HeaderObject

Describes the request headers that a Lightsail distribution bases caching on.

For the headers that you specify, your distribution caches separate versions of the specified content 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 your distribution to cache your content based on values in the product header. Your distribution forwards the product header to the origin and caches the response from the origin once for each header value.
