.php instead of .html

I have an existing ecommerce site with a different software and am converting to CS Cart. All product URLs are formed like this:


However, unlike CS Cart, it doesn’t use mod_rewrite to form the urls–I had to create static pages for everything.

So, I’d like to know if there is a way to have CS Cart rewrite the urls with a .php ending instead of .html. That way, I won’t have to put two hundred 301 redirects in my .htaccess file pointing to the new pages. Also, hopefully this would cut down on any temporary loss of ranking due to what the search engines will consider new pages.

Thanks in advance for any help.
