 * An HTTPS request is going through a proxy that requires NTLM authentication, and the default credentials do not have access. The HTTP request is going through the same proxy again.
 * An HTTPS request is going through a proxy that requires NTLM authentication, the default credentials do have access, the initial HTTP 407 response from the proxy contains data content (Content-Length is not 0), and the initial HTTP 407 response does not contain a &quot;Proxy-Connection: Close&quot; header. The HTTP request is going through the same proxy again.
