+*  **followRedirects**: specify whether you want to follow redirects. Possible values:
+   * `false` (default): do not follow redirects
+   * `true`: follow redirects and use default options
+   * Object: specify options for following redirects.

 *  **selfHandleResponse** true/false, if set to true, none of the webOutgoing passes are called and it's your responsibility to appropriately return the response by listening and acting on the `proxyRes` event
 *  **buffer**: stream of data to send as the request body.  Maybe you have some middleware that consumes the request stream before proxying it on e.g.  If you read the body of a request into a field called 'req.rawbody' you could restream this field in the buffer option:
