 | When an HTTP proxy is used --proxy, this option will make curl tunnel through | 
 | the proxy. The tunnel approach is made with the HTTP proxy CONNECT request and | 
 | requires that the proxy allows direct connect to the remote port number curl | 
 | wants to tunnel through to. | 
 |  | 
 | To suppress proxy CONNECT response headers when curl is set to output headers | 
 | use --suppress-connect-headers. |
