What does Static asset cache strategy 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.
Why are hashed JS/CSS files good candidates for long caching?
When content changes, the hash in the URL usually changes too, so old URLs can use long max-age and immutable safely.
Is short caching always bad for static assets?
No. Assets without versioned URLs or with frequent changes may need short caching. Fingerprinted build assets are better suited for long caching.
