How To Use Cloudflare Early Hints in your websites and apps that are currently using Cloudflare? Early Hints by Cloudflare is a Brand New addition to their speed optimizations where you can see an almost 30% speed boost in web content loading by using 103 response Code which is the new HTTP Status Code for Indicating Hints for preloading Webpage content before response code 200 that means a lot faster routing for the specific link –

What is the 103 Early Hints Code?

According to httpwg.org

The 103 (Early Hints) informational status code indicates to the client that the server is likely to send a final response with the header fields included in the informational response

Typically, a server will include the header fields sent in a 103 (Early Hints) response in the final response as well. However, there might be cases when this is not desirable, such as when the server learns that the header fields in the 103 (Early Hints) response are not correct before the final response is sent

Examples of 103 Early Hints

Client request:

  GET / HTTP/1.1
  Host: example.com

Server response
