Everything you need to put Zenith CDN in front of a static origin.

Quick start

Add a CNAME for your asset hostname and point it at your assigned zone:

assets.example.com. CNAME assets.zxsten.com.

Certificates are issued automatically once the CNAME resolves. No ACME account required.

Header	Effect
`Cache-Control: max-age`	Passed through to the browser, capped at 1 year
`Cache-Control: immutable`	Object pinned at the edge, purge required to change
`Vary`	Honoured for `Accept-Encoding` only
`Age`	Added on every edge hit

Brotli is negotiated for all text-like content types; images and already-compressed archives are left untouched.

Purges propagate to all PoPs in under 300 ms. Wildcard purges are supported within a single zone.
