HAProxy IP Forward Support

It would be nice if you could get the IP forwarding work with HAProxy and this! ❤️ 

Some idea can probably be gotten from https://github.com/PanSzelescik/proxy-protocol-support/blob/forge/src/main/java/pl/panszelescik/proxy_protocol_support/

It may be a bit unrelated about this project, but worth a shot :)

Thanks-
