My apologies if this has been answered before, But i can't find the correct answer anywhere.
I'm looking for something that would be the equivalent of Push Notifications (or at least my understanding of them)
Explanation
I'm trying to set up a system where i can click a button & it'll essentially tell the client "This happened" (Simple explanation)
It wouldn't be a "check this saved file from * minutes ago, to see if there is any changes on remote file" As that could rack up high Bandwidth usage, I'm looking for a more If there's anything in the file, send the contents to the user.
Thank you for your time!
Further notes: The files would not be accessible locally, the most comparable thing is an rss reader.
