Overview

Package proxycache registers the "proxycache" blobserver storage type, which uses a provided blobserver as a cache for a second origin blobserver.

The proxycache blobserver type also takes a sorted.KeyValue reference which it uses as the LRU for which old items to evict from the cache.

Example config:

      "/cache/": {
          "handler": "storage-proxycache",
          "handlerArgs": {
		  "origin": "",
		  "cache": "",
		  "meta": {},
		  "maxCacheBytes": 536870912
          }
      },
