I've been racking my brain without success (writer's block combined with inexperience?).
I need to append a slash (only) if there isn't already a 3-4 letter extension. I'm using IIS7's url rewrite module.
http://mydomain.com/mypage becomes http://mydomain.com/mypage/
While http://mydomain.com/mypage1.aspx or http://mydomain.com/mypage/ are left alone.
Anyone have any pointers?
