this is what I figured out
<script type="text/javascript">
function ChangeUrl(title, url) {
if (typeof (history.pushState) != "undefined") {
var obj = { Title: title, Url: url };
history.pushState(obj, obj.Title, obj.Url);
} else {
alert("Browser does not support HTML5.");
}
}
</script>
<body onload="ChangeUrl('index.html', 'index.html');">
