Page Expiration in wicket

I have a wicket Project and My page is Expiring so fast. why?

From stackoverflow JGC

• I assume that by "My page is Expiring" you mean that the session is expiring? If so, you can increase the session-timeout in the web.xml of your project:

  <session-config>
          <session-timeout>30</session-timeout>
  </session-config>
  

  The timeout is specified in minutes.

  From jsight

• in web.xml increase the session timeout 30 is 30 minutes increase the time as 200 session-config> 30

• You can also do this programatically, by getting the HttpSession of the request and setting MaxInactiveInterval.

  Integer timeoutInMinutes = 20;
  Request request = RequestCycle.get().getRequest();
  if( request instanceof WebRequest )
  {
      WebRequest wr = (WebRequest)request;
      HttpSession session = wr.getHttpServletRequest().getSession();
      if( session != null ) {
          session.setMaxInactiveInterval(timeoutInMinutes*60);
      }
  }
