HTTP Long Polling

HTTP Long Polling is a web communication technique used to receive real-time updates from a server. In this method, a client (like a web browser) requests information from the server and waits for a response. Instead of closing the connection immediately, the server holds onto the request until new data is available. Once it responds, the client can either process the new information and send another request or keep waiting for more updates. This approach allows for more efficient communication compared to standard polling, where the client repeatedly asks for updates, which can waste resources and bandwidth.
