Controlling basic HTTP authentication with javascript

Question

I want to check if the URL is protected by basic Http authentication using javascript. Here is what I still have:

  function showFailure(){ alert("FAILED ") }
  function showSuccess(){ alert("SUCCESS") }

  var myRequest = new Request({
    url: 'http://localhost/access_protected_HTTP_BASIC', 
    method: 'get', 
    onSuccess: showSuccess,
    onFailure: showFailure
  }).send();

But it does open a browser login popup to access the resource. Is there a way to not trigger this popup?

Thank!

Note. I use mootools in this example, but I would take any javascript example that does the trick :)
