Using Private Cache and Session-Sensitive Pages Safely

Private caching can improve performance for dynamic sessions, but the rules must be precise. Broad rules create difficult-to-diagnose behavior.

Implementation Advice

• Identify which pages are safe for shared caching and which are not.
• Test account-specific pages after any cache rule change.
• Review how forms, notifications, and session banners behave under cache.
• Use narrow exceptions rather than broad exclusions when possible.

Operational Discipline

Cache policies should be reviewed during major workflow changes. A previously safe rule can become unsafe after a feature update.
