[undertow-dev] Async sending of NIO objects thru a ServletOutputStream?

[Jim Crossley]

I actually figured that out, Stuart, thanks. So I have writing a ByteBuffer
covered. Any thoughts on handling the ReadableByteChannel?  Looking at the
Jetty impl, it appears I need to read it into one or more ByteBuffers and
then write them out. Should I use the Pooled<ByteBuffer> from the exhange's
connection?
