The HTTP X-Forwarded-Proto (XFP) request header is a *de-facto* standard header
for identifying the protocol (HTTP or HTTPS) that a client used to connect to a
proxy or load balancer.[1]
The ``X-Scheme`` header was added 10 years ago, why ``X-Scheme`` was used back
then and not ``X-Forwarded-Proto``, nobody knows today / possibly because
``X-Forwarded-Proto`` wasn't a *de-facto* standard back then.

have still been retained.
