Thank you for your answer! I have done some tests now, and you're right, =
it wasn't enough to just do SSLSession.invalidate(). But if I also close =
the socket, by doing

response.setHeader("Connection", "close")

it seemed to work. But when I read your message I realize that there =
might be other sockets open that also need to be closed.

Hi,

I think calling SSLSession.invalidate() will not suffice to logout the=20
user. Because calling invalidate() will only prevent the client to open=20
a new SSL-connection using the the same session, but has no influence on =

existing ssl-connections using that session. That means the user is not=20
logged out until all connections using that session are closed.
See also the java api:=20

alidate()
