描述
HAProxy defines a TCP-based "proxy protocol" that wraps / prefixes reverse-proxy traffic with metadata from the original client.
See http://www.haproxy.org/download/1.8/doc/proxy-protocol.txt.

Akka HTTP lacks proxy protocol support. There already was a demand in spray/spray#846. It's impossible to implement anti-flood scenarios in case of plain tcp connections when there is no way to determine real client ip via HTTP headers passed from reverse proxy.
