Symfony2 Twig url() https

Question

I need to generate an absolute URL that will use the secure HTTP protocol since it's a payment page template used by a third party payment gateway solution that requires every single element on the page to point to or to come from an HTTPS link. Now, I can't for the life of me find how to use the Twig url() function to generate a secure URL. Anything you add to the function in an array is considered a GET parameter that will be appended at the end of the URL in a ?x=y manner.

How can I generate an HTTPS URL using the Twig url() function???

Thanks in advance.

The URLs generated by twig are determined by your routing configuration. You need to set the route to require https.

requirements:
    _scheme:  https
