Hi William,

Thank you for your response.  Forgive me for being dense ... :\ ...

1) My apologies for incorrectly using the term "back up" ... you're right,
what I'd like is a snapshot of my password'd Google Site.  If I cron the
snapshot once a day, at most, I lose the day's worth.  I rsync my home
directory and keep seven day's worth of backups - sliding window.

2) FWIW, I'm on Linux and I'm not using the GUI.  I did use --captch-url and
as I mentioned, I received the same captured URL as Paolo: 
<http://www.google.com:443?>postfile:hts-post0">>;;  ... or similar ..

3) Since HTT will not capture https, does this mean that HTT cannot be used in
an automated set up to snapshot a Google Site which requires authentication?
4) I'll definitely post the example I used if it's useful for this situation
... it seems, and perhaps I'm misreading your post, that HTT won't work in an
automated set up to snapshot a Google Site which requires authentication.  

Thank again for your response.
