Documentation

Cache behaviour, purge semantics and supported formats for assets served from this edge node.

Cache-control overrides

Per-path overrides are read from _headers at the root of the deployed bundle:

/assets/*
  Cache-Control: public, max-age=604800, immutable

/*.html
  Cache-Control: public, max-age=300

Purge

Objects are keyed by path and ETag. A deploy that changes an asset fingerprint makes the old key unreachable, so explicit purge is only needed for non-fingerprinted paths.

Image formats

AVIF and WebP are served when the request advertises support via Accept; otherwise the original encoding is returned unchanged.

Range requests

Byte-range requests are supported for media objects. Partial responses are cached independently of the full object.
