That uses only one web seed URL: an IPFS gateway link to a file (assuming &ws= is hashed by the infohash like &tr= is). Months ago in /mlp/, someone wondered if archive.org could be used as a webseed. A reply was basically this: data can be uploaded to IA via torrent(s), but IA will only leech it (and may not seed it while leeching) until 100% then stop interacting with it; then IA will only seed the autogenerated torrent. What was missing from that reply: a webseed URL -- such as https://archive.org/download/deskjetf2400allin1driver/DJ_AIO_06_F2400_NonNet_Full_Win_WW_140_175-4.exe (for "HP DeskJet F2400 All-in-One Printer Driver" in BitTorrent) -- can be used in a torrent and it will work. As long as that archive.org link is not loginwalled and not deleted, then it will work in such a torrent. Also, don't use a resolved link like https://ia802908.us.archive.org/28/items/deskjetf2400allin1driver/DJ_AIO_06_F2400_NonNet_Full_Win_WW_140_175-4.exe because those are unstable. For web seed links to work, they must to be all of the following: HTTP(S), online, accessible, and matching to the torrent file.

I have seen web seed URLs used for single-file torrents, but do they work with multiple-file torrents? IDK. How I think that could work: you could specify a URL like https://gateway.pinata.cloud/ipfs/bafybeieuw6nzerkvpgn2n4ltaphhowdetpxpwpamboqhzttrqo4gucaglq/ (offline) and have a torrent which contains all of those files related to that HP DeskJet driver; then, it would check that gateway.pinata.cloud webseed link and add the filenames to the end of the URL. It either works as a 1:1 mapping or a 1:many mapping. With 1:1 you have to have a webseed URL for each file in the torrent. With 1:multiple, you could have one URL -- say https://example.com/myfiles/ -- and it would then check https://example.com/myfiles/[torrent_file_1], https://example.com/myfiles/[torrent_file_2], etc.

Speaking of a hashtree or folder with multiple files, here's the CID for the extracted version of that torrent (copied):
