|  | --- | 
|  | Send a HAProxy PROXY protocol v1 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. |
