Headers affect storage by clients, intermediaries and CDNs. Defaults may be inappropriate for account-specific data.
Evaluation approach
Classify responses and verify separation between user-specific cache keys and shared caches.
Application example
A profile response must never serve another user's request. Test switching and logout against old copies.
Limits and considerations
Disabling caching does not replace authorization or encryption.
When does data become stale?
Permission changes and account deletion can invalidate content before its nominal expiry. Connect invalidation to business rules, not only performance settings.
Checks and decisions
- Inspect headers
- Test user isolation
- Review local copies
