defaultTTL property
The default amount of time that you want objects to stay in CloudFront
caches before CloudFront forwards another request to your origin to
determine whether the object has been updated. The value that you specify
applies only when your origin does not add HTTP headers such as
Cache-Control max-age, Cache-Control s-maxage, and
Expires to objects. For more information, see Specifying
How Long Objects and Errors Stay in a CloudFront Edge Cache (Expiration)
in the Amazon CloudFront Developer Guide.
