Using the contains function

and making that ‘this url contains’ and the portion you want recognized ‘cd-players’ in your example you can then redirect the user to the main page you want them to view.

But this won’t help with the idea of duplicate content on pages as both pages would still exist in your app, however with more thought and proper set up you could avoid ever having the duplicate page and always navigate the user to the one page Amazon.com. Spend less. Smile more. that you want them to view regardless of where in the app they are or how they might be searching.
