The aim of caching is to never have to generate the same response more than once. The key benefits of using this strategy are an increase in speed and a reduction in server processing.

Essentially, the request flows through a cache or a series of caches, such as local caching, proxy caching, or reverse proxy caching, in front of the service hosting the resource. If any of them match with any criteria during the request (for example, the timestamp or client ID), the data is returned based on the cache layer, and if the caches cannot satisfy the request, the request goes to the server:
