If the original server does not want to accept trust by sending a request, it should return 401 (unauthorized)Echo. The response must include a WWW-Authentication Header. Second, the response must contain at least one (possibly new) requested resource.(Challenge). If the proxy does not accept the request to send trust, it should return a 407 (proxy authentication required) response.The response must include a proxy_authenticate header domain, which mu
