    System.out.println("Response Status Code: " + resp.get_StatusCode());

    // Examine the request we sent.
    // The LastHeader property stores the HTTP request header of the most recent request sent,
    // and in this instance, the response body mirrors the request body.
    System.out.println(http.lastHeader());
    System.out.println(resp.bodyStr());
