minTtl

This field is deprecated. We recommend that you use the `MinTTL` field in a cache policy instead of this field. For more information, see Creating cache policies or Using the managed cache policies in the Amazon CloudFront Developer Guide. The minimum 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. For more information, see Managing How Long Content Stays in an Edge Cache (Expiration) in the Amazon CloudFront Developer Guide. You must specify `0` for `MinTTL` if you configure CloudFront to forward all headers to your origin (under `Headers`, if you specify `1` for `Quantity` and `*` for `Name`).
