while the old ones should not get updated. I succeeded to do this by deleting
hts-cache (or alternatively applying --purge-old=0) and then httracking
exclusively the new address into the same output folder.

Are you making a new project for each site, or are they all thrown into one
project?
I should think that you would want one project per site - then you can update
only the sites you choose to.  The other projects won't be updated but will
still appear in the index.
