  function changeHashOnLoad() {
      window.location.href += "#";
      setTimeout("changeHashAgain()", "50");
  }
  
  function changeHashAgain() {
      window.location.href += "1";
  }
  
  var storedHash = window.location.hash;
  window.setInterval(function () {
      if (window.location.hash != storedHash) {
          window.location.hash = storedHash;
      }
