httrack may not transfer the creditentials? A possible 
reason: if these links are absolute (http://), httrak will 
not send creditentials unless the host/directory 
arerecognized.

If the starting URL was:
<http://smith:foo@www.example.com/bar/whatever/foo/>
and the link points to:
<http://www.example.com/foo/>

then, httrack won't pass the username/password.

The only hack to bypass this limit is to add a second fake 
URL in httrack:
<http://smith:foo@www.example.com/foo/invalid>

In this case, httrack should send creditentials when seeing 
<http://www.example.com/foo/>
