What are some examples of long polling in web applications?

Long polling is a technique where the client requests information from the server and the server holds the request open until new data is available. Examples include chat applications, real-time notifications, and live updates on dashboards.

Can you explain how long polling differs from regular polling?

Sure! In regular polling, the client repeatedly requests data at fixed intervals, regardless of whether new data is available. Long polling, on the other hand, keeps the connection open until the server has new data to send, reducing unnecessary requests.

What are the advantages of using long polling?

The main advantages of long polling include reduced latency for receiving updates, lower server load compared to regular polling, and a more efficient use of network resources.

Are there any downsides to using long polling?

Yes, some downsides include increased complexity in implementation, potential issues with connection limits on the server, and the need for proper error handling and reconnection strategies.
