EventMachine::MultiRequest

EventMachine based Multi request client, based on a streaming HTTPRequest class, which allows you to open multiple parallel connections and return only when all of them finish. (i.e. ideal for parallelizing workloads)

Example

EventMachine.run {

  multi = EventMachine::MultiRequest.new

  # add multiple requests to the multi-handler
  multi.add(:a, EventMachine::HttpRequest.new('http://www.google.com/').get)
  multi.add(:b, EventMachine::HttpRequest.new('http://www.yahoo.com/').get)

  multi.callback {
    p multi.responses[:callback]
    p multi.responses[:errback]

    EventMachine.stop
  }
}
