According to this thred it can be done. If you take a look at the second last post you'll see that the user claims he made it work using this piece of code.
if(isset($_SERVER['QUERY_STRING'])) {
$_GET['path'] = "/" . ereg_replace("404;" . 'DI_HOST_NAME' . "/", "", $_SERVER['QUERY_STRING']
);
if(substr($_GET['path'], strlen($_GET['path'])-1) == "/")
$_GET['path'] = substr($_GET['path'],0,strlen($_GET['path'])-1);
}
My problem is that I havn't got any ide how to make it work.
