Long Poll

Definitions

1. A web communication technique where the client opens a request that the server holds until new data is available, then reconnects to wait again. It predates more modern realtime patterns like WebSockets for many use cases.

   In plain English: A way for a client to keep waiting on the server so updates can arrive quickly.

   Example: "The legacy dashboard still updates through long poll instead of WebSockets."
