Are you just interested in fooling scanners? If so, then you can trap
outbound 404 html data with mod_security's output filter like this -
SecFilterSelective OUTOUT "The requested file you request does not exist"
status:200
You need to trigger on the html text of your 404 pages rather then HTTP
Status code line as the output filter does not capture that data. I believe
that Ivan is implementing a new directive to allow you to trap outbound
status codes.
Keep in mind, however that while this will change the status code to 200,
the html text that will be displayed will not of much help to real users wh=
o
have requested a non-existent page. For example, with my Apache setup this
is what is returned -
HTTP/1.1 200 OK
