> MsQuic is shipped in-box in the Windows kernel in the form of the msquic.sys driver

Does that mean that a HTTP.SYS Webserver will also Support QUIC?

[slowstart]

We are currently testing HTTP/3 support in IIS/http.sys internally. Cannot comment on any external product release timelines.

You mean IIS? HTTP.SYS isn't a webserver.

[convFixb]

HTTP.SYS is the core of a Windows NT native web server; the async listen/accept loop, IOCP-based data transfer, etc. IIS is built on top of HTTP.SYS. I presume that it ships with Windows for ease of servicing; it is after all a kernel-mode driver (of sorts).

[legulere]

The kernel module HTTP.SYS contains a HTTP server. It's used by IIS, but you can also use its API directly.

Wow, didn't know that.
