If depth < 1, the page won't be scanned at all, so this is 
not the good solution (and anyway, using depth is generally 
BAD, prefer to use Scan rules (filters))

K options are:
-K0 *relative link
-K absolute links
-K4 original links
-K3 absolute URI links

I suggest:

httrack www.yoururl.com -K -*

if you just want the first page.
