HTTP push, often referred to as server push, is a technique where the server sends data to the client without the client having to request it. This is typically used in real-time applications like live notifications, chat applications, and live updates. There are several ways to implement HTTP push, such as using WebSockets, Server-Sent Events (SSE), and HTTP/2 Push.
Here's an overview of these methods:
WebSockets provide a full-duplex communication channel over a single, long-lived connection. This is suitable for applications that require continuous data exchange.
