...它指出...
大多数主流浏览器都支持 HTTP/2，因此您的用户很可能会受益于 HTTP/2 支持如果你的服务器支持的话. 尝试一下 RC 更新。

IIS 在 Windows 10 beta 版中支持 HTTP/2
虽然我清楚地知道 Windows 10 是浏览器支持所必需的，但我无法找到关于需要什么版本的 Windows Server/IIS 的明确答案 - Wiki 答案“IIS 在 Windows 10 beta 中支持 HTTP/2”毫无意义，因为他们要到明年才会发布 Windows 10 服务器。
我搜索了答案，但一无所获。如果我们有 Server 2008 R2 和 Server 2012 R2，它们会将 HTTP/2 返回给 Windows 10 客户端吗？
谢谢
答案1
IIS 版本与操作系统版本绑定，而 Windows Server 2016 上的 IIS 10 要到 2016 年才会发布，而 Windows 10 的 IIS 10 于 2015 年 7 月 29 日发布，并且支持 HTTP/2。
除了支持 HTTP/2 之外，还有其他一些IIS 10 中的新功能但微软可能会在发布 Server 2016 之前添加更多功能
在 IIS 的整个生命周期中，微软从未向该产品的旧版本提供任何新的核心 IIS 功能，因此这次他们不太可能这样做。
考虑到 IIS 7.x 和 8.x 服务器的数量众多以及 http/2 带来的好处，如果他们这次能改变这项政策，那就太好了，考虑到new Microsoft所有因素，但我仍然对此表示怀疑。
