  • And why should it be 1 session and not 4? You can do concurrent requests and if you use JSP you will always get a session (even if it is a temporary one). You can counter act this by adding `session="false"` to your JSP see http://stackoverflow.com/questions/5093032/how-do-you-disable-session-creation-for-all-jsps-with-tiles – M.

  • You are using Spring Security then use Spring Security. Judging by the fact that you are extending the `HttpSessionEventPublisher` I also assume you have something for concurrent sessions or session management in place and hence a `SessionRegistry` use that. – M. Deinum Oct 19 '15 at 13:06
