Are you wanting some access to the listing or no access to be seen from the web ??
Maybe someone else knows of another way.. if you don't want any access, best bet is probably the redirect command..
there are other methods like using the mod_block.c or a another URL rewriter is the mod_uri_remap.c instead of the mod_rewrite in which i forgot about in my previous post..
so your best options are basically the
Redirect, Alias and Rewrite commands.. you can find more info most likely at www.apache.org
