I'm using URL rewriting to make my url http://example.com/foo/bar/ to http://example.com/index.php/foo/bar. I'm not linking the index.php/.. url anywhere, but for some reasons, some users arrives to the index.php url. In Google analytics, I have a lot of duplicates that are quite annoying to follow up the traffic. I've watched the Advanced filters but I'm struggling to make it works fine. Any regex and google analytics pro to help me out ?
