Java EE (Java Enterprise Edition) General Discussion

What is best way of handling http session time out issues in JSF?
We have the following solution with a servlet filter
We wrote a servlet filter and we are redirecting to sessionTimeOut.faces by checking if session has been timed out.

But the problem is the redirection to sessionTimeOut.faces is happening for only some requests and for all requests.
For example when we use <hx:requestLink, on click of this link if the session times out we are getting response already committed exception as below.

Any thoughts what is going wrong here?
