将ExpiresByType添加到.htaccess，但PageSpeed Insights仍然声明我应该；“利用浏览器缓存”；

我已经在.htaccess中添加了以下代码，但PageSpeed Insights仍然显示了利用浏览器缓存的建议

<IfModule mod_expires.c>
ExpiresActive on
ExpiresDefault "access 1 month"
 ExpiresByType image/x-ico "access 1 year"
 ExpiresByType image/jpg "access 14 days"
 ExpiresByType image/jpeg "access 14 days"
 ExpiresByType image/gif "access 14 days"
 ExpiresByType text/html "access 2 day"
 ExpiresByType text/css "access 2 days"
 ExpiresByType image/png "access 1month"
 ExpiresByType text/x-javascript "access 1 month"  
 ExpiresByType application/javascript "access 1 month"  
 ExpiresByType application/x-javascript "access 1 month"
</IfModule>

所有列出的资源似乎都是外部的。一般来说，您不能为外部资源添加/修改头和/或缓存行为，因此对此您无能为力

只需确保您控制的所有资源（来自您的服务器和/或CDN）都正确地利用缓存。

您控制哪些服务器？感谢您的回复。。有人知道如何减少上面提到的利用浏览器兑现的问题吗？除了删除外部资源，你真的无能为力。你能做的就是将它们全部下载到你的cdn中，如果你想要满分，就为他们托管它。缺点当然是，当这些文件得到更新时，您将无法轻松地知道如何更新它们。同样具有讽刺意味的是，为了取悦谷歌，你不得不优化谷歌自己托管的文件。。。
