title: Application Gateway Ingress Controller only works with root path /
body: <p>I have deployed the standard aspnet app from Microsoft, from the following YAML:</p>
  <pre><code>apiVersion: extensions/v1beta1
  kind: Ingress
  metadata:
    name: microservicesapp
    annotations:
      kubernetes.io/ingress.class: azure/application-gateway
  spec:
    rules:
    - http:
        paths:
        - path: /
          backend:
            serviceName: aspnetapp
            servicePort: 80
  ---
  apiVersion: v1
  kind: Service
  metadata:
    name: aspnetapp
  spec:
    selector:
      app: aspnetapp
    ports:
    - protocol: TCP
      port: 80
      targetPort: 80
  ---
  apiVersion: v1
  kind: Pod
  metadata:
    name: aspnetapp
    labels:
      app: aspnetapp
  spec:
    containers:
    - image: &quot;mcr.microsoft.com/dotnet/core/samples:aspnetapp&quot;
      name: aspnetapp-image
      ports:
      - containerPort: 80
        protocol: TCP
  </code></pre>
  <p>Everything works fine when I call the public IP associated with my AGW resourced. However, I want to configure the path of the ingress, so that it is <code>/test</code>. Like so:</p>
  <pre><code>  - http:
        paths:
        - path: /test
          backend:
            serviceName: aspnetapp
            servicePort: 80
  </code></pre>
  <p>When I attempt to call the endpoint from outside the cluster, this results in 502 Bad Gateway. The Controller logs after deployment of the resources in the above YAML:</p>

  <p>What is the correct way to set a path, like <code>/test</code>, so that all traffic to that path, is directed to the aspnetapp service?</p>
