It is working. It is an ancient trick.
Add an alert to it so see what page is called.
You DID change http://www.example.org/myScript.php into something
sensible I presume??
<script type="text/javascript">
var myPHPScript = "http://www.example.org/myScript.php";
var milliSecSinceUE = (new Date()).getTime();
var myFakeImage = new Image();
alert (myPHPScript +"?nocache="+milliSecSinceUE);
myFakeImage.src = myPHPScript +"?nocache="+milliSecSinceUE;
</script>
