access denied

Hi everyone,

I'm new to newsgroups, therefore sorry in advance if I don't follow propper
protocol...

I have a problem with access control in IE.

The implemented architecture is all processed in the client side, and the
webserver is just a dumb file server.

Problem:

I Have 2 directories.

One is public, with HTML/Js/XSLT.

The other has access control implemented be the webserver, requiring login
and pw.

When I run the page from firefox, it works fine, asking for the pw whenever
I first access the xml file in the "private" directory.

The problem arrises when I use IE. IE refuses to ask for thw login/pw, and
throws an "Access is Denied" exception.

Since I want cross browser functionality, i'm stuck. HAve lost 2 days of
research and found nothing...

Here's the JS function:

function loadXmlFileToDom ( xmlDocFileName ) {

 var xmlDocLoad = null;

    if( document.implementation && document.implementation.createDocument )
{
    // MOZILLA

     xmlDocLoad = document.implementation.createDocument( "", "", null );
  xmlDocLoad.async = false;
     xmlDocLoad.load( xmlDocFileName );

 } else if( window.ActiveXObject ) {
    // IE

  xmlDocLoad = new ActiveXObject('MSXML2.FreeThreadedDOMDocument');
  xmlDocLoad.async = false;

  try {

   xmlDocLoad.load( xmlDocFileName );

  } catch ( errorObject ) {

   alert ( errorObject.description + ": " + xmlDocFileName + "\n" +
(errorObject.number & 0xFFFF )+"\n" + errorObject.number + "\n" +
errorObject.name +"\n" +  errorObject.message );

  }

 }

 return (xmlDocLoad);

}

Best regards, and thanks !
