I need professional help here... Here's the situation... I have product URL's going to detail pages. On that page it breaks out into sub-sections, at times it also carries extra parameters in the query string other than "v" and "fa"... note that "v" is an alpha-numeric...

I think this is because of the "_" in your regular expression. You may need to change your pattern to look like this: "^testing/([_0-9a-z]+)" The pattern as you have it right now will match only "testing/_anything"
