MainFrame - Possibilities?

Could anyone tell me how to make a mainframe and to fit in a website within itself? these are some of the HTTP typed mainframes i picked up:

Code:

---

<script type="text/javascript">
  var http = (window.XMLHttpRequest) ? new XMLHttpRequest() :new ActiveXObject("Microsoft.XMLHTTP");

  function rate(game, rating) {
    var obj = document.getElementById('rating');
    obj.innerHTML = 'Loading...';

    var url = '/rate.php?g_id=' + game + '&rating=' + rating;
    http.open('get', url);
    http.onreadystatechange = responseHandler;
    http.send(null);
  }

  function responseHandler() {
    if(http.readyState == 4) {
      var obj = document.getElementById('rating');
      if(http.status == 200) {
        obj.innerHTML = http.responseText;
      } else {
      obj.innerHTML = 'Error!';
      }
    }
  }
</script>

mmm I don't know how to use that in Flash though.... :doughnut:


p.s. If such mainframe is possible - could anything stop the website - e.g. a school RM filter? :p

come on guys.. any link would be possible.
