Pb headers

[Nobody]

Hi,

On my page index.php (which is the default error page of my website), i
eventually show an error message which comes from the analysis of those
variables

// Code >>
$url_erreur = $_SERVER["REQUEST_URI"];
$serveur_erreur = $_SERVER["REDIRECT_STATUS"];
// << Code

On another page, i eventually redirect to my homepage if the parameters
are incorrect (this "another page" generate news and the output format
is in the parameters)

// Code >>
$mode = $_GET ["mode"];
if (($mode != "rss") && ($mode != "atom"))
{
// Redirect to index with error 404
header("HTTP/1.1 404 Not Found");
header("Location: http://localhost/me/");
}
// << Code

Problem : the error code 404 sent does not affect the server variables
and so there is no error message shown by index.php.

How could i do ?

TIA

PS : Please apologize my poor english ;-)

404 - there is no resource available for this URI.

> header("Location: http://localhost/me/");

Location means the resource exists, but is elsewhere, as indicated by the
absolute URL. (at least for 3xx responses anyway).

[url]http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.30[/url]

Surely a 4xx status and a Location header are mutually exclusive?

The Location response-header field is used to redirect the recipient
to a location other than the Request-URI for completion of the request
or identification of a new resource.

It is not said that the resource should exist. It is said "for
completion of the request or identification of a new resource". In my
opinion, it is correct to send a 404 error to indicate the resource
asked for does not exist, then to redirect the user elsewhere in order
to give him "a new resource" to look at, this resource explaining (via
an explicit message) the kind of problem encountered.

But my problem is not here. If i understood well, the 404 error
generated does not affect the server, it is simply sent to the client.
Opposite to the use of errorDocument.

So how sould i do to get the 404 code in my index.php ?
