A.7. Sending Cookies in REDIRECT Responses
You should use err_headers_out( ), not
headers_out(
), when you want to send
cookies in a REDIRECT response or in any other
non-2XX response. The difference between headers_out(
) and err_headers_out( ) is that the
latter prints even on error and persists across internal redirects
(so the headers printed for ErrorDocument handlers
will have them). Example A-3 shows a cookie being
sent in a REDIRECT.
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;
