Mastering Django Web Development (Video 17)

The video tutorial discusses the importance of caching in applications, focusing on three types: low-level caching, caching with middleware, and template caching. It explains how low-level caching allows control over what gets cached, introduces cache backends like Memcached and Redis, and suggests using a database as a cache backend for simplicity.
