PHP or HTACCESS Redirect

Hello- this should be pretty easy, I'm just not a PHP expert. I built a new site, but the browsers and other websites link to my product pages using a query string link with old filenames. I need to redirect the queries to use the new filenames. How would I create this redirect? Example ---------- Old Site: [login to view URL] New Site: [login to view URL] I tried using .htaccess for redirection, but could not get it to work. I tried this: Options +FollowSymlinks RewriteEngine On RewriteRule ^[login to view URL]$ ../[login to view URL] [L] Thanks, Robert
