            con.setFollowRedirects(true);
            con.setInstanceFollowRedirects(true);
            con.connect();
           
            BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream()));
           
            String s = "";         
            StringBuffer sb = new StringBuffer();         
            while ((s = br.readLine()) != null){
                sb.append(s + "\r\n");
