Subject How to return HTTP error codes using hook filter ...
Date Wed, 12 Mar 2008 19:53:30 GMT

details, and return HTTP_BAD_REQUEST; /* 400 */

However, apache will respond with the default HTTP_BAD_REQUEST message
text and ignore the changes I make calling the ap_set_content_type() and
ap_rprintf() routines.

Unless I return 0 then it works fine, except the result is 200 OK when
it should be 400 Bad request.

How can I change the body and indicate the error code which should be
