The browser listens for the content type of the file you are downloading in
order to decide what to do with it. You can determine the content type to
send by calling
getServletContext().getMimeType(itemName); // itemName is the filename
of the file to be downloaded
and use this to replace the "application/x-zip-compressed" string constant.
