In the IIS settings for a virtual server or directory you can associate a
page to a custom error message like a 301. You would need to have direct
access to the IIS box to do this, or a host that will point the custom error
messages to a file that you define. The htaccess method only works for
UNIX/Linux servers as IIS uses it's own metabase to store this information
in.
Hope this helps,
