Host: * X-Forwarded-Host/X-Forwarded-Port headers * Host field on the request (parsed from Host header) * Host in the request's URL (parsed from Request-Line)

Scheme: * X-Forwarded-Proto header * Existence of TLS information on the request implies https * Scheme in the request's URL (parsed from Request-Line) * Port (if included in calculated Host value, 443 implies https) * Otherwise, defaults to "http"
