Subject: [ruby-talk:19646] Threading a TCPServer

Hello!

I wrote the following little script:

require 'socket'

class NetJobsSession
  def initialize(connection)
    @connection=connection
  end
  def write(text)
    @connection.write text  
  end
  def send_http_header
    @connection.write "HTTP/1.1 200 OK\r\n"
    @connection.write "Content-Type: text/plain\r\n\r\n"
  end
  def close
    @connection.close
  end
end

class NetJobsServer
  def initialize(port)
    @listen=TCPServer.new('0.0.0.0', port)
  end
  def run
    loop{
      Thread.start(@listen.accept){ |aConnection|
	session=NetJobsSession.new(aConnection)      	
	session.send_http_header
	session.write "#{Time.now} #{Thread.current}"
	
	puts "#{Time.now} #{Thread.current}"
	
	sleep 5
	session.close
      }
    }
  end
end

server=NetJobsServer.new(4200)
server.run


If I let two browsers connect to this TCPServer I thought there would be
two threads started.
But what happens is, that when the first http-browsers connects to my
server a new thread is created,
but if (within the 5 seconds sleep time) a seccond browser connects to
the server two, there is
no new Thread started, but the second browser gets the same answer from
the server as the first one.
Is this a problem of my browsers? Is there something wrong with my
script? What can I do?

thanks and greetings
