HTTP是无状态的，那么保持活着意味着什么呢？ [英] HTTP is statel-less,so what does it mean by keep-alive?

问题描述

Keep-Alive: 300
Proxy-Connection: keep-alive

正如我们所知，当请求得到响应时HTTP连接已关闭，那么 keep-alive 是什么意思，有人可以详细说明吗？

As we know HTTP connection is closed when the request gets responded,so what does it mean by keep-alive,can someone elaborate this?

推荐答案

这意味着可以保持连接打开以请求更多资源，例如图像和样式表。

This means it is OK to keep the connection open to ask for more resources like for example images and stylesheets.
