Cache-Control interactive explainer

Change the response policy and watch how the browser cache changes the next request.

What to notice #

• max-age allows a browser to reuse a response without a request while it is fresh.
• no-cache can still store a response, but it must revalidate before reuse.
• no-store should not keep a reusable response.
• immutable tells the browser that a fresh response will not change at the same URL.
• stale-while-revalidate favors speed by showing stale content while refreshing the cache.
