Set up Nexus Repo 3.33.1. Configure a pypi hosted and group repository:
Request metadata for a package through the group using "curl -v":
Observe that no Etag header is returned. Make the same request through the proxy repository. Observer that an Etag header is returned.
Expected: Returning an Etag header is critical to performance, without it pypi clients will continuously be downloading the same package metadata from the group repository.
