Try using javascript in your VF page like this, 
<apex:page>   
<body onLoad="noBack()">
     <script type="text/javascript"> 
            window.history.forward();      
            function noBack()          
            {               
               window.history.forward();    
            } 
     </script>
</body>
</apex:page>

Let us know if it helps.

Hello, 

This is browser behaviour rather than anything to do with Salesforce/Visualforce, so you'd need to trap the backspace key in the browser through JavaScript and block the standard behaviour.

There's more discussion and code at :http:// http://stackoverflow.com/questions/1495219/how-can-i-prevent-the-backspace-key-from-navigating-back (http:// http://stackoverflow.com/questions/1495219/how-can-i-prevent-the-backspace-key-from-navigating-back)
  
// Prevent the backspace key from navigating back.
$(document).unbind('keydown').bind('keydown', function (event) {
    if (event.keyCode === 8) {
        var doPrevent = true;
        var types = ["text", "password", "file", "search", "email", "number", "date", "color", "datetime", "datetime-local", "month", "range", "search", "tel", "time", "url", "week"];
        var d = $(event.srcElement || event.target);
        var disabled = d.prop("readonly") || d.prop("disabled");
        if (!disabled) {
            if (d[0].isContentEditable) {
                doPrevent = false;
            } else if (d.is("input")) {
                var type = d.attr("type");
                if (type) {
                    type = type.toLowerCase();
                }
                if (types.indexOf(type) > -1) {
                    doPrevent = false;
                }
            } else if (d.is("textarea")) {
                doPrevent = false;
            }
        }
        if (doPrevent) {
            event.preventDefault();
            return false;
        }
    }
});

Hope this will work. 

Thanks

Hi Everyone,

@ Bala & Karthik

Thanks for your replies.I found a Java Script which satisfied ​ my requirement.. 
<script type = "text/javascript" >
    function preventBack(){window.history.forward();}
    setTimeout("preventBack()", 0);
    window.onunload=function(){null};
    </script>
Thanks,
Vignesh.B
