Why do I have one page showing as two url's?

[BradBorst]

My SEOMoz stats show that I have duplicate titles for the following two url's:

http://www.rmtracking.com/products.php and http://www.rmtracking.com/products

I have checked my server files, and I don't see a live page without the php.  A while back, we converted our site from html to php, but the html pages have 301's and as you can see the page without the php is properly redirecting to the php page.  Any ideas why this would show as two separate url's?

First link is your standard .php page

Second link is a duplicate of page 1 http://www.rmtracking.com/products/index.php

In other words it sees http://www.rmtracking.com/products/index.php as http://www.rmtracking.com/products/ which is a duplicate

I am inclined to think you must be linking to it somewhere if it is showing up in a crawl. Export your crawl to a csv and search for it and check the referring page.

I think you were right.  I did what you said and found it linked from a flash file.  Since this is the only one showing in the csv crawl report, I think it's fixed.  Thanks very much for your help!
