| // duration specified in the Accept-CH-Lifetime header. |

| // Next, to verify if the origin preferences were persisted by the user |
| // agent, this test fetches resources/expect_client_hints_headers.html |

| // verifies that the user agent actually sends the client hints in the request |
| // headers. |
