Static cache policy
Static cache policy is one of the public readiness signals included in isitready.dev reports.
What we check
How the scan observes this signal.
During a scan, isitready.dev looks at the public evidence for static cache policy and records the result on the report card so teams can prioritise fixes without reverse-engineering the check.
Why it matters
Why this shows up on the report card.
Predictable cache headers keep assets fast while letting metadata and policy files update quickly.
How to improve
Steps in the remediation brief.
Expose the signal on the canonical public origin.
Link it from discovery surfaces such as robots.txt, sitemap.xml, HTML head metadata, or HTTP Link headers where appropriate.
Re-run the scan and confirm the evidence row now reports a passing or informational status.
