| // 1. The audio element sends the first request. |
| // - If |original| is 'same', the request is same-origin request. |
| // - If |original| is 'cross', the request is cross-origin request. |
| // 2. The Service Worker may intercept the request depending on |first_byte|. |
| // - If |first_byte| is '', the SW doesn't intercept, and the native server |
| // returns the all data response and the test finishes. |
| // - If |first_byte| is 'gen', the SW generates and returns the first byte |
| // response 'O'. |
| // - If |first_byte| is 'same', the SW does a fetch to |
| // 'service-worker-mixed-response.php' in the same origin server and returns |
| // the response. |
| // - If |first_byte| is 'cross', the SW does a fetch to |
| // 'service-worker-mixed-response.php' in the cross origin server and |
| // returns the response. |
| // 3. The element sends the second request with "Range: bytes=1-" header. |
| // 4. The Service Worker may intercept the request depending on |second_byte|. |
| // - If |second_byte| is '', the SW doesn't intercept, and the native server |
| // returns the remaining data response and the test finishes. |
| // - If |second_byte| is 'gen', the SW generates and returns the second byte |
| // response 'g'. |
| // - If |second_byte| is 'same', the SW does a fetch to |
| // 'service-worker-mixed-response.php' in the same origin server and returns |
| // the response. |
| // - If |second_byte| is 'cross', the SW does a fetch to |
| // 'service-worker-mixed-response.php' in the cross origin server and |
| // returns the response. |
| // 5. The element sends the third request with "Range: bytes=2-" header. |
| // 6. The native server returns the remaining data. |
| // |
| // When the audio element recieves the first response, it remembers the original |
| // URL of it. And when it receives the succeeding response, it checks the origin |
| // of the new response. If the origin is not same as the origin of the first |
| // response, the response must be treated as an error. |
