 =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.

-=item $res->body($text)

     $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.

+Shortcut for $res->headers->content_type.
 
-Shortcut to $res->headers->content_type
+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>.
 
-=item $res->cookies
+=head2 $res->cookies
 
-Returns a reference to a hash containing the cookies to be set.
+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

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

-Shortcut to $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.
