Did you have any luck with this?  I have been trying to get 
this to work as well, but to no avail.  I use the --
catchurl option to get the URL to mirror, but when I run 
that in to httrack, it only mirror the screen saying "Sign 
in with your ID and password to continue."  Any help would 
be greatly appreciated, including perhaps how I can do this 
with another program if httrack just cannot do it.  Thanks 
a bunch.
