Session expire and back button in jsp and servlet .

Hii Sir, I have to make a login and logout page with sessions .Now i have to invalidate

the session after a certain interval of time and after clicking logout button.Means that

after session expiry time and logout action no one can access previous pages by clicking

back button of browser without again logging.

Use session.invalidate() method to close the session.Here is an example.

1)login.jsp:

<html>

<head>

<title>User Login</title>
</head>
<br>
<body Bgcolor ="#0099cc"><hr><hr>

<form method="POST" action="action.jsp">
<p><b>UserName:</b> <input type="text" name="UserName" size="10"></p>
<p><b>Password:</b>   <input type="Password" name="Password" size="10"></p>
<p><input type="submit" value="Submit" name="submit"><input type=
"reset" value="Reset" name="reset"></p><hr><hr>
</form>

</body>

</html>

2)action.jsp:

<%@page import="java.util.*" %>
<script>
function go() {
window.location.replace("logout.jsp",'window','toolbar=1,location=1,directories=1,status=1,menubar=1,scrollbars=1,resizable=1');
self.close()
}
</script>
<%String str = request.getParameter("UserName");
session.setAttribute("UserName", request.getParameter("UserName"));%>
Welcome to <%= session.getAttribute( "UserName" ) %>
<% if (session.getAttribute("UserName").equals("")){%>
<a href="login.jsp"><b>Login </b></a>
<%}
else{%>
<a href="javascript:go()"><b>Logout</b></a>
<%}
%>

3)logout.jsp:

<%session.invalidate();%>
You have logged out. Please
<a href="a.jsp"><b>Login</b></a>
