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 specified object based on the header values in viewer requests. 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 cache your content based on values in the Product header. CloudFront forwards the Product 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 How CloudFront Forwards and Caches Headers in the Amazon CloudFront Developer Guide.
