Disabling back button in JSP after logging in?

(Disabling back button in JSP after logging in?)

What does this code mean? Anyone pls explain this following code.Because, I never studied about this 'response.setHeader' method.

<%
response.setHeader("Cache-Control","no-store");
response.setHeader("Pragma","no-cache"); 
response.setHeader ("Expires", "0"); //prevents caching at the proxy server
%>

or any other methods are available for disabling back button in JSP after Logging in?

If you want to restrict the user to go back then try this small script.

<script>
    history.forward();
</script>

Put this code into the <head> element of your page and try to go back. For more details click on following link...

You can do this using JavaScript, for example by asking user not to go away from the page.

window.onbeforeunload = function() { return "You work will be lost."; };
