Re: err_headers_out vs headers_out

[Tofu Optimist]

Hmmm... I had read that thread; none of the postings
address setting anything beyond a cookie.
I'm looking for advice on something like this


sub cookie_and_redirect {
    my ( $r, $cookie, $dest ) = @_;

    $r->headers_out->set( Location => $dest );
    $r->headers_out->add( 'P3P' => P3P_CP );
    $r->headers_out->add(
        'Cache-Control' =>
'no-store,no-cache,must-revalidate' );
    $r->headers_out->add( 'Pragma' => 'no-cache' );

    $r->err_headers_out->add( 'Set-Cookie' => $cookie
);
    return &Apache::REDIRECT;
}

or, should it be like this

sub cookie_and_redirect {
    my ( $r, $cookie, $dest ) = @_;

    $r->headers_out->set( Location => $dest );
    $r->err_headers_out->add( 'P3P' => P3P_CP );
    $r->err_headers_out->add(
        'Cache-Control' =>
'no-store,no-cache,must-revalidate' );
    $r->err_headers_out->add( 'Pragma' => 'no-cache'
);

    $r->err_headers_out->add( 'Set-Cookie' => $cookie
);
    return &Apache::REDIRECT;
}

and more importantly, why?  I am interesting in
learning the difference between the two method calls.
As I still don't understand why in all the examples
given the Location param goes in a header_out, while
everything else goes in a err_header_out.


Many thanks
