How to return 404 for unknown page

[getsimplethemes]

My installation is not returning a 404 for an unknown-page request. Instead, it displays a "Oops Page not found" message. I like that, but I'd also like the server to return 404 as well. Currently it is returning 200.

I tried the bug fix mentioned here ( http://code.google.com/p/get-simple-cms/...tail?r=194 ) but the server still returned a 200.

I'm using GS 2.03 plus that patch mentioned above. I use a modified .htaccess (I run other apps as well as GS on the site) but I'm not rewriting the headers as far as I can tell.

I wonder if this is doing it

Code:

RewriteRule /?([A-Za-z0-9-]+)/?$ index.php?id=$1 [QSA,L]

An example is (/fathead is non-existent):

Code:

(in browser) http://www.nickcoleman.org/fathead
(from apache log)  "GET /fathead HTTP/1.1" 200 2284 "-"

Thanks.

Could you post a link to your site?
