Frontend Request Caching and Cancellation Strategies(Idempotency API)

Описание: It outlines various caching mechanisms like in-memory, local storage, and HTTP caching, detailing their pros, cons, and appropriate use cases for idempotent GET requests. Additionally, the document thoroughly covers how to cancel in-flight requests using AbortController in conjunction with beforeunload or router events to prevent wasted resources, inconsistent states, and race conditions, particularly emphasizing idempotency for non-read operations on the backend. The integration of these techniques is then illustrated with code examples for a comprehensive approach to efficient and reliable frontend data fetching.
