* ruby -v: ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-darwin16]

----------------------------------------
I tried to use drb over http with the sample code *sample/drb/http0*.rb*
I wrote the code as following.

*server.rb*
~~~
require 'drb/drb'
require_relative './http0serv'

class SampleObject
  def test
    "ACK!"
  end
end

DRb.start_service("http://127.0.0.1:1234", SampleObject.new)
DRb.thread.join
~~~

*client.rb*
~~~
require 'drb/drb'
require_relative './http0'

remote = DRbObject.new_with_uri "http://127.0.0.1:1234"

puts remote.test
~~~

This results in the following.
