Lastly, handling access denial events is done by creating an
C<access_denied> private action:

    sub access_denied : Private {
        my ( $self, $c, $action ) = @_;
    }

This action works much like auto, in that it is inherited across
namespaces (not like object oriented code). This means that the
C<access_denied> action which is B<nearest> to the action which was
blocked will be triggered.

If this action does not exist, an error will be thrown, which you can
clean up in your C<end> private action instead.

Also, it's important to note that if you restrict access to "/" then
C<end>, C<default>, etc. will also be restricted.
