amazon-web-services - 如何在 Amazon S3 中使用浏览器缓存？

Question

我在 gtmetrix.com 上得到以下信息:

Leverage browser caching    
E (55)
52%
Server  High
What does this mean?
The following cacheable resources have a short freshness lifetime. Specify an expiration at least one week in the future for the following resources:

http://mysite.s3.amazonaws.com/profile.png (expiration not specified)
http://mysite.s3.amazonaws.com/circle.player.css (expiration not specified)
http://mysite.s3.amazonaws.com/main.js (expiration not specified)
http://mysite.s3.amazonaws.com/not.the.skin.css (expiration not specified)
http://cdn-images.mailchimp.com/embedcode/slim-321711.css (expiration not specified)

我猜 mailchimp 文件无法修改。但是如何为 Amazon S3 Cloudfront 文件指定浏览器缓存？

Answer 1

通过亚马逊管理控制台，选择您的文件(或文件夹)。



转到属性选项卡，然后单击元数据。



最后，将 Cache-Control 添加到其标题并保存。
