Internet Explorer Caching

[millsy007]

Hi, I know this is a fairly common issue, and I have tried a number of methods (adding a random number to the GET, changing the GET to POST etc.) But I still get the same issue of internet explorer working with an old recordset that the user has since updated on my page.

 

What happens is the user inserts a record (into my coach booking form) but when the user clicks to show the schedule the changes are not reflected in internet explorer, how can I force my function to work with the latest set of data?

 

The floowing is the function that is used to show the latest schedule:

 

<script  type="text/javascript">
<!-- 
//Browser Support Code
function GetSchedule(){
var ajaxRequest;  // The variable that makes Ajax possible!

try{
	// Opera 8.0+, Firefox, Safari
	ajaxRequest = new XMLHttpRequest();
} catch (e){
	// Internet Explorer Browsers
	try{
		ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
	} catch (e) {
		try{
			ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
		} catch (e){
			// Something went wrong
			alert("Your browser broke!");
			return false;
		}
	}
}
// Create a function that will receive data sent from the server
ajaxRequest.onreadystatechange = function(){
	if(ajaxRequest.readyState == 4){
		var ajaxDisplay = document.getElementById('ajaxDiv');
		ajaxDisplay.innerHTML = ajaxRequest.responseText;
	}
}
var date = document.getElementById('date').value;
var time = document.getElementById('time').value;
//	var queryString = "?date=" + date + "&time=" + time;
//	
//	ajaxRequest.open("GET", "getschedule.php" + queryString,+'&nocache = '+nocache true);
//	ajaxRequest.send(null); 


var date = document.getElementById('date').value;
var time = document.getElementById('time').value;
var queryString = "?date=" + date + "&time=" + time;
ajaxRequest.open("GET", "getschedule.php" + queryString, true);
ajaxRequest.send(null); 

}

</script>
