WTN Market cache-control freshness audit
Review caching headers and visible update dates when a WTN Market status page appears stale. This guide treats WTN Market and WTNMarket search terms as research labels, not as proof that a destination is official or safe.
Distinguish cache age from content age
A cached response may be recent even when the underlying WTN Market statement is old. Record both the HTTP cache indicators and the visible editorial date.
Do not describe a page as updated merely because a proxy fetched it again.
Inspect the relevant headers
Review Cache-Control, Age, ETag, Last-Modified and validation responses as a group. Each field has a different role and none proves that a mirror claim is accurate.
Preserve the observation time and request URL so another reviewer can reproduce the result.
Compare browser and origin behavior
A browser refresh, edge cache and origin request may show different ages. Explain which layer was tested instead of presenting one response as universal.
When content differs across layers, keep the public link status neutral until the canonical page is consistent.
Correct signals together
After a real editorial change, update visible wording, structured data and sitemap lastmod. Purge or revalidate caches only within the authorized publishing workflow.
Submit the changed canonical through IndexNow once the current version is publicly reachable.
Frequently asked questions
Does a recent Last-Modified header prove fresh WTN Market content?
No. It is a server signal and must be compared with the visible editorial change.
Should cache checks update sitemap lastmod?
Only when they lead to a substantive public content change.
