RedirectScheme

Redirecting the Client to a Different Scheme/Port

The RedirectScheme middleware redirects the request if the request scheme is different from the configured scheme.

When behind another reverse-proxy

When there is at least one other reverse-proxy between the client and Traefik, the other reverse-proxy (i.e. the last hop) needs to be a trusted one.

Otherwise, Traefik would clean up the X-Forwarded headers coming from this last hop, and as the RedirectScheme middleware relies on them to determine the scheme used, it would not function as intended.
