How can i set up httrack to search and get files from all directories
available? (we assume all folders are open for browsing and listing) 

Some  directories in between are only revealed after a file fetched from a
subdirectory, eg:

"website.com/link.html" 

transfers to this

"website.com/dir1/dir2/index.html"

we don't know the existence of "dir2" untill httrack grabs the index.html file
drom "dir2. 

How can we set httrack up so that it will search and grab any files from
"dir1" and others after those directories gets revelaed by the index file in
subdirectory "dir2" ?
