HTTPS 체크 

if($_SERVER['HTTPS'] != "on") {
      refresh("https://".$_SERVER['HTTP_HOST'].":8002".$_SERVER['REQUEST_URI']);
      exit;
} 

 

또는..

 

$protocol = stripos($_SERVER['SERVER_PROTOCOL'],'https') === true ? 'https://' : 'http://';
$url = $protocol.$_SERVER["HTTP_HOST"].'/files/editer/';
