I changed that but same problem, 404 not found error.

routes.php
$route['default_controller'] = "Contr_redirect";

Contr_redirect.php
<?php

class Contr_redirect extends CI_Controller{
function index()
{
redirect('catalog/index.php', 'location');
}
}

?>

http://localhost
404 Page Not Found

The page you requested was not found.

On a completely separate note, should I be doing this anyway?
AM I supposed to place the OSCommerce app into the applictaion folder entirely?

Any ideas?
