AWS CloudFront 如何检测移动设备
How Does AWS CloudFront Detect Mobile Devices
AWS CloudFront 可以根据 User-Agent header:
的值检测设备类型
If you want CloudFront to cache different versions of your objects
based on the device a user is using to view your content, configure
CloudFront to forward the applicable headers to your custom origin:
- CloudFront-Is-Desktop-Viewer
- CloudFront-Is-Mobile-Viewer
- CloudFront-Is-SmartTV-Viewer
- CloudFront-Is-Tablet-Viewer
Based on the value of the User-Agent header, CloudFront sets the value
of these headers to true or false before forwarding the request to
your origin. If a device falls into more than one category, more than
one value might be true. For example, for some tablet devices,
CloudFront might set both CloudFront-Is-Mobile-Viewer and
CloudFront-Is-Tablet-Viewer to true.
我想知道 AWS 是否发布了用于检测移动浏览器的用户代理列表。
文档中提到了"If a device falls into more than one category"，所以我需要知道它是如何确定这些类别的。
AWS 使用基于用户代理检测设备，但不提供任何详细信息。
