In the state page u have to set the session
<% Session ses=request.getSession(true);%>
Then set an atribute for the session.
<% ses.setAttribute("attribute","valid session");%>

Session: <% =ses.getAttribute("attribute");%>

(It will display Session: valid session)

Before you close or logout invlidate the session and remove
attribute
<% ses.removeAttribute("attribute");
ses.invalidate();%>

Everytime at the start of page we can check for the value
of sesion attribute. If it is set, then the session will be
valid. Otherwise invalid session.
