Session expires even doing operations on pop up Window (Window.open)

On our Application , We have HyPer Links on our Grid .(Result Display) On click of that a new Pop Up Window is opened , using 开发者_如何学Gowindow.open pop up mechanism We can do several operations on that newly opened window like Insertion , Deletion ,Updation of data with respect to DataBase .

The issue is that , even though we are doing several operations on our Database , the session is being expired on to the Application .

Not easy to provide an answer. It highly depends on your environment. Maybe your application server does not only rely on JSESSIONID, it may use cookies provided by a certain SingleSignOn system. Those cookies may have a fixed lifetime. Trace your HTTP requests / responses using Firefox Firebug or WebKit (Chrome) developer tools and check which cookies are exchanged. If necessary define a javax.servlet.http.HttpSessionListener and track the application server's behaviour.
