Server side caching works by storing a copy of the generated output in a temporary storage. When a request for the same content is received, the server retrieves the cached version instead of regenerating the content. This process involves several components:
Cache Storage: The physical or virtual storage where cached data is saved. Cache Key: A unique identifier for each cache entry, ensuring the correct data is retrieved. Cache Expiry: The duration for which the cached data is considered valid. Cache Invalidation: The process of removing or updating outdated cache entries.
