    • In one aspect, method for bidirectional asynchronous data communication between a client and a server over the Internet via a hypertext transfer protocol based on a request/response paradigm is provided. With the aid of a single communication channel, a communication sequence is initiated by the client, such that the two partners are able to exchange data asynchronously and bidirectionally. After the client has established the connection via a request the client sends data to the server as a further request, while the server sends data to the client as a response to the last request. If the server has no data to send, then after a timeout time it sends a dummy response in order to keep the channel open. If the server receives a new request, then it terminates the old one and sends any data remaining to be sent as a response to the new request.
    • 在一个方面,提供了一种通过基于请求/响应范例的超文本传输​​协议通过因特网在客户端和服务器之间进行双向异步数据通信的方法。 借助于单个通信信道,由客户端启动通信序列,使得两个伙伴能够异步地和双向交换数据。 在客户端通过请求建立连接之后,客户端作为进一步的请求将数据发送到服务器,而服务器作为对最后一个请求的响应将数据发送到客户端。 如果服务器没有要发送的数据,则在超时之后,它发送一个虚拟响应,以保持通道的打开状态。 如果服务器接收到新的请求,那么它将终止旧的请求,并发送剩余的要发送的数据作为对新请求的响应。
