     //System.out.println("Testing 1 - Send Http GET request"); 
     //http.sendGet(); 

     System.out.println("\nTesting 2 - Send Http POST request"); 
     http.sendPost(); 

    } 

    // HTTP GET request

     DataOutputStream wr = new DataOutputStream(con.getOutputStream());

     int responseCode = con.getResponseCode();
