the documentation and cannot seem to find a "begins with" regex variable. The common symbol ^ seems to be reserved in PA for match any except. Is there a solution or is this not available?

Depends on what you are trying to set in the regex, but starting with a .* could help you

I've looked through the Admin Guide (5.0 and 6.0) and have found no clarification as to what FLAVOR of regex are supported. I.e. are they the full POSIX standard regex? or are they some subset thereof? Do we have to escape all special characters? So many questions, so few answers. :smileycry:

Its Perl based regex. But you need to first have seven static bytes, ie characters, before you can set your regex match pattern. This is to prevent overloading the firewall by giving it the seven characters to match first before doing the regex.
