Is there a way to send a stream of output while processing, I want to
send ongoing status? The basic response construct seems to want the
output in a finalized form. The clients will render progressively from
what I understand.

Set an IO to res.body, and write data from another thread.

require "webrick"

class Streamlet < WEBrick::HTTPServlet::AbstractServlet
def do_GET(req, res)
res["content-type"] = "application/octet-stream"
r, w = IO.pipe
res.body = r
Thread.start{
10.times{|i|
w.write("#{i}" * 4096)
sleep(1)
}
w.close
}
end
end

httpd = WEBrick::HTTPServer.new(ort=>10080)
httpd.mount("/", Streamlet)
trap(:INT){ httpd.shutdown }
httpd.start
