In order to replicate the forward and back button functionality you can use the following Javascript functions :
<script type="text/javascript"> <!-- function goBack() { history.go(-1); } function goForward() { history.go(1); } //--> </script>
<a href="javascript:history.go(-1);">Go back</a> <a href="javascript:history.go(1);">Go Forward</a>
<form> <input value="Back" onclick="history.go(-1); return true;" type="button"> <input value="Forward" onclick="history.go(1); return true;" type="button"> </form>
