Support HTTP/2
If you host the PowerServer Web APIs in IIS 10.0 or later, or run
the PowerServer Web APIs using the built-in ASP.NET Core (3.0 or later)
Kestrel server, PowerServer automatically supports HTTP/2. You don’t
need to change any setting in PowerServer or IIS for HTTP/2 to work, as
it is enabled by default in IIS 10 or later and ASP.NET Core 3.0 or
later. For more, refer to https://docs.microsoft.com/iis/get-started/whats-new-in-iis-10/http2-on-iis
or https://docs.microsoft.com/aspnet/core/fundamentals/servers/kestrel/http2.
If you host the PowerServer Web APIs in Apache 2.4.17 or later and
OpenSSL 1.0.2 or later, PowerServer automatically supports
HTTP/2.
If you host the PowerServer Web APIs in Nginx 1.9.5 or later and
OpenSSL 1.0.2 or later, PowerServer automatically supports HTTP/2. For
more, refer to http://nginx.org/en/docs/http/ngx_http_ssl_module.html#ssl_protocols.
