Help with AJAX xmlhttp and sending a value back

[StealthRT]

I am trying to figure out how to SEND something to this code from my ASP page. I am calling this fuction by checkLogin(checklogin.asp, this.form) and everything works BUT i can not tell if the user was FOUND or NOT FOUND.

I had loggedIn set as an ASP Session but that wont work since the page needs to be refreshed in order to see those changes. How can i get a value from the checklogin.asp page after its goes into the "xmlhttp.status == 200" portion of the code?

function checkLogin(url, formArray) {
var parameters = "";

for(i=0; i < formArray.length; i++) {parameters = parameters + formArray[i].name + "=" + encodeURIComponent(formArray[i].value) + "&";}
xmlhttp.open("POST", url + '?' + Math.random(), true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.setRequestHeader("Content-length", parameters.length);
xmlhttp.setRequestHeader("Connection", "close");
xmlhttp.send(parameters);
xmlhttp.onreadystatechange = function() {
     if (xmlhttp.readyState == 4) {
	if (xmlhttp.status == 200) {
		if (loggedIn  == 'NO'){
			window.parent.openBoxShow('You were not found... try again?','')
		}else{
			window.parent.openBoxShow('You are now signed into the site!','RELOAD')	
		}
        }
        else {
                alert('An error occurred: ' + xmlhttp.status + ' ' + parameters);
        }
       	}
}}

Any help would be great
