 # Tutorial: Build a chatbot with Azure App Service and Azure OpenAI (Flask)
 
-In this tutorial, you'll build an intelligent AI application by integrating Azure OpenAI with a Python web application and deploying it to Azure App Service. You'll create a Flask app that sends chat completion requests to a model in Azure OpneAI.

 Application Gateway Subnet is the subnet within the Virtual Network where the Application Gateway Resources will be deployed. In the Frontend Private Ip configuration, is important that this subnet can reach privately the resources that want to connect to your exposed app or site.
 
+> [!NOTE]
+> As of May 5, 2025, new and existing deployments of Private Application Gateway require Subnet Delegation to `Microsoft.Network/applicationGateways`.

 ## Outbound Internet connectivity
 
 Application Gateway deployments that contain only a private frontend IP configuration (do not have a public IP frontend configuration associated to a request routing rule) aren't able to egress traffic destined to the Internet. This configuration affects communication to backend targets that are publicly accessible via the Internet.
