I suspect that the problem you are going to run into implementing the
single ask for downloads location is the HTML security model. You, the
server, do NOT get to tell the client where to put the file, it will
either (possibly based on the user preferences) automatically place it
in a default download folder, or it may let the user have it ask for a
download location. The problem you are going to run into is that for a
give http request, I believe you can only supply a single file, so to
get multiple files download, it is going to require the use of
java-script, and since each file is a different "transaction", the
browser isn't going to normally let you link the destinations.
