Using HTTrack 3.31:

httrack -gq 
<http://webphysics.davidson.edu/applets/classes/STools4.jar>

retrieves the file but saves it as "stools4.jar" while it 
reads STools4.jar at the server.

A work-around is options "-N %n.%t -Qb0c0q" instead of "-gq"

But then another strange feature:

A directory "hts-cache" is (dispite -Q) created if (and 
only if) the target directory already exists.
How can I suppress this? I want httrack (under some 
circumstances) to retrieve a bunch of files only.
