Subject RE: question about Realm's scope
Date Thu, 18 Nov 2004 15:40:33 GMT

Realms can be defined at the Engine, Host, of Context level.  If they're
at the Context level, they will apply only to that webapp, so
re-authentication will be required.  At the Host level, no
re-authentication will be needed if the second webapp is in the same
Host.  Same concept for the Engine.
