disable caching while using ajax script

I am running an ajax script that calls a php script that runs a query and returns the values to a specific div.

The problem I am running into is that when I refresh the page the webpage wants to use the cashe because it will load faster, I want it to run the ajax script so it will run the query and show me the updated information...

I guess I need to disable to cashe...Thats what I am not sure how to do..

Not a pro at that, but as far as the php script is concerned you can usually use headers to force no cache:

header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past

See http://php.net/manual/en/function.header.php.

make a new url everytime
var myTime = myDate.getTime();
var url=’http://localhost/call_to_ajax.php?rand=’+myTime;
http.open(‘GET’, url);

this will make sure that request goes to server every time
