如何使用正确的 Apache 缓存标头设置加速 Web 开发? [英] How to speed up web development with correct Apache caching headers setup?

问题描述

尽管采取了各种措施来在 htaccess 文件中设置正确的缓存代码，但我仍然收到此错误:

Despite various measure ments to setup correct caching code in htaccess file, I still get this error:

指定缓存验证器:所有静态资源都应具有 Last-Modified 或 ETag 标头.这将允许浏览器充分利用缓存的优势.

Specify a cache validator: All static resources should have either a Last-Modified or ETag header. This will allow browsers to take advantage of the full benefits of caching.

我的 htaccess 缓存设置有什么问题吗?如果您对这些设置有改进，我会很高兴听到.非常感谢您的建议.

Is there anything wrong with my htaccess caching settings? If you have improvements for these settings i will be very happy to hear. Thank you very much for your suggestions.

<IfModule mod_headers.c>
  Header unset Pragma
  FileETag None
  Header unset ETag
  ExpiresActive On

  ##### DYNAMIC PAGES
  <FilesMatch "\\.(ast|php|css)$">
    Header set Cache-Control "public, max-age=3600, must-revalidate"
  </FilesMatch>

  ##### STATIC FILES
  <FilesMatch "\\.(png|svg|swf|js|xml)$">
    Header set Cache-Control "public, max-age=604800, must-revalidate"
    Header unset Last-Modified
</FilesMatch>

##### ETERNAL FILES
<FilesMatch "\\.(ico|jpg|gif|ttf|eot|pdf|flv)$">
    Header set Cache-Control "public, max-age=7257600, must-revalidate"
    Header unset Last-Modified
</FilesMatch>
</IfModule>

推荐答案

您特意取消了 Last-Modified 标题.那是缓存验证器部分.删除包含以下内容的行:

You are specifically unsetting the Last-Modified header. That's the cache validator section. Remove those lines that include:

Header unset Last-Modified

另外，你的css真的是动态的吗?CSS 对于许多网站来说可能是巨大的.尝试像任何其他静态内容一样缓存它.

Also, is your css really dynamic? CSS can be huge for a lot of websites. Try to cache that just like any other static content.
