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
     }
   ]
 }
