APM :: Detecting IE 11
Ok I suck, I know. But why is this wrong? expr { [string tolower [mcget {session.user.agent}]] matches_regex {trident\/7.+rv\:11} } It never matches... even though my UA is: Mozilla/5.0 (Windows NT 10.0; Win64; x64; Trident/7.0; rv:11.0) like Gecko I'm using an empty branch rule with this as the 'advanced' script above. Always hits fallback (i.e. doesn't match).
