External redirects

Hi,
I would like to have an external redirect to my payment provider.
So I tried using:

PHP Code:

$this->response->setHeader('Location', $payment->getCheckoutUrl()); 


This doesn't work. Just a blank page is given. No error message.
I am in developer mode, so I would expect some kind of error, or a succesfull redirect.
Als a simple PHP header('Location: URL') has the same result.

I have checked the checkout URL and it's fine.

SOLVED:
return redirect()->to($molliePayment->getCheckoutUrl());

Please add [SOLVED] to your post title on the end.
