What does HTTP cache and CDN edge checker do?
It helps you inspect or process this value and get a readable result quickly.
Is my input saved?
Local tools run in the browser when possible. Server-side checks only use the input needed to complete the lookup.
How should I read Cache-Control, Age, and ETag together?
Cache-Control defines policy, Age shows how long the response has lived in cache, and ETag supports revalidation. Together they show whether caching is likely working.
Can CDN cache hits always be seen in response headers?
No. CDNs expose different headers and some hide hit signals. This tool reads public clues; CDN dashboards remain the source of truth.
Should llms.txt and robots.txt use long caching?
Avoid overly long caching. They are discovery entry files for search and AI systems, so keep them publicly cacheable with a short refresh window and recheck Content-Type, status, and sitemap links after changes.
