URL url = new URL(webPage);  

URLConnection urlConnection = url.openConnection();  

System.out.println("Connection Timeout  =====  "+urlConnection.getConnectTimeout());  

urlConnection.setRequestProperty("Authorization", "Basic " + authStringEnc);  

urlConnection.setConnectTimeout(20000);  

InputStream is = urlConnection.getInputStream();
