=head1 NAME
-Catalyst::Response - Catalyst Response Class
+Catalyst::Response - stores output responding to the current client request
=head1 SYNOPSIS
$res = $c->response;
$res->body;
+ $res->code;
$res->content_encoding;
$res->content_length;
$res->content_type;
$res->status;
$res->write;
-See also L<Catalyst::Application>.
-
=head1 DESCRIPTION
-This is the Catalyst Response class, which provides a set of accessors
-to response data.
+This is the Catalyst Response class, which provides methods for responding to
+the current client request. The appropriate L<Catalyst::Engine> for your environment
+will turn the Catalyst::Response into a HTTP Response and return it to the client.
=head1 METHODS
-=over 4
-
-=item $res->body($text)
+=head2 $res->body(<$text|$fh|$iohandle_object)
$c->response->body('Catalyst rocks!');
-Contains the final output.
+Sets or returns the output (text or binary data). If you are returning a large body,
+you might want to use a L<IO::Handle> type of object (Something that implements the read method
+in the same fashion), or a filehandle GLOB. Catalyst
+will write it piece by piece into the response.
+
+=head2 $res->has_body
+
+Predicate which returns true when a body has been set.
+
+=head2 $res->code
+
+Alias for $res->status.
-=item $res->content_encoding
+=head2 $res->content_encoding
-Shortcut to $res->headers->content_encoding
+Shortcut for $res->headers->content_encoding.
-=item $res->content_length
+=head2 $res->content_length
-Shortcut to $res->headers->content_length
+Shortcut for $res->headers->content_length.
-=item $res->content_type
+=head2 $res->content_type
-Shortcut to $res->headers->content_type
+Shortcut for $res->headers->content_type.
-=item $res->cookies
+This value is typically set by your view or plugin. For example,
+L<Catalyst::Plugin::Static::Simple> will guess the mime type based on the file
+it found, while L<Catalyst::View::TT> defaults to C<text/html>.
-Returns a reference to a hash containing the cookies to be set.
+=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' };
-=item $res->header
+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:
+
+=over
+
+=item value
+
+=item expires
+
+=item domain
+
+=item path
+
+=item secure
+
+=back
+
+=head2 $res->header
-Shortcut to $res->headers->header
+Shortcut for $res->headers->header.
-=item $res->headers
+=head2 $res->headers
-Returns a L<HTTP::Headers> object containing the headers.
+Returns an L<HTTP::Headers> object, which can be used to set headers.
$c->response->headers->header( 'X-Catalyst' => $Catalyst::VERSION );
-=item $res->output
+=head2 $res->output
-Shortcut to $res->body
+Alias for $res->body.
-=item $res->redirect( $url, $status )
+=head2 $res->redirect( $url, $status )
-Contains a location to redirect to.
+Causes the response to redirect to the specified URL. The default status is
+C<302>.
$c->response->redirect( 'http://slashdot.org' );
$c->response->redirect( 'http://slashdot.org', 307 );
+This is a convenience method that sets the Location header to the
+redirect destination, and then sets the response status. You will
+want to C< return; > or C< $c->detach() > to interrupt the normal
+processing flow if you want the redirect to occur straight away.
+
=cut
sub redirect {
return $self->location;
}
-=item $res->status
+=head2 $res->location
+
+Sets or returns the HTTP 'Location'.
+
+=head2 $res->status
-Contains the HTTP status.
+Sets or returns the HTTP status.
$c->response->status(404);
+
+$res->code is an alias for this, to match HTTP::Response->code.
-=item $res->write( $data )
+=head2 $res->write( $data )
Writes $data to the output stream.
+=head2 meta
+
+Provided by Moose
+
+=head2 $res->print( @data )
+
+Prints @data to the output stream, separated by $,. This lets you pass
+the response object to functions that want to write to an L<IO::Handle>.
