I'm just curious -- does that filename work? I.e., if you access the
URL http://something.com/getfile?foo.bar, and you set the
Content-Disposition header, will the browser suggest foo.bar for the
filename? (Usually it would suggest getfile, I think)

Not easily. You could use JavaScript, and do
window.open(url_for_file) for each file. You'd end up with a bunch of
empty windows after you were done, though. Perhaps you could set an
event handler for those windows which would close it onLoad, and maybe
it would close the window after the user went through the Save
As... dialog, or maybe after they finished the download. It would
require lots of experimentation, as all JavaScript does, which is why
JavaScript is so annoying :)

See Chuck's comments. Just chunking it for .read() wouldn't be
enough, as Page also keeps the output contents in memory until your
finished unless you do streaming. I.e., self.write() doesn't (by
default) immediately write out to the adapter/web server/browser.
