Explicit, forced expiration of the HTTP session in any SSO enabled web
application should destroy the SSO session and in turn trigger the
expiration of the HTTP session for every other SSO enabled web application.

Session expiration due to timeout in an SSO enabled web application only
terminates the HTTP session for that web application. The SSO session is
unaffected (unless this was the last HTTP session associated with the
SSO session in which case the SSO session is removed).
