PHP as ErrorDocuments (Apache)

I'm having a little trouble with using PHP scripts as ErrorDocuments, but I'm not sure where I'm slipping up. For example - I have the following in my .htaccess file: <Files "config.inc.php"> order deny,allow deny from all </Files> <Files "diary_admin.php"> AuthUserFile /home/ollie/htpasswd AuthGroupFile /dev/null AuthName "Diary Admin" AuthType Basic <Limit GET POST> require valid-user </Limit> </Files> ErrorDocument 401 /forbidden.php ErrorDocument 404 /missing.php If I go to http://site.com/non-existant then I get missing.php - which parses correctly - great! However, if I go to http://site.com/diary_admin.php I get forbidden.php, parsed correctly, before I'm even prompted for a username and password. Sometimes, however, it works. I tried clearing the cache etc. but that didn't seem to help. Can anyone see an obvious mistake that I'm making? For information: Server Version: Apache/1.3.12 (Unix) PHP/4.0.0 Ollie P.S. I'm aware that 401 is actually "Authorization Required" and that 403 is "Forbidden", but am just to lazy to rename the file! :) -------------------------------------------- Ollie Cook +44 (7946) 057 198 PGP: http://ollie.zenox.dhs.org/pgp-key --------------------------------------------
