Examples of org.apache.shiro.subject.Subject.logout()

org.apache.shiro.subject.Subject.logout()
Logs out this Subject and invalidates and/or removes any associated entities, such as a {@link Session Session} and authorization data. After this method is called, the Subject isconsidered 'anonymous' and may continue to be used for another log-in if desired.
Web Environment Warning
Calling this method in web environments will usually remove any associated session cookie as part of session invalidation. Because cookies are part of the HTTP header, and headers can only be set before the response body (html, image, etc) is sent, this method in web environments must be called before any content has been rendered.
The typical approach most applications use in this scenario is to redirect the user to a different location (e.g. home page) immediately after calling this method. This is an effect of the HTTP protocol itself and not a reflection of Shiro's implementation.
Non-HTTP environments may of course use a logged-out subject for login again if desired.

                                "unexpected but not critical: it can be safely ignored because the " +
