设置HTTP缓存过期，推荐由谷歌PageSpeed

本文介绍了设置HTTP缓存过期，推荐由谷歌PageSpeed的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我跑了使用谷歌的PageSpeed在我的网站的测试，并建议我杠杆浏览器缓存，并提供以下资源：

I ran tests on my website using Google's PageSpeed and it recommends that I "Leverage browser caching" and provided the following resource:

<一个href="http://$c$c.google.com/speed/page-speed/docs/caching.html#LeverageBrowserCaching">http://$c$c.google.com/speed/page-speed/docs/caching.html#LeverageBrowserCaching

这个资源没有解释如何真正改变我的HTTP头文件的截止日期。做到这一点通过的.htaccess？我想设置缓存尽可能长的时间（不违反一年最大的谷歌的政策）。

This resource never explains how to actually change the expiration date of my http headers. Do I do this through .htaccess? I would like to set the caching for as long as possible (without violating Google's policy of a year max).

在推荐设置（为自定义PHP驱动的社交网络社区）的任何意见将是极大的AP preciated。

Any advice on recommended settings (for a custom php-driven social networking community) would be greatly appreciated.

推荐答案

在你的根目录的htaccess的：

In your root's .htaccess:

<IfModule mod_expires.c>
  ExpiresActive On
  ExpiresDefault "access plus 1 seconds"
  ExpiresByType image/x-icon "access plus 2592000 seconds"
  ExpiresByType image/jpeg "access plus 2592000 seconds"
  ExpiresByType image/png "access plus 2592000 seconds"
  ExpiresByType image/gif "access plus 2592000 seconds"
  ExpiresByType application/x-shockwave-flash "access plus 2592000 seconds"
  ExpiresByType text/css "access plus 604800 seconds"
  ExpiresByType text/javascript "access plus 216000 seconds"
  ExpiresByType application/x-javascript "access plus 216000 seconds"
  ExpiresByType text/html "access plus 600 seconds"
  ExpiresByType application/xhtml+xml "access plus 600 seconds"
</IfModule>

和遵循：

<IfModule mod_headers.c>
<FilesMatch "\\.(ico|jpe?g|png|gif|swf)$">
Header set Cache-Control "max-age=2692000, public"
</FilesMatch>
<FilesMatch "\\.(css)$">
Header set Cache-Control "max-age=2692000, public"
</FilesMatch>
<FilesMatch "\\.(js)$">
Header set Cache-Control "max-age=216000, private"
</FilesMatch>
<FilesMatch "\\.(x?html?|php)$">
Header set Cache-Control "max-age=600, private, must-revalidate"
</FilesMatch>
Header unset ETag
Header unset Last-Modified
</IfModule>

这是完全相同的code我对每个属性我管理，并提供我（和PageSpeed）最满意的效果，请使用。有人可能会说在特定的规则，这就是为什么我说，它满足的我，但它肯定满足PageSpeed。

This is the exact same code I use on every property I manage and offers me (and PageSpeed) the most satisfying results. One may argue on specific rules, that's why I said that it satisfies me, but it certainly satisfies PageSpeed.
