Disable Http2 on Windows Server 2016 at Site Level

Question

Anyone know if there is a way at the site level to disable HTTP/2.0 on Windows Server 2016? Disabling server-wide is not an option.

Answer 1

I know this is old question, but I had hard time to find proper answer my self, so I'm answering here for reference.

On Windows Server 2016 you can only disable HTTP/2 server-wide (how to do it is described here: How to disable HTTP/2 on IIS 10).

Windows Server 2019 added added flag for control of HTTP/2 per site:

• In IIS Manager right click on site.
• Click Edit Bindings....
• Select https binding and click Edit... or click Add... if such binding doesn't exist.
• Check Disable HTTP/2 checkbox.
