Thanks for your answer.

Setting "URLhack" off with a mirroring >1 does indeed fix the redirection
issue (using http://), but it sends httrack on an endless loop when capturing
the site. I had to interrupt httrack after 1h...or so. The log was showing
tons of warnings as such this one:
"17:50:38 Warning:  engine: unexpected duplicate file entry: ..."

(capturing the site using https:// and the hack on, takes about 2 minutes and
works perfectly)

Question # 1: Any idea ? What does the option "URL hack" do exactly?Question #
2: Incidentally, how do I programatically test for this error when running
from the console?  i.e: 'mirror ERROR', is there a file, a flag, etc...to test
on. I.e: How do I know httrack failed ?
Note: When depth =1 even with the URL hack flag off, I have the redirection
problem when running against http:// instead of https://.

Thank you,
