Even if you can trust the referer, it's only going to tell you that the previous request used https, not the current one.

Isn't it easier to configure the HTTP server to only accept https connections?

REMOTE_ADDR can be faked, but is harder to do. But that doesn't give you any information whether the request was using https or not.

As a general advice, don't roll your own security. Leave it to the experts, and do it at the right layer.
