Native HTTP 103 Early Hints
Early Hints is a feature that allows browsers to start a pre-load phase of some assets called in the HTML page, such as CSS, JS, Font or Image dependencies.
Early Hints allows browsers to override the server thinking time
iSmartFrame send these hints to a browser before the full response is prepared, so the browser can figure out what is needed to load the webpage faster for the end user.
