Reference: Django comes with a robust cache system that lets you save dynamic pages, so they don’t have to be computed for each request. For convenience, Django offers cache with different granularity — from entire website to pages to part of pages to DB query results to any objects in memory. Cache middleware. If enabled, each Django-powered page will be cached based on URL.
