How to route the traffic in Application Gateway with default domain of two app services.

Hi @Syed Sujahid,Please try to create two backend pools in the application gateway and add the app services to each backend pool.

Rules -> Add backend settings

The backend settings contain the most important settings when using App Services:

Rules -> Add routing rule

Back in the rule form, scroll down to to the section “Path based routing”. Here you have to add a path based rule for each App Service:

• path “/service-a*” routes to backend pool for App Service “A”
• path “/service-b*” routes to backend pool for App Service “B”
