protocols - 与无状态协议(protocol)相反？

Question

我想知道“无状态协议(protocol)”的反面是什么。例如，鉴于 HTTP 是无状态的，那么像 FTP 这样的协议(protocol)是相反的/维护状态的协议(protocol)，我的假设是否正确？

谢谢。

Answer 1

有无状态协议(protocol)(如 http)和有状态协议(protocol)(如 ftp、telnet...)。

根据wikipedia :

In computing, a stateless protocol is a communications protocol that treats each request as an independent transaction that is unrelated to any previous request so that the communication consists of independent pairs of requests and responses. A stateless protocol does not require the server to retain session information or status about each communications partner for the duration of multiple requests.

根据这个article - 有状态协议(protocol):

The client connects to the server, conducts a series of operations via that conneciton, and then disconnects.Then server can associate all of the requests together and knows that thy all came from the same user.
