Apache:如何在未安装mod_expires的文件中添加Expires标头 [英] Apache: How to add Expires headers to files without mod_expires installed

问题描述

我在运行Apache的共享主机上.显然未安装mod_expires. 在该环境中，还有另一种方法可以将过期标题添加到css文件，图像等吗?

I'm on a shared host running Apache. Apparently mod_expires is not installed. Is there another way to add expires headers to css-files, images etc. on that environment?

推荐答案

在您的.htaccess中(如果可以的话)，您可以使用 Header指令.不过，这需要mod_headers，而且我很确定您不能指定滚动"到期日期(即从现在开始一年").因此，您需要编辑此设置，例如，每年一次 ¹ .

In your .htaccess (if that's an option) you can use a <FilesMatch> block with Header directives. This requires mod_headers, though, and I'm pretty sure that you can't specify a "rolling" expiration date (i.e., "one year from now"). Therefore, you'll need to edit this setting, say, once a year¹.

另外，您是否看到此问题?

¹⁾显然，您应该避免将Expires设置为超过一年的时间:请勿将其[Expires标头]设置为多个违反了RFC准则."(来源:

¹⁾ Apparently you should refrain from setting the Expires to more than a year into the future: "Do not set it [the Expires header] to more than one year in the future, as that violates the RFC guidelines." (source: Optimize caching)
