感谢Vader精彩的回复,我自己也总结了一下:
Stateless refers to an architecture where each HTTP request is fundamentally detached from requests that came before, and unrelated to requests that will follow.That is to say,each request-respond pair is dicrete,no stateful information stored for it to evoke/retrieve early memories/context.
引用:
例如client的每一个请求和Server的每一个回复甚至都会标明自己支持的HTTP协议版本号,完全假设之前Client和Server之间的通讯是没有的
用一个词来总结,就是
independent
对于和HTTP同处于一个层的FTP来说,则是通过control/command connection(tcp port 32)来实现stateful session,而http则是一个stateless session
