- A `302` response to a ZIM (as is in this case) is normal. MB sends a `Location` header to the most appropriate mirror.
- `Transmission/4.0.5` is a bittorrent client.
- Our torrent does not include this URL. It contains a list of the mirrors links instead (see below)
- Our magnet link (generated by mirrorbrain) includes only that URL in the [Acceptable Source `as` field](https://en.wikipedia.org/wiki/Magnet_URI_scheme) (fallback).
- Testing with Transmission/4.0.6, I dont seem to trigger any request, while it reports downloading from the webseed (and the peers)
- [Transmission changelog](https://github.com/transmission/transmission/releases/) does not indicate any fix in this regard
