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-Schemeheader was added 10 years ago, whyX-Schemewas used back then and notX-Forwarded-Proto, nobody knows today / possibly becauseX-Forwarded-Protowasn't a de-facto standard back then.[1] https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/X-Forwarded-Proto
