    # https://httpd.apache.org/docs/2.4/mod/mod_proxy.html#x-headers
    # mod_proxy_http already adds these headers by default:
    # X-Forwarded-For:    The IP address of the client.
    # X-Forwarded-Host:   The original host requested by the client in the Host HTTP request header.
    # X-Forwarded-Server: The hostname of the proxy server. 
    # there is also another option:
    # https://httpd.apache.org/docs/2.4/mod/mod_proxy.html#proxypreservehost
    # ProxyPreserveHost: When enabled, this option will pass the Host: line from the incoming request to the proxied host, instead of the hostname specified in the ProxyPass line.
    # if the backend supports it, X-Forwarded-Host is the cleaner solution
    # we almost always want to inform the backend of the protocol though, which isn't sent by default
    RequestHeader set X-Forwarded-Proto "https"
