HttpURLConnection connection = null;
try{         
    URL myurl = new URL("http://www.myURL.com");        
    connection = (HttpURLConnection) myurl.openConnection(); 
    //Set request to header to reduce load.       
    connection.setRequestMethod("HEAD");         
    int code = connection.getResponseCode();        
    System.out.println("" + code);
