 * This function is called before a outgoing request is made.

 * - context.outgoingRequestRedirects is set: Inside the context of this incoming request, there was a redirect
 * - The hostname of the URL contains a private IP address
 * - The redirect origin, so the user-supplied hostname and port that caused the first redirect, is found in the context of the incoming request
