Setting org.icefaces.sessionExpiredRedirectURI to a valid URI tells ICEfaces that when the user session expires, that the client is to be redirected to the specified page. When using ICEpush, or icecore:refresh, the user will be redirected automatically on session expiry. Otherwise, they will be redirected on the next request after session expiry.
