=head1 DESCRIPTION

This is the Catalyst Response class, which provides methods for responding to
the current client request.

=head1 METHODS

=head2 $res->body($text)

    $c->response->body('Catalyst rocks!');

Sets or returns the output (text or binary data).

=head2 $res->content_encoding

Shortcut for $res->headers->content_encoding.

=head2 $res->content_length

Shortcut for $res->headers->content_length.

=head2 $res->content_type

Shortcut for $res->headers->content_type.

=head2 $res->cookies

Returns a reference to a hash containing cookies to be set. The keys of the
hash are the cookies' names, and their corresponding values are hash
references used to construct a L<CGI::Cookie> object.

    $c->response->cookies->{foo} = { value => '123' };

The keys of the hash reference on the right correspond to the L<CGI::Cookie>
parameters of the same name, except they are used without a leading dash.
Possible parameters are:

=head2 value

=head2 expires

=head2 domain

=head2 path

=head2 secure

=head2 $res->header

Shortcut for $res->headers->header.

=head2 $res->headers

Returns an L<HTTP::Headers> object, which can be used to set headers.

    $c->response->headers->header( 'X-Catalyst' => $Catalyst::VERSION );

=head2 $res->output

Alias for $res->body.

=head2 $res->redirect( $url, $status )

Causes the response to redirect to the specified URL.

    $c->response->redirect( 'http://slashdot.org' );
    $c->response->redirect( 'http://slashdot.org', 307 );

=cut

sub redirect {
    my $self = shift;

    if (@_) {
        my $location = shift;
        my $status   = shift || 302;

        $self->location($location);
        $self->status($status);
    }

    return $self->location;
}

=head2 $res->status

Sets or returns the HTTP status.

    $c->response->status(404);
    
=head2 $res->write( $data )

Writes $data to the output stream.
