   * <p>A complex type that specifies the headers that you want CloudFront to forward
   * to the origin for this cache behavior.</p> <p>For the headers that you specify,
   * CloudFront also caches separate versions of a specified object based on the
   * header values in viewer requests. For example, suppose viewer requests for
   * <code>logo.jpg</code> contain a custom <code>Product</code> header that has a
   * value of either <code>Acme</code> or <code>Apex</code>, and you configure
   * CloudFront to cache your content based on values in the <code>Product</code>
   * header. CloudFront forwards the <code>Product</code> header to the origin and
   * caches the response from the origin once for each header value. For more
   * information about caching based on header values, see <a
   * href="http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/header-caching.html">How
