Thanks for your help, but it still not working.  If I 
Point HTTrack to 
<http://cungviet.org/thanhnhaconline/> instead
HTTrack will download the whole site with out the 
inaccessable folder.  All I want is to download 
everything in the inaccessable folder, and I know that 
this folder is located in <http://cungviet.org>.  And 
the address to this folder is 
<http://cungviet.org/inaccessable>.  The thing is that 
they have redirection page in that folder so I can not 
download it.  Please help.
