 * ContentCache is a class that provides a way to cache content either in memory or in a file.

 * <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>

For example, if you want to read or manipulate the request body before it is processed by your application.
