Thanks. I did that, but then had to also use the error_page directive to point it at my 404.php page.

However this has the undesirable effect of then changing the URL in the browser to 404.php.

Is there a way I can have nginx return the content of my 404.php page as the output, so the user still sees their bad page in the URL (i.e. http://www.mysite.com/badpage.php instead of http://www.mysite.com/404.php)?

Thank you.
