It does, but only in content generators.  You are working in a content
filter, which occurs after any content-generator should have run
(including the error generator itself).  I expect that your only
solution is to generate your own error page, however, I am not any kind
of an expert in this niche you are asking about.

It should be done using the content generator.  If an output filter runs
and fails, the user really shouldn't end up with an entire 404.  That
should only really occur if the actual document wasn't found.  But
again, that is my opinion.  Take it for what it is worth.
