Subject Re: Invalidate the SSLSession?
Date Thu, 05 Jan 2006 16:12:09 GMT
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 
user. Because calling invalidate() will only prevent the client to open 
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 
logged out until all connections using that session are closed.
See also the java api: 
http://java.sun.com/j2se/1.5.0/docs/api/javax/net/ssl/SSLSession.html#invalidate()
