fetch follows redirects silently, so only the final URL is visible on the response

With the default redirect: 'follow', up to twenty redirect hops are traversed transparently and the resolved Response describes only the last one. response.url holds the final URL and response.redirected is true, but the intermediate status codes and their headers, including any cookies set along the way, are not observable from JavaScript. Debugging a redirect chain needs the Network panel or a server-side request.
redirect: 'manual' does not hand you the redirect either: it yields an opaque-redirect response with status 0 and no Location header, useful only for passing to a navigation. redirect: 'error' rejects instead. One subtlety catches API clients: a cross-origin redirect requires CORS headers on every hop, and a redirect that appears after a preflight for a request with custom headers is rejected outright.
