lab 11.2 ingress balancing and not routing based on host header

I've got an issue where after i've setup lab 11.2 ingress with two nginx pods and the corresponding ingress controllers and ingress rules etc. despite curling to load-balancer IP using the host header, they traffic is always balanced between the two, the host header seems to be ignored.
kubectl get pods NAME READY STATUS RESTARTS AGE myingress-ingress-nginx-controller-2jwkw 2/2 Running 281 (3d23h ago) 5d myingress-ingress-nginx-controller-bjbh9 2/2 Running 0 3d23h nfs-subdir-external-provisioner-6b958d8dd5-fqt4z 1/1 Running 16 (3d23h ago) 68d web-one-6bd47f96d7-5przs 1/1 Running 0 5d2h web-two-6bd47f96d7-4bchp 1/1 Running 1 (3d23h ago) 5d2h

Hi @dsfraser,
Are the two applications web-one and web-two distinct? Do they return different content when accessed individually, and you can tell for sure which application was accessed based on its returned response?

Thanks for the reply chris, they are both nginx web servers and as per the instructions I have adjusted the index.html file to state either EXTERNAL or INTERNAL, but what happens is if I curl to external for example I get both INTERNAL And EXTERNAL output, it's like it's ignoring the host header and just balancing.
root@master1:~# curl -H "Host: www.external.com" http://10.100.109.123
<!DOCTYPE html>
Welcome to INTERNAL!root@master1:~# curl -H "Host: www.external.com" http://10.100.109.123
<!DOCTYPE html>
Welcome to EXTERNAL!-Sam Fraser
