It would really be nice to be able to have a CGI script generate
e.g. a FORBIDDEN message.
All I managed to produce so far is to send back some HTML document
that says forbidden but the server still tells OK.
When trying to implement e.g. proxy gateways via CGI scripts
this is really needed I think or otherwise we can't have a
transparent handling of the data.
Or is it already there and I didn't notice that?
