turn off warning messages?

[H Garcia]

Hi list!

I'm trying to use EMPTY and ERROR tags into WEB tag, but I don't get the
expected results. I'm still getting the ugly message containing the password
of the user, which, I think, is a security problem.

I've tried with: 

MAP
 ...
 WEB
    ...
    ERROR error.html
    EMPTY empty.html
    LOG "C:/path_to_log/hidrocarburos.log"
     ...  
 END

...
END

and with 

    ERROR "http://localhost/mapserver/my_application/error.html"
    EMPTY "http://localhost/mapserver/my_application/empty.html"

but I still get the message "msDrawMap ...".

Must the html pages error.html and empty.html have a special format?

Thanks in advance!
