XMLHTTP request to a password protected folder

Hello.

My site is built with heavy use of AJAX.
The site's administration folder is password protected (using .htaccess autentication, PHP, Appachie).
When the user (site admin) enters to the "adm" folder, he get a prompt for a login name and a password. Then, on the page he is provided a possibility to delete some items, and this is done using an XMLHTTP request to a php script that resides in the same "adm" folder.
Everything works fine in both Firefox 2 and IE 6 until I activate a password protection of the "adm"  folder. Since I do it, Firefox starts to thow "Permission denied to call method XMLHttpRequest.open" error. IE on my computer works, but the client's IE (probable another version) does not.

I found that the standards define a possibility to send a user name and a password with the "open" method of the XMLHTTPRequest. I failed to find any information about Firefox's support of this. And I found that some versions of IE have some problems with it. When I add a user name and a password arguments, IE give an "Invalid Syntax" error, and Firefox does not change anything and continue to give "Permission denied to call method XMLHttpRequest.open" error.

What is the right, secure and reliable way of using XMLHTTP with a user authorization?

Here is my script:

            function getRequester()
                  {
                    var xmlHttp;
                    try
                    {
                      xmlHttp = new XMLHttpRequest();
                    }
                    catch(e)
                    {
                      var XmlHttpVersions = new Array("MSXML2.XMLHTTP.6.0",
                                                      "MSXML2.XMLHTTP.5.0",
                                                      "MSXML2.XMLHTTP.4.0",
                                                      "MSXML2.XMLHTTP.3.0",
                                                      "MSXML2.XMLHTTP",
                                                      "Microsoft.XMLHTTP");
                      for (var i=0; i < XmlHttpVersions.length && !xmlHttp; i++)
                      {
                        try
                        {
                          xmlHttp = new ActiveXObject(XmlHttpVersions[i]);
                        }
                        catch (e) {}
                      }
                    }
                    if (!xmlHttp)
                      alert("Error creating the XMLHttpRequest object.");
                    else
                      return xmlHttp;
                  }



            function del(y, m, n, spn){
                requester=getRequester();
                adr="adm/del.php?y="+y+"&m="+m+"&n="+n;
                requester.open("GET", adr, true);
                requester.send(null);

                iss=spn.parentNode;
                iss.parentNode.removeChild(iss);
            }


Thanks in advance. Kosta.
