Added information..

When I directly request the file from /index.php?sitemap=1 it does return a 200 status code. So it’s definitely in the way nginx handles the rewrite mentioned above..

Althoug not a specific plugin question, it is something more will run into.. Does anybody have any idea why the above rewrite (in combination with the nginx wordpress conf located on http://codex.wordpress.org/Nginx has such a side effect?

I’m not using any plugins, caches, other than this one.. :S
