client.rb

require 'net/http/persistent'



url='http://127.0.0.1'
uri = URI  url

http = Net::HTTP::Persistent.new name: 'my_app_name'

# perform 10 times GET/POST

(1..10).each do |idx |
	response = http.request uri
        puts response.body
	# create a POST
	post_uri = uri + 'create'
	post = Net::HTTP::Post.new post_uri.path
	post.set_form_data 'some' => 'cool data'

	# perform the POST, the URI is always required
	response = http.request post_uri, post
	puts response.body
	sleep 3
end 


http.shutdown

client send requests (assume persistent) , server fork new thread to serve request and echo back thread.current to client
but ever request in 10 times echo different Thread.current that means fork different thread to serve next request

Server add headers 'Connection: Keep-Alive'
'net/http/persistent' recieve correct same Trhead .currrent

please close the issue
