$the_host = $_SERVER['HTTP_HOST'];
 $request_uri = isset($_SERVER['REQUEST_URI']) ? $_SERVER['REQUEST_URI'] : '';
 if($the_host !== 'www.jb51.net')
 {
         //echo $_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'];
        header('HTTP/1.1 301 Moved Permanently');
        header('Location: //www.jb51.net' . $_SERVER['PHP_SELF']  . $request_uri);
