Chapter 20: Asynchronous Endpoints

Asynchronous communication occurs when a client sends an HTTP request that the server accepts but defers processing until later. This typically happens when the server requires additional computation time or depends on other services or user actions. In such cases, the client does not immediately receive the final result of the request. Asynchronous communication is also commonly used to increase the throughput of a web service when it needs to handle a high volume of incoming HTTP requests per unit of time.
