// When the response for the HTML file contains "Accept-CH" in the response
// headers, then the browser should not attach the specified client hints in
// the HTTP request headers if the response was delivered by an insecure HTTP
// server. Test this functionality by fetching an XHR from this page hosted on
// an insecure HTTP server. 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.
