What it means

A 103 Early Hints response lets the server send important headers, like Link headers for preloading resources, before the final response is ready. This can help browsers start loading critical assets earlier and improve page performance.

Common causes

• The server is using early hints to optimize page load performance.
• Resource preload directives are being sent ahead of the main response.

How to fix it

• No action needed. This is a performance optimization, not an error.
