SSL cake PHP form - ssl

Question

I spent the site in https, I have 2 questions, the site is redirected but is it a 301 redirect? I did not write anything in the .htaccess file, how come the site is redirected in https?
I'm afraid of dupicate content.
The problem I have is that emails do not work anymore ...
here is the code:
public function initialize()
{
parent::initialize();
$this->loadComponent('Security', ['blackHoleCallback' => 'forceSSL']);
$this->loadComponent('RequestHandler');
$this->loadComponent('Flash');
$this->loadComponent('Auth', [
'authenticate' => [
'Form' => [
'fields' => [
'username' => 'email',
'password' => 'password'
],
'finder' => 'auth'
]
],
'loginAction' => ['controller' => 'Users', 'action' => 'login', 'prefix' => 'manager'],
'loginRedirect' => ['controller' => 'Pages', 'action' => 'index', 'prefix' => 'manager'],
'logoutRedirect' => ['controller' => 'Users', 'action' => 'login', 'prefix' => 'manager'],
// 'authorize' => 'Controller'
]);
}
public function forceSSL()
{
return $this->redirect('https://' . env('SERVER_NAME') . $this->request->here);
}
public function beforeFilter(Event $event)
{
parent::beforeFilter($event);
$this->Security->requireSecure();
$this->checkManager();
$this->set('settings', Configure::read('Settings'));
}
Thank you

Answer 1

here is the solution:
public function initialize()
{
parent::initialize();
$this->loadComponent('Security', ['blackHoleCallback' => 'forceSSL']);
}
public function forceSSL()
{
return $this->redirect('https://' . env('SERVER_NAME') . $this->request->here);
}
public function beforeFilter(Event $event)
{
parent::beforeFilter($event);
$this->Security->requireSecure();
$this->Security->config('unlockedActions', ['contact']);
}
AND :
Change statut in Controller.php
public function redirect($url, $status = 302)
Becomes :
public function redirect($url, $status = 301)
