我正在努力提高页面速度,建议让Connection:Keep-alive。然而,无论我尝试做什么,我都有"保持活力,关闭"。我无法找到"关闭"价值来自。
我也不能删除它。有人经历过同样的事情吗?
我的.htaccess中有这个:
标题集连接保持活动状态
祝你好运, 拉斯穆斯

您的服务器似乎已禁用您的帐户或整个服务器的保持活动状态,以确保Rasmus始终可以使用最大套接字数。
这当然是一把双刃剑,因为大多数网站在提取构建页面所需的所有资源时通常会产生10-30个请求,而不会缓存任何内容,这会产生大量的开放和结束开销。即使它需要下载50个额外的资源,设置如下:
<ifModule mod_headers.c>
Header set Connection keep-alive
Keep-Alive: timeout=5, max=100
</ifModule>
将有足够的时间来完成工作。但我确定禁用此功能的标准做法是确保它不会被滥用。只要问你的管理员他们是否可以帮你。
我的建议是不要担心Keep-Alive标题,无论如何都要确保正确缓存静态文件,这样你就可以获得更多好处。如果您的管理员为您提供了很好的帮助,但这就是我在.htaccess文件中添加的内容,以帮助将收到的请求数量减少60%-80%。
