      HttpClient client = new DefaultHttpClient(); 
      HttpGet request = new HttpGet(url); 
      // add request header 
      request.addHeader("User-Agent", "Mozilla/5.0"); 
      HttpResponse response = client.execute(request); 
      System.out.println("\nSending 'GET' request to URL : " + url); 
      System.out.println("Response Code : " +

      BufferedReader rd = new BufferedReader(
          new InputStreamReader(response.getEntity().getContent())); 
      StringBuffer result = new StringBuffer(); 
      String line = ""; 
      while ((line = rd.readLine()) != null) { 
       result.append(line); 
      } 
      System.out.println(result.toString()); 
     } 

    }
