 =head1 NAME
 
-Catalyst::Response - Catalyst Response Class
+Catalyst::Response - stores output responding to the current client request
 
 =head1 SYNOPSIS
 
-See L<Catalyst::Application>.
+    $res = $c->response;
+    $res->body;
+    $res->code;
+    $res->content_encoding;
+    $res->content_length;
+    $res->content_type;
+    $res->cookies;
+    $res->header;
+    $res->headers;
+    $res->output;
+    $res->redirect;
+    $res->status;
+    $res->write;
 
 =head1 DESCRIPTION
 
-The Catalyst Response.
+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
+
+=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<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
+
+Shortcut for $res->headers->content_encoding.
+
+=head2 $res->content_length
+
+Shortcut for $res->headers->content_length.
 
-=head2 METHODS
+=head2 $res->content_type
 
-=head3 cookies
+Shortcut for $res->headers->content_type.
 
-Returns a hashref containing the 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>.
+
+=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::Simple::Cookie> object.
 
     $c->response->cookies->{foo} = { value => '123' };
 
-=head3 headers
+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:
+
+=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 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 );
 
-=head3 output
+=head2 $res->output
 
-Contains the final output.
+Alias for $res->body.
 
-    $c->response->output('Catalyst rockz!');
+=head2 $res->redirect( $url, $status )
 
-=head3 redirect
+Causes the response to redirect to the specified URL. The default status is
+C<302>.
 
-Contains a location to redirect to.
+    $c->response->redirect( 'http://slashdot.org' );
+    $c->response->redirect( 'http://slashdot.org', 307 );
 
-    $c->response->redirect('http://slashdot.org');
+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.
 
-=head3 status
+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.
 
-Contains the HTTP status.
+=cut
+
+sub redirect {
+    my $self = shift;
+
+    if (@_) {
+        my $location = shift;
+        my $status   = shift || 302;
+
+        $self->location($location);
+        $self->status($status);
+    }
+
+    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);
 
-=head1 AUTHOR
+$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
+the response object to functions that want to write to an L<IO::Handle>.
 
-Sebastian Riedel, C<sri@cpan.org>
+=head2 DEMOLISH
+
+Ensures that the response is flushed and closed at the end of the
+request.
