Redirect Friendly Store URL to different page

[Robert4049]

How could I go about redirecting  index.php?rp=/store/web-hosting to somewhere else? 
The product group ID I'm attempting to apply this is 2 but this winds up applying to all store URLs.

 

<?php
add_hook("ClientAreaPage",1,function($vars){
   if ($vars['filename']=="index" && !isset($_REQUEST['2'])){
       header("Location: ../");
       exit;
   }
});
