Artifactory is not caching the helm chart from datadog repository

Configure a helm-remote repository pointing to https://helm.datadoghq.com and add this to a helm-virtual repository . Now, configure the helm client to point to Artifactory.

helm repo add helm https://myart.jfrog.io/myart/helm --username amithkm --password password 

Get the API key from the datadog by registering at  https://app.datadoghq.com/ 

helm install helm/datadog --version 2.4.20 --set datadog.apiKey=4f0440ba2bf59d199287232e92ebda0c --debug

NOTES:

Datadog agents are spinning up on each node in your cluster. After a few

minutes, you should see your agents starting in your event stream:

**truncated the output for simplicity. (gives the status of pods). 

Impact or Issue:- Artifactory is not caching the actual chart in helm-remote-cache repository. The only cached item is index.yaml which contains the location of the chart in github page (

urls:

• https://github.com/DataDog/helm-charts/releases/download/datadog-2.4.20/datadog-2.4.20.tgz)

The issue same across all the versions in Artifactory 6 and 7.
