Real-time web
The document discusses the real-time web and various technologies used to enable real-time functionality on the web, including REST, websockets, streaming, webhooks, PubSubHubbub, and XMPP. Real-time updates are more efficient than periodic polling of data. Emerging standards like websockets allow for real-time data streams between clients and servers. Publish-subscribe protocols allow subscribers to receive real-time updates from publishers when data changes.
