Amazon S3静态Web托管缓存 [英] Amazon s3 static web hosting caching

问题描述

我将Amazon S3虚拟主机用于我的静态html，js，css(等)文件. 替换index.html文件后，在通过浏览器进行消费时，我仍然获得旧版本. 我想将默认ttl设置为存储桶(而不是存储桶中的特定对象).我找到了此链接: http://docs.aws.amazon .com/AmazonCloudFront/latest/DeveloperGuide/distribution-web-values-specify.html#DownloadDistValuesDefaultTTL

I'm using Amazon S3 webhosting for my static html,js,css (etc..) files. After replacing my index.html file, I still get the old version when consuming via the browser. I would like to set a default ttl to the bucket (and not to specific objects in it). I found this link: http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/distribution-web-values-specify.html#DownloadDistValuesDefaultTTL

，但无法在信息中心中找到对象缓存"设置.有人可以指出它在哪里吗?

but can't find the "Object Caching" setting in the dashboard. can someone point out where it is?

推荐答案

这是一个 BucketExplorer 了解更多信息.

Here's an Amazon S3 link that answers your question. According to Amazon, you can't set the cache control header for the entire bucket unless you use a third party tool (that page links to a few). One tool I ran across describes how to set the cache directives for objects submitted using a PUT request (or in bulk using their tool). See BucketExplorer for more info.

以下是Amazon指令的摘要(因为S.O.不喜欢依赖可能更改或消失的外部链接):

Here is a cut-paste of Amazon's instructions (since S.O. doesn't like to rely on external links that might change or disappear):
