So, I did this in routes:
$route['default_controller'] = "Contr_redirect";

I made a controller called Contr_redirect with:
<?php

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

?>

However, I get a 404 error when going to http://localhost
