HEAD responses include body #278
Description
RFC 2616 section 9.4 states:
The HEAD method is identical to GET except that the server MUST NOT return a message-body in the response.
A HEAD request against this simple Rack app running on puma version 2.0.1:
require 'rack'
run lambda { |env| [200, {}, ['test']] }looks like this on the wire:
HEAD / HTTP/1.1
User-Agent: curl/7.24.0 (x86_64-apple-darwin12.0) libcurl/7.24.0 OpenSSL/0.9.8x zlib/1.2.5
Host: localhost:9292
Accept: */*
HTTP/1.1 200 OK
Transfer-Encoding: chunked

test

Even stranger, the body [''] looks like this:
HTTP/1.1 200 OK
Transfer-Encoding: chunked
0
0
And []:
