Which HTTP client actually tries to resolve the URL to check for redirections and hence ultimately shows up in the logs of the potential URL shortening service?

* The Fedilab *app* on the mobile device?
* The home instance of the :fediverse: account that is checking for redirections?
* Some server or service run or used by Fedilab?
* Or ...?

The app makes simply a head call to get headers and check the location response.
