=head1 NAME

Catalyst::Request::REST - A REST-y subclass of Catalyst::Request

=head1 SYNOPSIS

     if ( $c->request->accepts('application/json') ) {
         ...
     }

     my $types = $c->request->accepted_content_types();

=head1 DESCRIPTION

This is a subclass of C<Catalyst::Request> that applies the
L<Catalyst::TraitFor::Request::REST> role to your request class. That trait
adds a few methods to the request object to facilitate writing REST-y code.

This class is only here for backwards compatibility with applications already
subclassing this class. New code should use
L<Catalyst::TraitFor::Request::REST> directly.

L<Catalyst::Action::REST> and L<Catalyst::Controller::REST> will arrange
for the request trait to be applied if needed.

L<Catalyst::TraitFor::Request::REST>.
