Why?
Appendix A.7 from the Stas' Practical mod_perl book states:
> You should use err_headers_out( ), not headers_out( ),

And gives the following recipe:
Example A-3. redirect_cookie.pl
use Apache::Constants qw(REDIRECT OK);
my $r = shift;
# prepare the cookie in $cookie
$r->err_headers_out->add('Set-Cookie' => $cookie);
$r->headers_out->set(Location => $location);
$r->status(REDIRECT);
$r->send_http_header;
return OK;
How would you have written it?

Why is that?
