How to enable http2 in Azure?

Question

Although I have enabled Http/2 in Azure, it is not working. When I run locally my api, http/2 is working.

Edit 1

I have a net core 3 web api and I want to publish to an azure web app. I followed the instructions of microsoft's page, but when I check the protocol on HttpContext.Request.Protocol I got HTTP/ 1.1.

Is something else that I should add to my code or other configuration on Azure web app that I missed?

Thanks

In 2021, it's in your app service sidebar -> settings -> configuration.

From there it's under the "tab" general settings, halfway down the page.

If you are talking about Azure web app, you need to use resource explorer and change the “http20Enabled” to the desired value.

From resource explorer, follow this blog https://blogs.msdn.microsoft.com/benjaminperkins/2018/04/18/how-to-disableenable-http2-azure-app-service/

Through the Azure portal, browse to your app and search for the “Application settings”, where you will find the setting called “HTTP Version”. Select 1.1 or 2.0 by your needs.

From portal, follow this official announcement https://azure.microsoft.com/en-us/blog/announcing-http-2-support-in-azure-app-service/?ref=msdn

If you have concern about any other azure service, do let me know.
