• Web technology that allows a server to push real-rime data to a client over a persistent, long-lived HTTP connection
• Highly efficient for one-way streams (live feeds, stock tickers, notifications) and automatically handles reconnections if the link drops
• Direction: One-way (Server-to-client only)
• Protocol: Standard HTTP/HTTPS
• Auto-reconnect: The browser automatically reconnects if the connection is severed
• Format: Plain text, encoded as UTF-8 (EventStream format)
• Data Limits: You cannot send binary data; everything must be text-based.
