This is a regular expression issue. $ matches the end of the input, so if you leave it off (as in the second example), everything that starts with (the ^ matches the beginning of the input) polls/ would match. As you can see, that's true of everything that would match the second pattern, so nothing will ever get to the second pattern because it will match the first one. This site http://www.regular-expressions.info/ has an extensive tutorial of regexes. (Note also that the r in front of the expression string means that the string is a raw expression. Otherwise you'd have to type \\ every time you meant \.)
