how to make link same as back button?

[Technetium]

I have a page that can be accessed from many other pages. There is a single link on that page that says "Back". I know it is possible through javascript to make that link function the same as pressing the browser's back button, but I can't remember how. I'm aiming for Mozilla compliancy, so it can't be something that involves IE-only language.

<a href="javascript:void(0);" onclick="history.go(-1)">Back</a>

The example above is perfectly valid as is but you will end up with a dead link for the 13% fo users that do not use JavaScript. Consider drawing the link with JavaScript to avoid the embarrassment.

<script type="text/javascript">
<!--
document.write('<a href="#">Back</a>');
document.links[document.links.length-1].onclick = function () {history.back(); return false}
// -->
</script>
