If it is not set, Synapse +will log a warning on each received request. + +To avoid the warning, administrators using a reverse proxy should ensure that +the reverse proxy sets `X-Forwarded-Proto` header to `https` or `http` to +indicate the protocol used by the client. See the [reverse proxy +documentation](docs/reverse_proxy.md), where the example configurations have +been updated to show how to set this header. + +(Users of `Caddy <https://caddyserver.com/>`_ are unaffected, since we believe it +sets `X-Forwarded-Proto` by default.) + Upgrading to v1.27.0 ==================== |
