Proxy-Authenticate
The HTTP Proxy-Authenticate response header defines the
authentication method that should be used to gain access to a resource behind a
proxy server. It authenticates the request to the proxy server, allowing
it to transmit the request further.
The Proxy-Authenticate header is sent along with a 407
Proxy Authentication Required.
