HTTP 103 Early Hints

Informational

An interim response that lets the server send Link headers (preload/preconnect) before the final response is ready, so browsers can start fetching critical assets earlier.

Defined in RFC 8297

Common causes

  • Server or CDN configured to emit early hints while the origin renders

How to fix it

  1. Nothing to fix — it is a performance optimization

  2. Ensure clients that can't handle interim responses ignore it gracefully
