Consecutive AJAX call issue

[Jay Abrahm]

I have the following javascript which hits the server only the first time I make the call

function validate() {
var url = "ValidateAction_validateText.action?validateText="+validateTexts;
if (typeof XMLHttpRequest != "undefined") {
req = new XMLHttpRequest();
} else if (window.ActiveXObject) {
req = new ActiveXObject("Microsoft.XMLHTTP");
}
req.open("GET", url, true);
req.onreadystatechange = callbackDelete;
req.send(null);
}

Because you are storing things in global variables, you will not be able to make simultaneous requests. Is that the issue?
