Troubleshooting Cache Misses and Stale Content

Repeated cache misses reduce performance, while stale content reduces trust. Both issues are usually caused by rule design, variation conditions, or purge behavior.

Diagnostic Checklist

• Check whether cookies, query strings, or user state are bypassing cache unexpectedly.
• Review whether the page was purged after the latest update.
• Confirm that the page is intended to be cacheable in the first place.
• Inspect response headers and recent configuration changes together.

Resolution Approach

Do not change multiple cache settings at once while troubleshooting. Controlled changes make it clear which condition caused the miss or stale response pattern.
