REST API cache control for shared cache on server?

I would like to implement some caching on my REST API server so that clients can get faster responses from cached data that is shared among them.

However, I would still like to give clients the option of getting fresh data if they prefer it.

Most examples of the HTTP cache headers I have seen assume that the data is being cached locally on the client, but I will be storing it on my server in Redis.

What is the preferred method to expose cache control functionality to clients when the cache is server-side and shared?

Thank you.
