hijacking \CodeIgniter\Controller

I found this script from Killishan's blog and your pdf. 

Code:

class Home extends \CodeIgniter\Controller
{
public function __construct(...$params)
{
parent::__construct(...$params);
// This controller is only accessible via HTTPS
if (! $this->request->isSecure())
{
// Redirect the user to this page via HTTPS, and set the Strict-
Transport-Security
// header so the browser will automatically convert all links to this
page to HTTPS
// for the next year.
force_https();
}
}
