Regular expressions for url redirect matching, but no redirect happens

Hi guys, im having trouble with some regular expressions and url tracker. The expression matches the url but no redirect takes place.

my expression:

(.*)\/portfolio\/(.*)

Im hoping to match any url that has /portfolio/ in it, ive tested this against several hundred urls using http://regexr.com/ but when putting this into url tracker, expecting a redirect nothing takes place.

Anyone have any ideas?
