=head1 DESCRIPTION
This is the Catalyst Response class, which provides methods for responding to
-the current client request.
+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
-=head2 $res->body($text)
+=head2 $res->body( $text | $fh | $iohandle_object )
$c->response->body('Catalyst rocks!');
-Sets or returns the output (text or binary data).
+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.
=head2 $res->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.
+references used to construct a L<CGI::Simple::Cookie> object.
$c->response->cookies->{foo} = { value => '123' };
-The keys of the hash reference on the right correspond to the L<CGI::Cookie>
+The keys of the hash reference on the right correspond to the L<CGI::Simple::Cookie>
parameters of the same name, except they are used without a leading dash.
Possible parameters are:

-=head2 domain

-=head2 path

-=head2 secure

=head2 $res->header
=head2 $res->redirect( $url, $status )
-Causes the response to redirect to the specified URL.
+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.
+
+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.

sub redirect {
return $self->location;
}
+=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 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>.
