Review which query parameters belong in a CDN cache key
Compare content variants, private responses, and ignored tracking parameters.
Readiness check
Is the handoff ready?
Use this table before you send the first ticket. Fix the weak spots while access is still limited.
| Area | Ready | Needs work |
|---|---|---|
| Question | One observable CDN cache keys outcome | A request to inspect the whole system |
| Fixture | a test hostname with synthetic public responses and controlled parameters | Customer data or shared credentials |
| Evidence | URL, normalized key, response marker, cache status, age, headers, and purge result | A pass label without observed values |
| Approval | Web and security owners approve cache rules and private-response handling. | The contractor changes production alone |
Reproduce the CDN cache keys failure safely
A missing parameter can serve the wrong variant while an unnecessary one splinters the cache. Start with one case that can fail without touching customer records or production infrastructure. Write the expected result, stop condition, and reviewer beside the fixture.
Use a test hostname with synthetic public responses and controlled parameters. Label every identity and artifact so a reviewer can distinguish test evidence from a live record.
Leave enough evidence for a second person
Capture URL, normalized key, response marker, cache status, age, headers, and purge result. Include the source revision and test time. If behavior changes between runs, retain both results.
Web and security owners approve cache rules and private-response handling. A remote programmer can prepare the fixture, run bounded checks, and explain the result. New policy, privileged access, and release approval stay with the named owner.
