Description (last modified by Filip Dimitrovski)

The current implementation in django.contrib.auth.views.LogoutView allows both GET and POST requests without any CSRF protection. A simple 

   <img src="http://djangoapp/logout" />

on an exploit page could log out the user. While this is a low security risk, it's still a DoS issue and could prevent the user from using the app.

Instead of fixing the view, it maybe makes sense to just change the ​docs to warn the programmer of such a problem and suggest overriding LogoutView and changing dispatch().
