Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

HTTP/2 Early Hints Rack middleware

It sends extra responses before the main response is sent. These extra responses are HTTP/2 Early Hints (103). They specify the web assets (javascripts, stylesheets, etc..) to be “pushed”, so modern browsers pre-fetch them in parallel with the main HTTP response.
