hi all, i tried following code for session management bt i dnt knw where it went wrong? can anyone please help me solve the problem. i want to restrict user going on the prevoius page after logging out when he clicks on the browser's BACK button.
******************************************************************
1) i created login.jsp as follows:
<p><a href="1.jsp">1</a></p>
<%@ page contentType="text/html;language="java" import="java.sql.*">
<%
String username="vishal";
request.getSession();
out.println("<br>new session created");
session.setAttribute("username",username);
out.println("<br>"+session.getAttribute("username"));
%>*********************************************************************
2) then i created 1.jsp as follows:
<%@ page contentType="text/html;language="java" import="java.sql.*" %>
<html>
<body>
<p><a href="logout.jsp">logout</a></p>
<%
if(session.getAttribute("username")==null)
response.sendRedirect("Error.htm");
%>
</body>
</html>**********************************************************************
3) logout.jsp would be :
<%
if(session.getAttribute("username")==null)
response.sendRedirect("Error.htm");
else
{
session.setAttribute("username",null);
session.invalidate();
response.sendRedirect("login.jsp");
}
%>*********************************************************************
but above code is not working. can anybody solve this problem? pls? or at least give some modification to it???
