One thing you could try would be to change the way you create URLs for downloadable
files:
<html>
<head><title>Page Title</title></head>
<body>
<a href="/servlets/download/file1.zip">File 1</a>
</body>
</html>
Note that there is a slash before the filename instead of a question mark.
Now, assuming that your download servlet is mapped to "/servlets/download", you can
retrieve the name of the requested file like this:
String str_Filename = request.getPathInfo();
which will return "/file1.zip" in the case above. You can get rid of the leading
slash if you don't want it.
Doing things this way avoids the fact that browsers are inconsistent and/or buggy
in how they handle the content disposition header, but they default to what looks
(to them) like the last component of the request URL -- so the prompt would be to
save "file1.zip" in this case.
