如何启用keep-alive？ [英] How can I enable keep-alive?

问题描述

我运行了一个Google Page Speed，它说我得分为 57/100 ，因为我需要启用Keep-Alive和启用压缩。我做了一些Google搜索，但我找不到任何东西。我甚至与我的域名提供商联系，要求他们打开它，但他们说它已经开始了。

推荐答案

Keep-alive为HTTP会话使用相同的tcp连接，而不是为每个新请求打开新的会话。您基本上需要在HTTP响应中设置HTTP标头

Keep-alive is using the same tcp connection for HTTP conversation instead of opening new one with each new request. You basically need to set HTTP header in your HTTP response

Connection: Keep-Alive
