php - 如何使用 php 覆盖 Apache keep-alive header ？

Question

在我的 httpd.conf 中有:

KeepAliveTimeout 1

我试图在单个 php 脚本(而不是整个服务器)中覆盖 Apache KeepAliveTimeout 设置，所以我有一个 php 脚本:

header("Keep-Alive: timeout=60, max=100"); 

不过好像没什么区别。我仍然得到回应:

Keep-Alive:timeout=1, max=50

有什么解决办法吗？

你不能那样做。它在那里是有正当理由的。

Apache v2.2 Core Features

KeepAliveTimeout 指令

The number of seconds Apache will wait for a subsequent request before closing the connection. Once a request has been received, the timeout value specified by the Timeout directive applies.

Setting KeepAliveTimeout to a high value may cause performance problems in heavily loaded servers. The higher the timeout, the more server processes will be kept occupied waiting on connections with idle clients.
