Question

我正在使用CakePHP 2.6，此时我正在尝试修复Google PageSpeed警告，我坚持这个：

利用浏览器缓存在静态资源的HTTP标头中设置到期日期或最长期限＆gt;指示浏览器从本地磁盘＆gt;而不是通过网络加载以前下载的资源。

这是我的app / webroot / .htaccess文件

<IfModule mod_headers.c>
    Header set Connection keep-alive
</IfModule>

<ifModule mod_deflate.c>
     # compress text, html, javascript, css, xml:
     AddOutputFilterByType DEFLATE text/plain
     AddOutputFilterByType DEFLATE text/html
     AddOutputFilterByType DEFLATE text/xml
     AddOutputFilterByType DEFLATE text/css
     AddOutputFilterByType DEFLATE application/xml
     AddOutputFilterByType DEFLATE application/xhtml+xml
     AddOutputFilterByType DEFLATE application/rss+xml
     AddOutputFilterByType DEFLATE application/javascript
     AddOutputFilterByType DEFLATE application/x-javascript
     # Or, compress certain file types by extension:
     <files *.html>
         SetOutputFilter DEFLATE
     </files>
     <files *.ctp>
         SetOutputFilter DEFLATE
     </files>
</ifModule>

<IfModule mod_expires.c>
    ExpiresActive On
    ExpiresDefault "access plus 24 hours"
    ExpiresByType application/javascript "access plus 24 hours"
    ExpiresByType image/x-ico "access plus 24 hours"
    ExpiresByType image/jpg "access plus 24 hours"
    ExpiresByType image/jpeg "access plus 24 hours"
    ExpiresByType image/gif "access plus 24 hours"
    ExpiresByType image/png "access plus 24 hours"
    ExpiresByType text/css "access plus 24 hours"
</IfModule>

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]
</IfModule>

引用https://developers.google.com/speed/docs/insights/LeverageBrowserCaching

我们建议静态资产或不经常更改的资产的最短缓存时间为一周，最好为一年。

因此，请尝试将到期时间从“访问加24小时”增加到“访问加1周”。
