Long: haproxy-protocol
Help: Send HAProxy PROXY protocol header
Protocols: HTTP
Added: 7.60.0
---
Send a HAProxy PROXY protocol header at the beginning of the connection. This
is used by some load balancers and reverse proxies to indicate the client's
true IP address and port.

This option is primarily useful when sending test requests to a service that
expects this header.
