[TYPO3-english] pageNotFound_handling does not throw 404 response code

[Sebastian Gebhard]

Hi *,

I have

$TYPO3_CONF_VARS['FE']['pageNotFound_handling'] = '/error/';
$TYPO3_CONF_VARS['FE']['pageNotFound_handling_statheader'] = 'HTTP/1.0 404 Not Found';
$TYPO3_CONF_VARS['SYS']['curlUse'] = '1';

Now when I type in www.eample.com/nonexistingpage I get a 302 to /error/ which returns 200.

My project is using TYPO3 4.2.10 and realurl 1.7

Any clues what could be wrong?
Mind that I do not want to read a static file from filesystem as 404, but I do want to show a actual 
TYPO3 page to display a sitemap, correct advertising, etc.

Did not help

Kind regards,
Sebastian
