    By design due to how it is configured.

    A customer have a IIS 6 web server and even with IIS Write property
    DISABLED,
    an ASPX form can upload files to the server.
    The authentication is Anon (via IUSR_ user) and the IUSR_User have RWXD
    rights on the folder where the upload  is stored.
    In the properties of the IIS folder where upload is done, the Read
    permission is set, but Write, SourceAccerss and Browse are disabled.
    Why the upload works???
