Set-Cookie标头中的Priority = High是什么意思？ [英] What does Priority=High mean in the Set-Cookie header?

问题描述

我一直在查看Chrome在Fiddler中的流量，发现有些我不明白的东西：

I've been looking at Chrome's traffic in Fiddler, and I found something that I feel I don't understand:

Set-Cookie: GAPS=1:ZYBtVMzURzU2umKMxZThJ2lVPxy3Hg:SvHhlG2k1Vy5pnA0;Path=/;Expires=Wed, 04-Nov-2015 20:44:37 GMT;Secure;HttpOnly;Priority=High

我找不到有关 Priority = High 的用途的任何文档。是什么意思？

I can't find any documentation on what Priority=High is for. What does it mean?

推荐答案

基本上，这至少是chrome的规格（我在其他浏览器中看不到）允许在重新验证Cookie时对它们进行优先级排序。当cookie超过每个域的cookie容量时，它们将被删除。 Cookie优先级使服务器可以删除较低优先级的旧Cookie，并且即使较旧也可以挂在较高优先级的Cookie上。

Basically this is a spec by at least chrome (I didn't see it for other browsers) that allows cookies to be prioritized for when they are re-authenticated. Cookies get deleted when they exceed per-domain cookie capacity. The cookie-priority allows servers to remove old cookies at lower priorities, and hang onto higher priority cookies longer, despite being older.
