How do I redirect pages to another page?

I know how to redirect a single page to a single page. However, I have about 500 pages that my index.php file has created. Pages like index.php=cpath=57, index.php=cpath=127, and so on. Is their a way that I could put a redirect on index.php and have all those sublinks be redirect to the same page, too?

I have installed a new shopping system and I do not want people purchasing from our old shop. Our old shop is indexed in many engines.

THanks!

 

i dont know exactly but i think it can be done by htaccess
