Downloading a file generated on the fly
string target already does the streams.copy thing in its respond so
you can just dorespond() { ... r.setattachmentheader(..);
r.setContentType(..) super.respond(); }or do how i showed you in the
first place using an anonymous imple of IRequestTarget directly.
IRequestTarget.detach() { } IRequestTarget.getLock() { return null;
