Hi, I used the code below for a function that I have to repeat with the same
code. Samething like the stars in gmail for example that with one click I
sign a message, with the second I sign-off the message.
My code work perfect with Firefox but with Mozilla it work only the first
time that I click the command. I hope my question clear. Sorry for bad
English and thanks for your answers. Stefano.

Ho usato il codiceseguente che sotto mozilla funziona bene, sotto IE mi
funziona solo la prima volta, dalla seconda in poi mi ripete la stessa
cosa...cosa devo cambiare?grazie.

var http_request = false;

  function makeRequest(url) {

      if (window.XMLHttpRequest) { // Mozilla, Safari,...
          http_request = new XMLHttpRequest();
      } else if (window.ActiveXObject) { // IE
          http_request = new ActiveXObject("Microsoft.XMLHTTP");
      }
      http_request.onreadystatechange = alertContents;
      http_request.open('GET', url, true);
      http_request.send(null);

  }

  function alertContents() {

      if (http_request.readyState == 4) {
          if (http_request.status == 200) {
              alert(http_request.responseText);
          } else {
              alert('There was a problem with the request.');
          }
      }

}
