XF 2.0 User sessions external site

[GameXperience]

Hi !

I use Xen for a while now on some of my communities , and i'm looking for upgrading to Xen 2.0

Actually, one of my community used a custom xenforo php bridge like this :

(find this script before on community forums, can't find it now)

        $startTime = microtime(true);
        $fileDir = '/{somepath}/xenforo';

        require($fileDir . '/library/XenForo/Autoloader.php');
       
       
        XenForo_Autoloader::getInstance()->setupAutoloader($fileDir . '/library');

        XenForo_Application::initialize($fileDir . '/library', $fileDir);
        XenForo_Application::set('page_start_time', $startTime);
        XenForo_Session::startPublicSession();

        public function getVisitor() {
            return XenForo_Visitor::getInstance();
        }

        $user = $this->getVisitor();

In Xen2.0, is something better to get sessions on the external part of my community ?
