Session in JSP Posted: Apr 21, 2006 5:36 AM

Hi,
I have succesfully created session in a JSP page.
I put name and pasword in a form in index.jsp and then send it
to login.jsp where I start the session.
In login.jsp I am also using an EJB in which I am
connecting to a database and finding out if an user is
in that database.If he is there , I start the session.
In next page I am trying to logout by using : session.removeValue().It removes the session value but when
I click "back" in the browser,the login.jsp page behaves like the session would be still created.

Could you help me with it please?

On logout don't use removerUser() try this....
...................
HttpSession session=request.getSession(false);
if(session!=null){
session.invalidate();
}
..................

How exactly should I use it.
Here is the code:

<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<% if(session.getValue("meno")!=null)
{
session.removeValue("meno");

%>
<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css" />
</head>
<body>
<div class="cele">
<div class="hlavicka"><h1 class="hlavicka">Hlavička</h1></div>
<div class="lave">
<p><a href="index.jsp">Prihlasenie</a></p>
</div>
<div class="prave">

<p>Prave</p>
</div>
<div class="obsah">
<%
out.println("<h2>Bol si odhlaseny</h2>");
%>
</div>

<div class="spodok"></div>
</div>
</body>
</html>
<%
}
else
{
%>
<%@ include file="index.jsp" %>
<%
}
%>
