The default cache manager also adds the following headers to cached responses: | ||
* `X-Local-Cache`: Path to the cache the content was found in | ||
* `X-Local-Cache-Key`: Unique cache entry key for this response | ||
* `X-Local-Cache-Hash`: Specific integrity hash for the cached entry | ||
* `X-Local-Cache-Time`: UTCString of the cache insertion time for the entry | ||
Using [`cacache`](https://npm.im/cacache), a call like this may be used to | ||
manually fetch the cached entry: | ||
```javascript | ||
const h = response.headers | ||
cacache.get(h.get('x-local-cache'), h.get('x-local-cache-key')) | ||
// grab content only, directly: | ||
cacache.get.byDigest(h.get('x-local-cache'), h.get('x-local-cache-hash')) | ||
``` | ||
