Hi, I have 2 applications on 2 different servers, If I logout from one application and go to the other still I successfully login into other application. I think if I logout from fisrt application I shd not be able to login into second applications. the other problem is, now from second application if I go back to first application, I again get principal in first application request.getUserPrincipal(), everything runs ok again but the moment I put anything into session it throws exception saying that this session is already invalidated, whcih is true coz I inavildated the session when I logout from first application. is there anything we can do, I mean when i logout from any application i shd be logged out from all application?
