Description

Enabling HTTP/2 for Azure App Service is essential for improved security and performance, as HTTP/2 offers better data encryption, reduced latency, and protection against certain protocol-level attacks. If the http2_enabled attribute is not set to true in the site_config block, as shown below, the app service will only support HTTP/1.1, making it more vulnerable to downgrade attacks and less efficient in handling modern web traffic.

site_config {
  http2_enabled = true
}

Neglecting to enable HTTP/2 may expose applications to increased risks and degrade the overall performance and user experience.
