Harbor proxy cache is not pull-through cache

[stonezdj]

It should be updated to proxy cache

@stonezdj the proposal naming says otherwise.

We need to discuss this clearly before moving on. Since, there seems to be some ambiguity because the docs and git history show different approaches. Could we clarify the intended behavior before proceeding?

While distribution already does the https://distribution.github.io/distribution/recipes/mirror (pull through cache) - Harbor being better implementation of distribution. As a user I would believe harbor to inherently have pull through cache not a proxy cache.

Its good to note that pull through cache is the widely used in registry and these data intensive applications. whereas proxy cache is something that is widely used for webservers and websites.

We need to be a bit more clear.

given that a lot of people are waiting for this to be merged #22153. it might be premature to move entirely toward an online-only proxy cache.

Thanks
