// If the response for the HTML file contains "Accept-CH" in the response
// 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".
//
// echo_client_hints_received.py includes "device-memory-received",
// "dpr-received" and "viewport-width-received" in the response headers
// depending on the set of client hints it receives in the request headers.
