哪些浏览器支持“过时错误"和“过时重新验证"? [英] Which browsers support stale-if-error and stale-while-revalidate?

问题描述

RFC 5861 提出了

RFC 5861 proposes the Cache-Control extensions stale-while-revalidate:

在HTTP响应中存在时，过时的重新验证缓存"-控制扩展表示缓存可以在变陈后出现的数字，直到指定的数字秒.

When present in an HTTP response, the stale-while-revalidate Cache- Control extension indicates that caches MAY serve the response in which it appears after it becomes stale, up to the indicated number of seconds.

和 过时的错误 :

过时的错误Cache-Control扩展指示当遇到错误，可以使用缓存的过时响应来满足该请求，而与其他新鲜度信息无关.

The stale-if-error Cache-Control extension indicates that when an error is encountered, a cached stale response MAY be used to satisfy the request, regardless of other freshness information.

当无法重新验证响应时，允许较长时间使用过时的内容.

to allow stale content to be used for longer when a response cannot be revalidated.

这些是CDN支持的 ，其中包括快速和

These are supported by CDNs, including Fastly and KeyCDN.

stale-while-revalidate 也是(不是 stale-if-error ).

浏览器的支持状态是什么?

What is the state of support in browsers?

推荐答案

根据Chrome ，同时失效的是:

• 受 Firefox 68 beta版本( Chrome 75受支持(这些将是这些浏览器在 2019-07-09 和<分别分别是href ="https://www.chromestatus.com/features/schedule" rel ="nofollow noreferrer"> 2019-06-09 .

  These will be the main releases of those browsers on 2019-07-09 and 2019-06-09 respectively.

  过时错误似乎没有当前或计划的支持.

  stale-if-error doesn't appear to have current, or planned, support.

  (请参阅RFC作者的博客 Chrome和Stale-While-重新验证，详细了解为什么在浏览器中实现此功能.)

  (See the RFC author's blog Chrome and Stale-While-Revalidate for more detail on why to implement this in browsers.)
