Currently there is support for BEP-19: WebSeed - HTTP/FTP Seeding (GetRight style), but not for the other HTTP Seeding mechanism specified in BEP-17 which adds the "url-list" key.
BEP-17 HTTP seeding is superseeded by BEP-19 and should not be used in new torrents, but it is still usefull to support this for editing and inspecting older torrent files.
