# flushCache()

Flushes all cached data, such as TLS session state, created by connections associated with the privacy context.

## Declaration

```swift
func flushCache()
```

## Discussion

Discussion Flushing the cache may be asynchronous, which means that it will take effect shortly after you invoke the function.
