| // client. These variations are included in network requests sent to Google: the |
| // proto contents are serialized, B64 encoded, and sent to Google web properties |
| // as part of the X-Client-Data request header. You can view the exact data sent |
| // from your client via the Developer Tools UI: |
| // https://developer.chrome.com/blog/new-in-devtools-86#x-client-data. |
| // |
| // On Android Chrome, in certain cases these Google-visible variations may also |
| // be sent to Google apps when cross-app communication occurs to support a |
| // Chrome feature – for example, when searching with Google Lens. This |
| // information is used to better understand how Chrome variations affect that |
| // feature – for example, Chrome memory usage change could affect how long it |
| // takes an action in the Google app to complete. |
| // |
| // NOTE: If you update this proto, you'll also need to rebuild the JS parser for |
| // devtools. See //components/variations/proto/devtools/BUILD.gn for details. |
