// headers, then the browser should attach the specified client hints in the
// HTTP request headers depending on whether the resource is being fetched from
// the same origin or a different origin. Test this functionality by fetching
// same-origin and cross-origin resources from this page. The response headers
// for this page include "Accept-CH: device-memory, dpr, viewport-width, rtt, downlink, ect".
//
// echo_client_hints_received.py sets the response headers depending on the set
// of client hints it receives in the request headers.
