realurl multilanguage 404 page redirection

Question

I'm using a TYPO3 6.2 multilanguage installation and I want to redirect the user (using realurl extension) to a 404 page (created in the backend) in such way :

For en language (default) --> https://www.example.com/gfdg --> https://www.example.com/404

For de language --> https://www.example.com/de/gdfg --> https://www.example.com/de/404

Is it possible with $TYPO3_CONF_VARS['FE']['pageNotFound_handling'] ?

Answer 1

Yes, this is possible if you set $TYPO3_CONF_VARS['FE']['pageNotFound_handling'] in /typo3conf/AdditionalConfiguration.php, e.g. like here suggested: https://wiki.sebkln.de/doku.php?id=typo3:404

But Typo3 6.2 is outdated, so you should update to a recent Typo3-Version and use Typo3 Error Handling instead.
