How can you redirect ALL 404 pages on a server to a single php file?

[vaxop]

I have like 40 domains on a server and Id like all 404 pages (including all subdomains) to be redirected to a single php file (passing the requested URL to the script)

Anyone know how to do this?

I guess it can be done with http.conf found under /etc/httpd/conf/http.conf

ErrorDocument 404 /404.php

so that it will be implemented throughout the server

thanks :)
also, how can i pass the URL that was requested to the php file?

It should be available in a server variable -- REQUEST_URI is what it's called at the server level, and PHP's name for it will be similar.

the varname in php is exactly the same $_SERVER['REQUEST_URI']

[php.net...]

ah
but how would I be able to tell the domain that was requested?
wont URI just give the file?

Check HTTP_HOST -- and any others you might want or need. :)
