// `CacheSettings` is a property of the [AWS::Lightsail::Distribution](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-lightsail-distribution.html) resource. It describes the cache settings of an Amazon Lightsail content delivery network (CDN) distribution.
//
// These settings apply only to your distribution’s `CacheBehaviors` that have a `Behavior` of `cache` . This includes the `DefaultCacheBehavior` .
//
// Example:
//   // The code below shows an example of how to instantiate this type.
//   // The values are placeholders you should change.

	// The HTTP methods that are processed and forwarded to the distribution's origin.
	//
	// You can specify the following options:
	//
	// - `GET,HEAD` - The distribution forwards the `GET` and `HEAD` methods.
	// - `GET,HEAD,OPTIONS` - The distribution forwards the `GET` , `HEAD` , and `OPTIONS` methods.
	// - `GET,HEAD,OPTIONS,PUT,PATCH,POST,DELETE` - The distribution forwards the `GET` , `HEAD` , `OPTIONS` , `PUT` , `PATCH` , `POST` , and `DELETE` methods.
	//
	// If you specify `GET,HEAD,OPTIONS,PUT,PATCH,POST,DELETE` , you might need to restrict access to your distribution's origin so users can't perform operations that you don't want them to. For example, you might not want users to have permission to delete objects from your origin.
