available.6. If the session object is invalidated can it be again regained or refreshed7. From the current Browser window, if we open a new Window, then it referred to as Multiple

Windows. Are Sessions properties are maintained across all these windows, even though they areoperating in multiple windows?

8. HttpSession.setMaxInactiveInterval() can manage the inactivity lease period on a per-session basis.9. While using request.getRequestDispatcher(path) we need to give the absolute path of the object10. When you createna Cookie object, you must call setMaxAge before sending the cookie to the

client.11. A session does not works when a clienthas disabled cookies in their browser.12. The duration of an HTTP session is configurable on the Web server.13. Automatically expiring sessions after a period of inactivity ensures that web server resources are



bound by old sessions.14. An explicit log out immediately expires the session.15. Sessions are lost if one or more servlets in an application do not call the encodeURL() or

encodedRedirectURL() methods.16. HttpSession object has a built-in data structure that allows storing any number of keys and

accessed the server.18. The last access time is the value the servlet engine uses to determine when the session has timed

out.19. Every client of a site is associated with a javax.servlet.HttpSession object that Servlets can use to

store or retrieve information about that client.20. In cookies, either relative or absolute URLs can be used by the web site without losing state.
