A complex type that specifies the headers that you want CloudFront to forward to the origin for this cache behavior. For the headers that you specify, CloudFront also caches separate versions of a given object based on the header values in viewer requests; this is known as varying on headers. For example, suppose viewer requests for logo.jpg contain a custom Product header that has a value of either Acme or Apex, and you configure CloudFront to vary on the Product header. CloudFront forwards the Product header to the origin and caches the response from the origin once for each header value.

 
 public class Headers implements SerializableCloneable {

    
The number of different headers that you want CloudFront to forward to the origin and to vary on for this cache behavior. The maximum number of headers that you can specify by name is 10. If you want CloudFront to forward all headers to the origin and vary on all of them, specify 1 for Quantity and * for Name. If you don't want CloudFront to forward any additional headers to the origin or to vary on any headers, specify 0 for Quantity and omit Items.
 
     private Integer quantity;

    
Optional: A complex type that contains a Name element for each header that you want CloudFront to forward to the origin and to vary on for this cache behavior. If Quantity is 0, omit Items.
