Redirect IE8 users to a different page

My entire home page is an animation, with several different links on it. But it doesn't work on IE8, since that browser doesn't support html5.

I want to add a redirect for IE8, 7, 6 users to a different home page. I searched and found several java scripts I could add, similar to the ones below. I  added them to the html file that was generated by edge after publishing. I  tried adding them in the head. Didn't work. Tried adding after

<div id="Stage" class="EDGE-88555059">

    </div>

Again, nothing.

<!--[if IE 8]>

<script type="text/javascript">

window.location = "http://www.google.com/";

</script>

<![endif] -->

Also tried

<!--[if lt IE 9]> <div>

<a href="http://www.google.com" TARGET="_blank">

</a></div> <![endif]-->

Please help! Thanks -- Jami
