Scratch another its - this patchs allows me to hugely simply auth modules

which use non 4xx methods for auth (such as cookies, referers ,etc).

Submitted by Sander van Zoest (for a slightly different reason) - see
explanation below.

From: Sander van Zoest
To: dev@httpd.apache.org

It is common practice to set Cookie's to pass along on HTTP
redirects for "login" authentication.

When implementing P3P <http://www.w3.org/P3P/> using
mod_headers.c the Header directive only sets r->headers_out
and does not pass the headers along for non-2XX responses
such as error pages and redirects.

To provide this functionality we added the ErrorHeader
directive which populates r->err_headers_out instead.

Below follows a patch for 1.3.X by Michael Radwin <radwin_at_yahoo-inc.com>.

I have some code that attempts to add Directive to 2.0.X, but
it seems that output_filters are shortcuted on 3XX responses.
While now by setting the Header directive it also passes the headers
along at for all non-2XX responses except 3XX responses.

Cheers,
