- * Create a cache session

- * A cache session represents a client's access into the cache. The cache
- * session is not "owned" by the cache service. Hence, it is possible to
- * create duplicate cache sessions. Entries created by a cache session
- * are invisible to other cache sessions, unless the cache sessions are
- * equivalent.
- *
- * @param clientID - Specifies the name of the client using the cache.
- * @param storagePolicy - Limits the storage policy for all entries
- * accessed via the returned session. As a result, devices excluded
- * by the storage policy will not be searched when opening entries
- * from the returned session.
- * @param streamBased - Indicates whether or not the data being cached
- * can be represented as a stream. The storagePolicy must be
- * consistent with the value of this field. For example, a non-stream-
- * based cache entry can only have a storage policy of STORE_IN_MEMORY.
- * @return new cache session.
