Deleting the cache when it is no longer needed can be done.  However this may delete the purpose of the cache
which is designed to persist between app restarts.

```kotlin
cache.delete()
```
 
## Pruning the Cache

Pruning the entire Cache to clear space temporarily can be done using evictAll.

```kotlin
cache.evictAll()
```

Removing individual items can be done using the urls iterator.

	response, err = x.ClientConversation.Step(challenge)
	return response, err
}

// Done returns true if the conversation is completed or has errored.
func (x *XDGSCRAMClient) Done() bool {
	return x.ClientConversation.Done()

		go func(ctx context.Context, peerChannel <-chan MetricV2, wg *sync.WaitGroup) {
			defer wg.Done()
			for {
				select {
				case m, ok := <-peerChannel:
					if !ok {
						return
					}
					select {
					case ch <- m:
					case <-ctx.Done():
						return
					}
				case <-ctx.Done():
					return
				}
			}
		}(ctx, peerChannels[index], &wg)
