Hi !
I use HttpSession for handling session in my JSP. I had set the max idle time interval for 5 minutes. I should implement a functionality which checks for session validity and should redirect to login page, if expired. How to implement this. Should I check against the session variable for null or should I check with the idle time period. Iam implementing it in multiple frames. Please give a logic with sample code of checking the session validity. Early solution is appreciated.

Thanks

you could either use the request.isRequestedSessionIdValid() or check the session variable for null, you could then use a request.sendRedirect to force the page to return to the login page. When you are in multiple frames, you might want to use a javascript jsp combination like top.document.location = <%=yourindexpage.jsp%>. This should ensure that the login page opens in the whole browser window.

sorry about the error in the post above.
response.sendRedirect should be used instead of request.
