Just to re-emphasize some important points with this: 1. I am, in fact, doing a redirect to the home page immediately after the logout call. It never gets there, though, because the exception occurs somewhere along the filter chain.
2. The exact same code, with the exact same Shiro version, worked in Grails 1.3.9, but doesn't in Grails 2.x. So something has changed in the way Grails is handling sessions (?) with resulting problems for Shiro native sessions. I'm trying to work out what that might be, to see if I can effect a workaround. (I've asked about this over on the Grails mailing list too). -- View this message in context: http://shiro-user.582556.n2.nabble.com/What-might-cause-an-UnknownSessionException-tp7578179p7578196.html Sent from the Shiro User mailing list archive at Nabble.com.
