The article mentions rssCloud. From a cursory glance it sounds like that's a protocol extension that lets you register a callback URL to be notified about updates (i.e. push messaging).
- kevincox 3y agoYup. But in shocked to see rssCloud mentioned in 2023! It has been largely superceded by WebSub (https://www.w3.org/TR/websub/ https://www.w3.org/TR/websub/). I have yet to see a feed that supports rssCloud but not WebSub, but the reverse is common.
- hnbad 3y agoBased on my reading of rssCloud it seemed to lack a verification step so I'm glad to see the WebSub spec explicitly mention that. Without verification this seemed like an easy way to trick a server into sending random HTTP requests to third party services.
