Caching can improve performance while retaining sensitive responses longer than expected. Set policy by data class.
Evaluation approach
Review client settings together with server cache headers. Prevent previous-account copies from being reused after switching.
Application example
A profile image and a detailed medical record may need different retention. Avoid unnecessary local copies.
Limits and considerations
Encrypted transport does not establish protection of cached disk data.
Do client and server policies agree?
A custom application cache may retain data even when HTTP headers restrict caching. Inventory HTTP and application caches separately, then test logout, switching and updates for both.
Checks and decisions
- Classify responses
- Inspect headers
- Test logout cleanup
