4.3.1 Example Usage

<script type="text/ecmascript" src="scripts/1.0/bsm.web2connect.js"></script>

<script language="text/ecmascript">
  var w = new Web2Connect();
  w.Session.Protocol = "http";
  w.Session.Host = "localhost";
  w.Session.Port = "80";
  w.Session.Username = "admin";
  w.Session.Password = "formula";
  w.createSession(logonSuccess, logonFail);
  function logonSuccess()
  {
    alert("yippee!");
    w.deleteSession(null, null);
  }
  function logonFail()
  {
    alert("boo hoo");
  }
</script>

All methods must be passed references to handler functions for success and fail asynchronous callbacks. Null references can be used if callbacks are not required.
