 * It implements the Closeable interface to ensure that resources are properly released.
 *
 * <p>This class supports two types of content caching:
 * <ul>
 *   <li>In-memory caching using a byte array</li>
 *   <li>File-based caching using a File object</li>
 * </ul>
 *
 * <p>When an instance of ContentCache is created with a byte array, the content is cached in memory.

        assertTrue(DirectoryLeaseState.canCacheEnumeration(DirectoryLeaseState.DIRECTORY_FULL));

        // Should return false when read caching is not enabled

- Support for query parameters, headers, body (String or stream), compression, SSL configuration, proxies, and timeouts
- Automatic in-memory or on-disk caching of request/response bodies
- Synchronous and asynchronous (callback) execution
- Minimal dependencies (only Apache Commons IO)

- [ ] Implement directory metadata caching
- [ ] Add directory change notification integration
- [ ] Create parent-child lease relationships
- [ ] Implement directory lease break handling
- [ ] Add directory enumeration caching

#### 4.3 Integration Points
- Extend `SmbFile` for directory lease support
- Modify directory listing operations for caching
- Update change notification handling
