// Imagine a URL that contains two params: one named "xyz" and one named "name".
// We want to send a POST to it, but with 2 additional params in the body of the request.
// The PostUrlEncoded method cannot be used because it parses the URL and puts all the params
// in the HTTP body.  The SynchronousRequest method should instead be used so
// that the req.Path can be explicitly specified.
