IMO the best option would be to create a filter checking if(
session.isNew() ) { doSomething(); }. Of course, that'd make it 2.3-only.
BTW, that's a very good point - when session is created, it's created
because of an incoming request, so it would be a nice addition something
like HttpSessionEvent.getRequest() to get the request causing session's
creation in HttpSessionListener.sessionCreated()? Anyone working on Servlets
2.4 specs here, what do you think?
