Hi,
Once you have the DSEFU mod installed, can customers still use the old format links?
Example
The default old link used to be:
www.store.com/product.php?productid=123
With the DSEFU SEO installed the same link is now:
www.store.com/product-name-pr-123.html
Now... Can a customer still use the old-format link (product.php?productid=123) to access the same page? Also, if they can, are there any negative SEO effects to this?
