希望疗法是在documenattion自己的网站 –

谷歌'PHP添加过期headers' –

我假设'static.doers。 lk'是你自己的网站？ –

添加这些标头的最简单方法是向您的服务器添加一些配置的.htaccess文件。如果资产托管在您无法控制的服务器上，则无法对此进行任何操作。

请注意，某些托管服务提供商不会让您使用.htaccess文件，因此请检查他们的条款是否似乎无效。

该HTML5Boilerplate项目有一个很好的.htaccess文件，涵盖了必要的设置。请参阅文件中的相关部分在其Github repository

这些都是重要的位

# ---------------------------------------------------------------------- 
# Expires headers (for better cache control) 
# ---------------------------------------------------------------------- 

# These are pretty far-future expires headers. 
# They assume you control versioning with filename-based cache busting 
# Additionally, consider that outdated proxies may miscache 
# www.stevesouders.com/blog/2008/08/23/revving-filenames-dont-use-querystring/ 

# If you don't use filenames to version, lower the CSS and JS to something like 
# "access plus 1 week". 

<IfModule mod_expires.c> 
    ExpiresActive on 

# Your document html 
    ExpiresByType text/html "access plus 0 seconds" 

# Media: images, video, audio 
    ExpiresByType audio/ogg "access plus 1 month" 
    ExpiresByType image/gif "access plus 1 month" 
    ExpiresByType image/jpeg "access plus 1 month" 
    ExpiresByType image/png "access plus 1 month" 
    ExpiresByType video/mp4 "access plus 1 month" 
    ExpiresByType video/ogg "access plus 1 month" 
    ExpiresByType video/webm "access plus 1 month" 

# CSS and JavaScript 
    ExpiresByType application/javascript "access plus 1 year" 
    ExpiresByType text/css "access plus 1 year" 
</IfModule>

他们有documented what that file does，最重要的一点是，你需要重命名你的CSS和JavaScript文件时，他们改变，因为一旦他们被缓存，访问者的浏览器将不会再检查一年。

我想在github中添加完整的代码到htaccess – sami

不，只是“Expires标题”部分。甚至只是我粘贴到我的答案中的部分。请确保您完全理解它的作用，特别是为什么[缓存破坏]（https://github.com/h5bp/html5-boilerplate/blob/v4.0.2/doc/htaccess.md#cache-busting）需要一次你用这个。 – pixelistik

我还有一个问题。你能给我一个答案吗？ – sami

您可以将它们添加到您的htaccess文件或虚拟主机配置中。

在这里看到：http://httpd.apache.org/docs/2.2/mod/mod_expires.html

但除非你拥有这些域名..他们是你的控制我们。
