Hi,
request.getSession(false) actually may not get u null,
for instance if u invalidate a session, then all the
values stored in session are removed, but u still get
the session, so it is not null
so i would suggest u not only check for session ==
null but also some value u know ill be in session,
if this attribute is also null, then u can forward the
request to logout
your code will look some thing like this
<% if (request.getSession(false) == null) { %>
<jsp:forward page="logout.jsp?TIMEOUT=60">
</jsp:forward>
<%
}
if (request.getSession(false).getAttribute("myvalue"
== null) { %>
<jsp:forward page="logout.jsp?TIMEOUT=60">
</jsp:forward>
<%
}
%>
%>
