Fast Asset Delivery with Canonical URLs
We serve assets through canonical routes and cache them aggressively at the edge.
- CDN caching with ETag and long-lived Cache-Control for immutable versions
- Conditional requests (304) for instant validations
- Streaming bytes directly from object storage for low TTFB
- Tokens for private delivery without leaking storage URLs
This post covers the delivery path, cache headers, and privacy controls at a high level.
