[TYPO3-dev] Page 404 (500) error handler

[Thomas Petersen]

Hi.
Im new to the TYPO3 univers.
Can see that if i add this to localconf file, then i can make 2 pages (realURL) that can show me the Page 404(500) errors.

$TYPO3_CONF_VARS["FE"]["pageNotFound_handling"] = 'http://www.my-domain.com/not-found.html';
$TYPO3_CONF_VARS["FE"]["pageNotFound_handling_statheader"] = 'HTTP/1.1 404 Not Found';
$TYPO3_CONF_VARS["FE"]["pageNotAvailable_handling "] = 'http://www.my-domain.com/not-available.html';
$TYPO3_CONF_VARS["FE"]["pageNotAvailable_handling_statheader"] = 'HTTP/1.1 500 Not Available';

But i have the TYPO3 v.6 and here i can find the FE section like.
       'FE' => array(
		'loginSecurityLevel' => 'rsa',
	),

How do i add the TYPO3_CONF_VARS to the new localconf layout ?
