This simple script operates the same way as the back button in a visitor's browser.
<a href="#" onClick="history.go(-1)">Back</a>
Where possible, you should also include the previous page in the href section of the link. For instance in PHP you can access the referrer as below:
<?php $referrer=$_SERVER['HTTP_REFERER']; ?>
