Force 404 without 302

[sferrerowebimpacto]

Hello, I've modified the Dispatcher.php class so, when the url is modified and it doens't match the real product url it will redirect you to the 404 page, this is they code I've used to redirect it:

Tools::redirect('index.php?controller=404');

I get redirected to my 404 page, but the problem is that, along with the 404 (red arrow), a 302 from the redirect is send (yellow arrow).

I've also tried using:

Controller::getController('PageNotFoundController')->run();

 

But I receive this screen instead of my 404 website:

 

Is there a way of forcing the 404 without the 302?

 

Thanks.

In case anyone has this problem in the future what I ended up doing was putting this code inside de init function of ProductController when it meets my condition:

header('HTTP/1.1 404 Not Found');
header('Status: 404 Not Found');
$this->setTemplate('errors/404');
