IETF approves new HTTP status code 103


The Internet Task Engineering Group (IETF) has approved the new http status code 103. The new status code is intended to minimize user-perceived latency. HTTP responses typically contain links to external resources that need to be fetched before they are used. $number Early hints Status code design lets browsers preload these external resource links, and the server sends header files containing external resource links before sending the primary header file, so that the browser client can preload the CSS and JavaScript files before the primary header file arrives.
