How to validate session before invalidate

[jfuture_99]

Before I call session.invalidate(), how can I make sure the session
has not been invalidate already because it will throw an exception if
it has.

Thanks

I haven't tested these possiblities but you can give it a go:
- use HttpSession.isNew()
- Get the session back from the request object again
session = request.getSession(false);
if(session != null)
{
session.invalidate();
}

- or
session = request.getSession(true);
if(!session.isNew())
{
session.invalidate();
}
