[Mediawiki-l] 404 handling to shorten urls, header 200 OK doesn't work

[Sylvain Machefert]

Hi !

I've changed my "404 handling" to shorten my URLs.

If you call http://tousauxbalkans.jexiste.fr/Agenda the page displays in the
browser, but if I look the header, using a downloader (httrack,
nettransport...), I get this :

2006-07-14 14:13:30.296 HTTP Error

and the downloader doesn't continue because it receive a HTTP/1.1 404 Not
Found

My .htaccess simply contains the following instruction :
ErrorDocument 404 /404.php5

In 404.php5, I include index.php that's why the browser get the page.
Even if I set header 200 OK, it receive a 404 not found.

Here is my 404.php5 code :
<?php
header('HTTP/1.1 200 OK');
$title = substr(getenv('REQUEST_URI'), 1);
$title = str_replace('index.php?title=', '', $title);
$title = str_replace('index.php5?title=', '', $title);
$_GET['title'] = urldecode($title);
$_POST['title'] = urldecode($title);
$_REQUEST['title'] = urldecode($title);
include('index.php5');
?>

If I replace the include by a redirect, I receive a 302, a redirect to
index.php5 and then a 200.
header("Location: index.php5?title='.$title);

How do you explain in the first case I get a 404 error in 3 seconds, and in
the other case a 302 really quickly, whereas my .htaccess didn't changed,
and I never send header("HTTP/1.1 404 Not Found") in my code ?
