Forklaringen springer jeg over, men her er et l�sningsforslag :-)

.htaccess:

ErrorDocument 404 /redirect.php

redirects.txt:

/mappe1/filnavn.htm http://mitdom�ne/mappe1/mappe2/filnavn.php
/mappe1/filnavn2.htm http://mitdom�ne/mappe1/mappe2/filnavn2.php

redirect.php:

<?php
$redirects = "redirects.txt";
$redirect_url = $_SERVER['REDIRECT_URL'];
$handle = @fopen($redirects, "r");
if ($handle) {
     while (($line = fgets($handle, 4096)) !== false) {
         list($oldUrl, $newUrl) = explode(" ", $line);
         if($redirect_url == $oldUrl) {
             header("Location: $newUrl", true, 301);
             exit;
         }
     }
     if (!feof($handle)) {
         echo "Error: unexpected fgets() fail\n";
     }
     fclose($handle);
}
header('Content-Type:text/html; charset=UTF-8', true, 404);
?>
<html>
    <head>
       <body>
          Dette er din 404 side
       </body>
    </head>
</html>

Ideen er den at redirect.php fungerer som 404 fejlside. Den kigger s� p� 
den forespurgte url (REDIRECT_URL) og indl�ser s� din redirects.txt og 
kigger efter et match.

Er der et match, hopper den til den nye url med en 301 kode.

Findes der ikke noget match, forts�tter filen sin videre f�rd og 
udsender en 404 kode sammen med det indhold du v�lger der skal st� p� 
din fejlside.

P� den m�de f�r du alts� to fluer med et sm�k, dels dine redirects, dels 
en custom fejlside :)

Du skal naturligvis pille lidt ved url'erne s� de passer til din server. 
Det er vigtigt at fejlsiden i .htaccess starter med en slash, alts� en 
relativ sti fra webroden.
