推荐答案

无状态含义:

它不会跟踪下一个会话的配置设置，事务信息或任何其他数据.当程序不维护状态"(无状态)时，或者系统的基础结构阻止程序维护状态时，它将无法将有关上一个会话的信息带入下一个会话，例如用户选择的设置或在此期间出现的条件处理.

It does not keep track of configuration settings, transaction information or any other data for the next session. When a program "does not maintain state" (is stateless) or when the infrastructure of a system prevents a program from maintaining state, it cannot take information about the last session into the next, such as settings the user chose or conditions that arose during processing.

HTTP:

HTTP协议是Web事务的通信工具，它是无状态的.将网页交付给用户后，连接将关闭.已经开发出了对策，例如使用cookie，以维护用户在网站上从一个页面移到另一个页面的状态.

The HTTP protocol, which is the communications vehicle for Web transactions, is stateless. After a Web page is delivered to the user, the connection is closed. Counter measures, such as the use of cookies, have been developed to maintain the state of a user moving from page to page on a Web site.

或者它可以是简单的网络定义:

如果后续请求-响应对之间没有关系，则协议是无状态的.服务器可以唯一地处理每个请求，而不必为客户端保留会话状态.

A protocol is stateless if there is no relation between subsequent request-response pairs. The server can handle each request uniquely and does not have to keep a session state for the client.
