App Service should enable HTTP/2

What CGPulse checks

A resource passes this rule when siteConfig.http20Enabled must equal true. Anything else is reported as a finding with the evaluated property value attached as evidence.

How to fix it

Enable HTTP/2 for improved performance via multiplexing and header compression. In Azure Portal: App Service > Configuration > General settings > set HTTP version to 2.0. See: https://learn.microsoft.com/en-us/azure/app-service/configure-common

CLI

az webapp config set --ids "{id}" --http20-enabled true

Terraform

resource "azurerm_linux_web_app" "{name}" {
  name                = "{name}"
  resource_group_name = "{rg}"
  location            = var.location
  service_plan_id     = azurerm_service_plan.{name}.id
  site_config {
    http2_enabled = true
  }
}
