A public URL can produce a private response
Your objectiveChoose a cache policy based on the actual response.
Understand the idea.
A normally public page may show extra information when an owner is signed in. The response’s audience therefore matters more than the route name alone. Shared caches must not reuse private state for unrelated readers. no-store, no-cache and private have distinct meanings; choose a policy deliberately and verify the observed header.
A worked example.
The anonymous homepage contains only published articles. The owner’s homepage also contains management state. Applying the same public cache header to both could violate the intended boundary even though both requests used a homepage URL.
Try the reasoning.
Write expected cache behavior for an anonymous article, an editor page and a signed-in response containing private controls. Explain which evidence would confirm the behavior at the public edge.
Carry it into practice.
Test anonymous and authenticated responses separately and omit session values from reports.
