Check if Browser is IE and Which Version of IE with HTML

Check if the browser is using IE8

<!--[if IE 8]> 
	<script src="_ie8.js"></script>
<![endif]-->

This stylesheet will only display to IE9 or above, along with every other non-IE browser. Notice opening and closing expressions are wrapped in comments.

<!--[if gt IE 8]><!-->
	<script src="_nonIe8.js"></script>
<!--<![endif]-->

**Make sure the src path reference begins with a slash (/scripts/myscript) and not use the root tilde reference. This (~) doesn’t seem to work within the conditional hthml.
