Caching

Caching Policy

Weekerp CDN caches transformed images for up to one year after the first request. When the same request (same URL and parameters) is repeated, the cached image is instantly served to maximize delivery speed.

---

Cache Duration

• Transformed images are stored on CDN edge servers for up to 1 year.

• The same combination of URL and parameters always references the same cache.

• After expiration, the first subsequent request automatically regenerates and updates the cache.

---

Cache Key Criteria

Cache entries are distinguished based on the entire request path + parameters. For example, the following two requests generate separate cache entries:

/image/cat.jpg?w=800
/image/cat.jpg?w=800&fit=cover

---

Cache Purge

Currently, no official cache purge feature is provided. However, if you urgently need to remove cached content, please contact [e-mail] for manual assistance.

---

Versioning (Recommended)

Instead of manually purging cache, you can append a version parameter (v) to the image URL to achieve the same effect safely and instantly.

/image/cat.jpg?w=800&v=2

Changing the v value creates a completely new cache entry, allowing the latest image to be served immediately without touching existing caches.

💡 Tip: Use a timestamp or build version for the v parameter to safely refresh caches on every new release.
