I did try to do this starting with a simple example i.e. a listener which
only counts the active sessions. This works quite well now but i noted
that a logut did not invalidate the session (meaning that if a user did
log out i still had the same number of sessions).
The reason is that session.invalidate(); is not called in logout.xsp. If
i add it to login.xsp:
<xsp:content><uri><xsp-request:get-context-path/><xsp:expr>uri</xsp:expr></uri></xsp:content>
}
}
+ session.invalidate();
}
</xsp:logic>
</logout>
i got the proper number of sessions. Is this a bug or is
session.invalidate not called on purpose?
