 The nginx ingress controller will read the `ingress-nginx/ingress-nginx-controller` ConfigMap, find the `proxy-set-headers` key, read HTTP headers from the `ingress-nginx/custom-headers` ConfigMap, and include those HTTP headers in all requests flowing from nginx to the backends.
 
+
+The above example was for passing a custom list of headers to the upstream server.
+To pass the custom headers before sending response traffic to the client, use the add-headers key:
+
+```console
+kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/main/docs/examples/customization/custom-headers/configmap-client-response.yaml
+```
+
 ## Test
 
 Check the contents of the ConfigMaps are present in the nginx.conf file using:
-`kubectl exec ingress-nginx-controller-873061567-4n3k2 -n ingress-nginx -- cat /etc/nginx/nginx.conf`
+`kubectl exec ingress-nginx-controller-873061567-4n3k2 -n ingress-nginx -- cat /etc/nginx/nginx.conf`
