You had added it and have now removed it?
The normal session id is created when you access a JSP for the first
time, unless you have specifically configured JSPs to not create a
session. A session can also be created manually by a Filter or a Servlet.
The SSO session is created when the container login process completes
authentication successfully.
I'm not entirely clear on when SSO replication occurs - presumably only
when there's a change like session invalidation or creation.
