How do I use the Rack handler?

[rkh]

rackup -s HTTP doesn't work (I think rack is trying to load rack/handler/hTTP.rb), neither does rackup -s http, as you don't call register in the handler.

Hmm rackup -s HTTP works for me (net-http-server 0.2.1). Although, it's returning Chunked Transfer-Encoding lines.

Isn't Transfer-Encoding a response header?

Here's what I'm seeing with net-http-server 0.2.1 and rack 1.4.1:

run lambda { |env|
  [200, {'Content-Type' => 'text/html'}, ['hello world']]
}

$ rackup -s HTTP
$ curl -v http://localhost:9292/
* About to connect() to localhost port 9292 (#0)
*   Trying 127.0.0.1... connected
* Connected to localhost (127.0.0.1) port 9292 (#0)

b

Ah it appears Rack is doing it's own Chunked Encoding:
