Thank you Andrew.  Yes the server is truly returning 401.  I have already
reconfigured wget to download everything regardless of their timestamp,
but it's a waste of bandwidth, because most of the site is unchanged.

Do you know of any workaround in wget, or an alternative tool to ONLY
download newer files by http?
