HTTP Header Support

In addition, to injecting the Forwarded and X-Real-Ip headers the X-Forwarded-For, X-Forwarded-Port and X-Forwarded-Proto headers are added to HTTP(S) and Websocket requests. Custom headers for the ip address and protocol can be configured with the proxy.header.clientip, proxy.header.tls and proxy.header.tls.value options.

Since version 1.5.3 fabio also sets the X-Forwarded-Host header.
