a4j:poll and sesstion timeout

[martind1111]

I am using Tomcat 6.0.18 with JSF 1.2 (Sun RI) and RichFaces 3.3.0. I would like to build a page that would report application status. I would like to use a4j:poll to refresh the status value. I have created such a page and it works as expected. However, one thing I noticed is that my authenticated sessions are not timing out anymore after I added the a4j:poll. It looks as though every time the client polls the server for data, the session time-to-live value is reset. I am wondering if there is a way to get around this. I would like my sessions to still time out if the user isn't clicking any controls on the page, regardless how many times portion of the page is refreshed because of a4j:poll.

Hi Martin,

What type of state saving do you use?

[martind1111]

The javax.faces.STATE_SAVING_METHOD property is set to server in my application.

a4j:poll creates the same request as commandButton or support. So it goes through the lifecycle and session kept alive.

Is there a construct in RichFaces that would allow me to refresh a portion of the screen without impacting the time-to-live session timeout?

a4j:push polls the server with minimalistic head requests and not goes through JSF lifecycle. But if event available it sends normal request. So your session will not be kept if you will use push and there will be no updates needed during timeout time. In the other case session will be also restored.

You can implement session invalidation on timeout programmatically using listeners defined in Servlet API.
