Paste HTTP response headers and interpret Cache-Control directives, TTLs, validators and cache hints.
This analyzer is for reading a single response header block from dev tools, curl or a CDN log. It explains the cache directives that affect browsers and shared caches.
What it reports
The output parses public, private, no-store, no-cache, max-age, s-maxage, immutable, stale-while-revalidate, stale-if-error, Age, Expires, Vary, ETag and Last-Modified signals.
Practical limit
Cache policy depends on URL versioning and content type. Use this report as a header sanity check, then compare it with how the asset or page is deployed.
