Here's my issue. I have an installation of a popular shopping cart. That cart generates the products in the format of /product.php pages w/ the specific product ID attached. (i.e. www.mysite.com/product.php?ID234)
I have rewritten the cart extensively because the client needed a very highly customized shopping process. Now, the customer is directed to a new page, /product1.php which servers up the proper options for checking out.
However, Google is still indexing the cart and all of the products with the /product.php extention.
I am wondering if its possible to write a redirect that, if clicked from an external referrer, redirects any product.php page to the exact same page, exept as product1.php.
If so, is it is possible to leave the INTERNAL workings of the cart unaffected? That is, some pages DO start with product.php and should be left along. It's just the ones coming from google search that I need to redirect.
Is this possibe?
