大多数主流浏览器都支持HTTP / 2，因此如果您的服务器支持 HTTP / 2支持，您的用户可能会从中受益。尝试使用RC更新。

IIS在Windows 10 Beta中支持HTTP / 2
虽然我清楚地了解Windows 10是浏览器支持所必需的，但我找不到关于所需的Windows Server / IIS版本的明确答案-Wiki答案“ IIS在Windows 10 beta中支持HTTP / 2”没有意义，因为它们是直到明年才发布Windows 10服务器。
我一直在寻找答案，却一无所获。如果我们拥有Server 2008 R2和Server 2012 R2，它们将向Windows 10客户端返回HTTP / 2吗？
谢谢
Answers:
IIS版本绑定到OS版本，而Windows Server 2016上的IIS 10直到2016年才发布，Windows 10的IIS 10于2015年7月29日发布，并支持HTTP / 2。
除了支持HTTP / 2 ，IIS 10还提供了其他一些新功能，但是Microsoft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，Microsoft从未向该产品的旧版本提供任何新的IIS核心功能，因此，这次他们不太可能这样做。
考虑到大量的IIS 7.x和8.x服务器以及http / 2带来的好处，如果这次他们考虑new Microsoft所有和全部内容，然后改变此策略，那将非常好，但是我仍然怀疑那。
