![]() ![]() ![]() The client sends a request to the server, which responds with the requested data. Traditionally, web browsers use a pull-based approach to fetch data from servers. It is particularly useful in building chat and messaging applications where low latency and real-time updates are crucial. Long polling is a technique used in real-time communication to achieve near-instantaneous message delivery between clients and servers. This makes it ideal in use cases that require an effective technique for building scalable and responsive chat and messaging applications as well as other apps that make use of real time data like games. Once the server has new data, it responds to the client, which can then process the data and initiate a new long polling request.īy maintaining a long-lived connection between the client and the server, long polling reduces the number of requests, minimizes latency, and improves real-time communication. The server holds the request open and waits until it has new information to send back to the client. On the other hand, long polling improves efficiency by keeping the request open for an extended period until new data is available. However, in real-time scenarios, short polling may not be efficient as it requires frequent requests to the server, resulting in unnecessary network overhead and increased latency. In traditional HTTP communication, the client sends a new request to the server and waits for a response.
