There are many use cases where additional processing happens after the main request handling is complete, typically in web servers, APIs, or distributed systems:

For example -

  1. Logging - Record request/response data after handling

  2. Analytics -  Send metrics to Prometheus, Datadog, etc.

  3. Security Auditing - Capture actions for regulatory compliance

  4. Asynchronous Notification - Trigger follow-up actions in background like publlishing messages to Message Queues like Kafka.

  5. Resource Cleanup - Clean up resources related to request
