# NSURLRequest.CachePolicy.returnCacheDataDontLoad

Use existing cache data, regardless or age or expiration date, and fail if no cached data is available.

## Declaration

```swift
case returnCacheDataDontLoad
```

## Mentioned in

Accessing cached data

## Discussion

Discussion If there is no existing data in the cache corresponding to a URL load request, no attempt is made to load the data from the originating source, and the load is considered to have failed. This constant specifies a behavior that is similar to an “offline” mode.
