IIRC, DownloadLink and Igor's anonymous class will lock the session, so if
you have one downloading over a very slow connection, other users will get a
timeout.
Cheers,

I guess I forgot to mentionthe single most important aspect of my question:
The archive not present on the file system, it is dynamically
assembled on the fly from individual files.
(the whole point is downloading multiple files in one go.)

Hi there,
The downside of an easy-to-use framework is the influx of users with
little understanding of the underlying servlet technology, like me.
Observe:
I'd like to provide a ZIP file (could be TAR, anything Windows PCs can
save and later extract from) as a download, one that is potentially
too big to be kept in memory in full.
So I guess I'd need to "stream" it in chunks, or as a java stream or
channel.
Can I do that from wicket?
Or does the servlet interface require a fully assembled response in
memory?
Currently I assemble the ZIP file in a byte array in full, but it
feels awkward. Would extending WebResource fit the bill?
ByteArrayOutputStream bout = new
ByteArrayOutputStream();
ZipOutputStream zout = new ZipOutputStream(bout);
// Add entries
zout.finish();
zout.close();
Resource resource = new
ByteArrayResource("application/zip",
bout.toByteArray());
ResourceStreamRequestTarget target = new
ResourceStreamRequestTarget(resource.getResourceStream());
target.setFileName(new
SimpleDateFormat("yyyyMMddHHmmss").format(Calendar.getInstance
().getTime())
+ ".zip");
getRequestCycle().setRequestTarget(target);
All suggestions are welcome.
