            xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
        if(window.XMLHttpRequest)
            xmlHttp=new XMLHttpRequest();

        createXMLHttpRequest();
        xmlHttp.open("GET","http://www.first.com/cookie.php",true);
        xmlHttp.onreadystatechange=getcookie;
        xmlHttp.send(null);

    function getcookie(){
        if(xmlHttp.readyState==4){
            if(xmlHttp.status==200){
                var reply=xmlHttp.responseText;
                if(reply){
                    alert(reply);
                }
            }
