HTTP 103 Early Hints is a informational-class status code defined in RFC8297. Preliminary hints (e.g. Link headers) sent before the final response so the browser can preload assets.
Informational responses tell the client the request was received and the conversation continues — they are interim, never final. On the wire, the response begins with the status line HTTP/1.1 103 Early Hints.
