/**
 * <p>
 * A cache policy.
 * </p>
 * <p>
 * When it's attached to a cache behavior, the cache policy determines the following:
 * </p>
 * <ul>
 * <li>
 * <p>
 * The values that CloudFront includes in the cache key. These values can include HTTP headers, cookies, and URL query
 * strings. CloudFront uses the cache key to find an object in its cache that it can return to the viewer.
 * </p>
 * </li>
 * <li>
 * <p>
 * The default, minimum, and maximum time to live (TTL) values that you want objects to stay in the CloudFront cache.
 * </p>
 * </li>
 * </ul>
 * <p>
 * The headers, cookies, and query strings that are included in the cache key are also included in requests that
 * CloudFront sends to the origin. CloudFront sends a request when it can't find a valid object in its cache that
 * matches the request's cache key. If you want to send values to the origin but <i>not</i> include them in the cache
 * key, use <code>OriginRequestPolicy</code>.
