If Portal is used with an k8s ingress e.g. config below, then SDC for example will not launch correctly.

The problem is that Portal adds cookies with underscores "_" e.g.  USER_ID=cs0008 

These are stripped out by default by the nginx ingress.

This can be overriden by setting 

enable-underscores-in-headers: "true"

in the ingress 

example of now to change

kubectl -n  ingress-nginx get cm nginx-configuration -o yaml > nginx-CM.yaml

add the 2 lines below to  nginx-CM.yaml

data:
  enable-underscores-in-headers: "true"

kubectl replace -f  ./nginx.yaml

sample INGRESS is  attached

I think this either needs to be documented on how to set up an ingress for ONAP or I think the usage of underscores should be removed.
