How to do URL Transformations?
I understand how to use the Ultimate SEO URLs like
http://www.zen-cart.com/index.php?ma...roducts_id=231
But I want to erase those "C" "P" and IDs, Like P-22,C-12.
For example:
I want this url
http://www.modem3g.com/e5830-router-p-39.html
to be
http://www.modem3g.com/e5830-router.html
Anyone can help me?
Tks in Adance.

You would have to roll your own....

There is really no need to do any of this as the SE's can handle the normal url's just fine
