The page with the login form is always https, of course. I was
ignoring the URL of that in my examples because it's irrelevant. It
doesn't have to be even on the same domain using the kind of
authentication scheme that Google does. The page you *started at*, the
one that redirected you to the login page, is the one that determines
where you go after logging in.

HTTPS is just transport level security (unless you're using client
certificates, which you're not). Authentication of this kind is at the
application level and the transport you're using (http vs. https)
doesn't change anything. It's usually some expiring token, stored in a
cookie, that you can verify on every request.
