53 =head1 DESCRIPTION
54
55 This is a subclass of C<Catalyst::Request> that applies the
56 L<Catalyst::TraitFor::Request::REST> which adds a few methods to
57 the request object to faciliate writing REST-y code.
58
59 This class is only here for backwards compatibility with applications
60 already subclassing this class.
61
62 L<Catalyst::Action::REST> and L<Catalyst::Controller::REST> will arrange
63 for the request trait to be applied if needed.
