The appropriate L for your environment +will turn the Catalyst::Response into a HTTP Response and return it to the client. + +=head1 METHODS + +=head2 $res->body( $text | $fh | $iohandle_object ) + + $c->response->body('Catalyst rocks!'); + +Sets or returns the output (text or binary data). If you are returning a large body, +you might want to use a L 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 + +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. + +This value is typically set by your view or plugin. For example, +L will guess the mime type based on the file +it found, while L defaults to C. + +=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 object. + + $c->response->cookies->{foo} = { value => '123' }; + +The keys of the hash reference on the right correspond to the L +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 + +=item httponly + +=back + +=head2 $res->header + +Shortcut for $res->headers->header. + +=head2 $res->headers + +Returns an L 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. 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.
