    Resolution: Duplicate

> Refresh cached session in HTTP request after user logs out
> ----------------------------------------------------------
>                 Key: SHIRO-639
>                 URL:
>             Project: Shiro
>          Issue Type: Bug
>          Components: Authentication (log-in), Subject, Web
>    Affects Versions: 1.3.2
>         Environment: Jetty 9.4.5, Wicket 7.7.0
>            Reporter: Philipp Kapfer
>              Labels: patch, usability
>         Attachments: ShiroHttpServletRequest.patch
> For native session management in web environments, the _ShiroHttpServletRequest_ caches
calls to _getSession()_ by saving a copy of the current subject's session to a member variable.
This copy is never updated even when the subject logs out and the session is destroyed.
> When the session is accessed again after logout, an {{UnknownSessionException}} can be
thrown because the session referenced in the request is not physically available anymore (this
could be the cause for [SHIRO-614|]).
> The Shiro HTTP request therefore has to check the state of the cached session and refresh
it if necessary, just as the original Jetty Request class does as well.
> Please see the attached patch for a possible solution that Works For Me™
