I use httrack unnattended to download a number of sites, 
and I'd like it to update the httrack cache if it is 
available (ie I have downloaded the site before) or 
download from scratch automatically if not. The default 
behaviour is to prompt the user if there is an existing 
cache, which obvious stops the download until I respond. 
Any way to over-ride this and just go ahead?
Many thanks
Stevod
