Magento

Id like to know how i could add a default route for all products, such ass

(the sku part is obviously replaced by a sku here).

If the product exists it goes straight to the product details page, if not, it goes to an error page.

I read about the zend framework routing, i found the classes and everything, but i have not figured out how to add this route yet.  Maybe someone already did that.

I need it to be automatic for all products, so using the “url rewriting management” is pretty much out of the question, unless i didnt see some option.. I have far too many products to do them all one by one.

Thanks a lot!
