Yes, filesave2 (see <http://httrack.com/html/plug.html>) is probably the good
candidate. However, httrack will save _anyway_ the file in the target
directory (there is no way to tell httrack NOT to actually save the file) ;
but you can choose a regular directory as target, and use your shadow-copy
directory in your module.

(Plenty of examples are available in libtest/)

By the way, what is the purpose of using shadow-copy when saving a mirror ?
