    // The example above downloads http://www.yahoo.com, saves it into 
    // a file named yahoo.html (you can use a full path here, if desired), and 
    // refreshes the content every 600 sec (10 min) as needed.

                        touch($file); // Mark it as fresh so that not every hit retries (retry once per expire interval)
