 Redirecting to the login page whenever a REST response uses a 401 status code is usually not enough. React-admin keeps data on the client side, and could briefly display stale data while contacting the server - even after the credentials are no longer valid.
 
-Fortunately, each time the user navigates to a list, edit, create or show page, react-admin calls the `authProvider.checkAuth()` method. If this method returns a rejected Promise, react-admin calls `authProvider.logout()` and redirects the user to the login page. So it's the ideal place to make sure  the credentials are still valid.
