Fixed a typo:
The basic use case is this: User clicks on a link that requires_login and gets redirected to the login page. After login the user is redirected to the original requested page. Exceptions: - the login is outsourced to janrain - the login is outsourced to cas or other open-id - the login is not possible and the user must first register - after login is redirected to the intended page but the app logic finds this user has incomplete profile and redirects to profile editing (*) - what if the user is impersonating another user? (?) - the user is visiting a page that does not require login but LOADs a component that does (?) - the user is visiting a page that does not require login but IFRAMEs a component that does - the user has another window open (**) (*) is not currently supported. (?) not sure if it works (**) worked with _next but not not with session._auth_next.
