I think you can still use ZipOutputStream though, it will only be<br>
blocking if the underlying Stream is blocking, so using something like<br>
a ByteArrayOutputStream would make the operation non blocking. If you<br>
want to avoid buffering the whole zip in memory you could potentially<br>
alternate between writing data to the ZipOutputStream and then taking<br>
anything written to the ByteArrayOutputStream and flushing it to the<br>
response channel.<br>
