[TYPO3] 404 error page redirection

[Klaus Hinum]

hi group,

i know that this topic has been discussed before and i read that it 
should be fixed with 4.0 but i still have the problem, that i can't get 
typo3 to redirect 404 errors to a specific page AND return a 404. i can 
do either the one (standard error with 404) or redirect (returns 200 and 
before the number for the redirect).

do i have to use the extension?

fyi, i use simulated static documents.

thanks in advance
klaus
