However, this means that STS tokens signed previously by root credentials will no longer be valid upon upgrading to the latest version with this change. Please re-generate them as you usually do. Additionally, if site replication is ever removed - the STS...

## Cache directory

The cache directory must be exclusively owned by a single instance.

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

   * <p>Historically, {@code Supplier} instances in this library have implemented this method to

   * disappear. It is best not to depend on it.
