X-Cart:Redirect Loop Error

If your server is behind a proxy and generates the error "Firefox has detected that the server is redirecting the request for this address in a way that will never complete" or something else related to a redirect loop error, try adding this code to your top.inc.php file:

if( isset( $_SERVER["HTTP_X_FORWARDED_HOST"]))
$_SERVER["HTTP_HOST"] = $_SERVER["HTTP_X_FORWARDED_HOST"];
