Properties

allowCrossOriginRedirects?

readonly optional allowCrossOriginRedirects?: boolean

Defined in: src/types.ts (declaration: types.d.ts:105)

Allows a redirect to leave the requested origin even when a caller User-Agent, sensitive query parameter, request body, or extra header would otherwise refuse it. File downloads need this: catalogs mint a short-lived token on their own host and redirect to a CDN. A redirect into a private network address is still refused.
