谁帮我看看故障出在哪里。

原先网上找的源码。做端口转发的。
测试正常。现在想要改一下。

改成 端口收到内容后发往两台服务器（原先代码是一台），并且把服务器返回的内容再传给客户端。
按上面改了之后，只能发给第一个服务器，不能发给第二个。是不是要加个变量存储中转一下。

请会的同学看一下，帮忙改改。

      log('new connect')
      # two direct pipe
      PipeThread(target_fd, client_fd).start()
      PipeThread(target_fd1, client_fd).start()
      PipeThread(client_fd, target_fd).start()

改成

      log('new connect')
      # two direct pipe
      PipeThread(target_fd, client_fd).start()
      PipeThread(target_fd1, client_fd).start()
      PipeThread(client_fd, target_fd).start()
      PipeThread(client_fd, target_fd1).start()

这样才对称吧？
