=head1 NAME
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
+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->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>.

+Writes headers to response if not already written

+Ensures that the response is flushed and closed at the end of the
