Cache busting

[Pain]

Hi.

 

I have a very common problem, IE caches stuff, so in order to see new things come up i must reload all page.

 

function mountOne()
{

var myurl = 'mount_shotgun.php';
myRand = parseInt(Math.random()*99999999); // cache buster

var xmlhttp2;
if (window.XMLHttpRequest)
{
	xmlhttp2 = new XMLHttpRequest;
}

xmlhttp2.onreadystatechange = function()
{
	if (xmlhttp2.readyState == 4 && xmlhttp2.status == 200)
	{
		document.getElementById("retrieve").innerHTML=xmlhttp2.responseText;
	}
}


$('#inventory_item1').css("background-image", "url('images/shotgun.png')");

xmlhttp2.open("GET", myurl + "?rand=" + myRand, true);

   xmlhttp2.send();



}

 

My attempt to bust it using a random token was unsuccessfull

 

var myurl = 'mount_shotgun.php';
myRand = parseInt(Math.random()*99999999); // cache buster

 

I would gladly appreciate any kind of help. Thank you.

You can just set the HTTP cache headers, in order to stop the browser (or anything else) from caching the pages.

i've tried

header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");

but nothing has changed..
