# Class CacheMgr

## Inheritance Hierarchy

- Object
  - dw.system.CacheMgr

## Description

The CacheMgr class is the entry point for using custom caches. The CacheMgr can manage multiple custom caches that share one storage space. Each individual cache has a unique ID and an optional expiration time that specifies the maximum time (in seconds) an entry is stored in the cache. For registering caches inside the cartridge root folder, a 'package.json' file with a 'caches' entry must exist. The registration of caches is independent of any site context. "caches": "./caches.json" The caches entry links to a JSON file, with a path relative to the 'package.json' file. This file lists all registered caches inside the caches property: { "caches": [ { "id": "UnlimitedTestCache" }, { "id": "TestCacheWithExpiration", "expireAfterSeconds": 10 } ] }
