Abstract: An increasing diversity of Web-connected devices and software capabilities has created a need to deliver optimized content for each device. This specification defines a set of HTTP request header fields, colloquially known as Client Hints, to address this. They are intended to be used as input to proactive content negotiation; just as the Accept header allows clients to indicate what formats they prefer, Client Hints allow clients to indicate a list of device and agent specific preferences.


Specified Web Concepts:

Accept-CH , Accept-CH-Lifetime , Content-DPR , DPR , Save-Data , Viewport-Width , Width
