Browser Cache Policy Checker
Paste headers from curl, DevTools, or a CDN. The checker explains max-age, immutable, and no-store, and flags policies that keep old HTML or files after a deploy.

Response headers
Paste a Cache-Control line or a full header block. Choose the resource type so HTML and hashed files are judged differently.
Parsing stays in this browser. Headers are not uploaded.
Cache-Control directives
Each token from Cache-Control is listed so max-age, immutable, and no-store are easy to scan.
No Cache-Control directives found.
Safer Cache-Control
A starting value for this resource type. Adjust CDN s-maxage separately if needed.
