Although support for HTTP/2 was introduced in Azure App Services more then a year ago, HTTP 1.1 is still the default when you create a new App Service.
As HTTP/2 brings a lot of performance improvements, it can be worth to make the switch. Let’s see how to enable this:
- Go to the Azure Portal and select the App Service you want to configure from the list of Resources
- Click on the Settings –> Configuration item to open the Configuration blade.
- Click on the General settings and scroll down to the Platform settings
- Change the HTTP version to 2.0 and click on Save.
