Type Declaration

authoritative?

> readonly optional authoritative?: boolean

An AUTHORITATIVE resolver reads something the platform controls — the Host it serves (subdomain, custom domain) or the route it matched. Once one of them names a tenant, that answer is final: if the tenant does not exist the request resolves to no tenant, and no other resolver — above all not a client-controlled header — gets a say. Authoritative resolvers are always consulted before the others, whatever the list order.

Unmarked resolvers (including headerResolver) are fallbacks, consulted in list order only when no authoritative resolver named a tenant.
