103 Early Hints

This is a response code that provides the user client data for preloading resources. The ‘Link’ provides the information for the types of preload needed.

As this is an informational response code it is not usually viewed by users. This response code should not interfere with the operation of requests.

If another error or status code appears, troubleshoot according to the separate errors.

The HTTP 103 Early Hints information response status code is primarily intended to be used with the Link header to allow the user agent to start preloading resources while the server is still preparing a response.
