My searches have turned up blank... I'm trying to change the 403 Forbidden status of the response to a 404 Not Found status with this line:
Header set Status-Line "HTTP/1.1 404" "expr=%{REQUEST_STATUS} == 403"
However, this is having no effect. I suspect it might be because there actually isn't a Status-Line header used by Apache, although it is part of the HTTP spec. So is this even possible? I'm trying to get this done with a Header directive rather than rewriting, as it seems the better way to do it.
