Since our scenario called for a form-based application (Microsoft Word) to take part in a request/response handshake, the communication between the initiator and the provider needed to be synchronous.
因为我们的情景需要基于表单的应用程序（Microsoft Word）参与请求／响应握手，所以启动者与提供者之间的通信必须是同步的。
Servers may also request connection renegotiation by sending an unsuccessful connect response with advice to reconnect with a handshake message.
服务端也可能要求连接重新协商，这要发送一个不成功的连接响应，并在握手消息中建议重连。
The exact requirements of how the connection should be opened, what should be sent in the opening handshake, and how the server's response should be interpreted are as follows in this section.
连接如何被打开、打开握手中应该发送什么、服务器端的响应如何去解读，在下面都会进行说明。
