+Alias for $res->status.

=head2 $res->content_encoding
Shortcut for $res->headers->content_encoding.
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->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.
+
+B<Note:> do not give a relative URL as $url, i.e: one that is not fully
+qualified (= C<http://...>, etc.) or that starts with a slash
+(= C</path/here>). While it may work, it is not guaranteed to do the right
+thing and is not a standard behaviour. You may opt to use uri_for() or
+uri_for_action() instead.

+=head2 $res->location
+
+Sets or returns the HTTP 'Location'.
+
=head2 $res->status
Sets or returns the HTTP status.
$c->response->status(404);
-
+
+$res->code is an alias for this, to match HTTP::Response->code.
+
=head2 $res->write( $data )
Writes $data to the output stream.
+=head2 $res->print( @data )
+
+Prints @data to the output stream, separated by $,. This lets you pass

+
+=head2 $self->finalize_headers($c)
+
+Writes headers to response if not already written
+
+=head2 DEMOLISH
+
+Ensures that the response is flushed and closed at the end of the
+request.
