Previously require-secure would cause a redirect loop if run on an app server behind an SSL-terminating reverse proxy, like an Amazon ELB. That's because it ignored X-FORWARDED-PROTO and other headers and just checked whether keter was being talked to over an encrypted socket. This change uses WAI's "was this request made over a secure connection?" logic as a supplement to the old way.
