Ajax call is not working in Internet Explorer9 and Internet Explorer10

i used this function to display item page using ajax. it is working fine on Chrome.but not in internet explorer.

<script type="text/javascript">
    function grabInfo(str)
    {
        if (str=="")
        {
            document.getElementById("contentDiv").innerHTML="";
            return;
        }
        if (window.XMLHttpRequest)
        {
            // code for IE7+, Firefox, Chrome, Opera, Safari
            xmlhttp=new XMLHttpRequest();
        }
        else
        {
            // code for IE6, IE5
            xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
        }
        xmlhttp.onreadystatechange=function()
        {
            if (xmlhttp.readyState==4 && xmlhttp.status==200)
            {
                document.getElementById("contentDiv").innerHTML=xmlhttp.responseText;
            }
        }
        xmlhttp.open("GET","get_property.php?q="+str,true);
        xmlhttp.send();
    }
</script>

This function is returning the updated results on Chrome.But in Internet Explorer, this function returns the previous results.If i clear sessions using Ctrl+Shift+Del, system shows updated results.why is this happening? Can you help on this?

Thanks in Advance....

The issue is that IE caches the request, as long as query string doesn't change it returns the same response, this can be handled by server side headers,

Cache-Control: no-cache, no-store

but the easiest way is just to modify the request like this:

xmlhttp.open("GET","get_property.php?q="+str+"&r="+Math.random(),true);

Internet Explorer caches responses. You can either add a random value to the request URL's query string using Math.random() or include a response header in the server-side script.

Cache-Control: no-cache, no-store
