A complex type that describes the default cache behavior if you do not specify a ‘CacheBehavior` element or if files don’t match any of the values of ‘PathPattern` in `CacheBehavior` elements. You must create exactly one default cache behavior.

Instance Attribute Details
#allowed_methods ⇒ Types::AllowedMethods
A complex type that controls which HTTP methods CloudFront processes and forwards to your Amazon S3 bucket or your custom origin. There are three choices:
-
CloudFront forwards only ‘GET` and `HEAD` requests.
-
CloudFront forwards only ‘GET`, `HEAD`, and `OPTIONS` requests.
-
CloudFront forwards ‘GET, HEAD, OPTIONS, PUT, PATCH, POST`, and `DELETE` requests.
If you pick the third choice, you may need to restrict access to your Amazon S3 bucket or to your custom origin so users can’t perform operations that you don’t want them to. For example, you might not want users to have permissions to delete objects from your origin.

#default_ttl ⇒ Integer
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.

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 [Specifying How Long Objects and Errors Stay in a CloudFront Edge Cache (Expiration)] in the *Amazon 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`).

#smooth_streaming ⇒ Boolean
Indicates whether you want to distribute media files in the Microsoft Smooth Streaming format using the origin that is associated with this cache behavior. If so, specify ‘true`; if not, specify `false`. If you specify `true` for `SmoothStreaming`, you can still distribute other content using this cache behavior if the content matches the value of `PathPattern`.

#target_origin_id ⇒ String
The value of ‘ID` for the origin that you want CloudFront to route requests to when a request matches the path pattern either for a cache behavior or for the default cache behavior.
2015 2016 2017 2018 2019 2020 2021 2022 2023 2024 2025 2026 2027 2028 |

#trusted_signers ⇒ Types::TrustedSigners
A complex type that specifies the AWS accounts, if any, that you want to allow to create signed URLs for private content.
If you want to require signed URLs in requests for objects in the target origin that match the ‘PathPattern` for this cache behavior, specify `true` for `Enabled`, and specify the applicable values for `Quantity` and `Items`. For more information, see [Serving Private Content through CloudFront] in the *Amazon Amazon CloudFront Developer Guide*.
If you don’t want to require signed URLs in requests for objects that match ‘PathPattern`, specify `false` for `Enabled` and `0` for `Quantity`. Omit `Items`.
To add, change, or remove one or more trusted signers, change ‘Enabled` to `true` (if it’s currently ‘false`), change `Quantity` as applicable, and specify all of the trusted signers that you want to include in the updated distribution.

# File 'lib/aws-sdk-cloudfront/types.rb', line 2015 class DefaultCacheBehavior < Struct.new( :target_origin_id, :forwarded_values, :trusted_signers, :viewer_protocol_policy, :min_ttl, :allowed_methods, :smooth_streaming, :default_ttl, :max_ttl, :compress, :lambda_function_associations) include Aws::Structure end |
#viewer_protocol_policy ⇒ String
The protocol that viewers can use to access the files in the origin specified by ‘TargetOriginId` when a request matches the path pattern in `PathPattern`. You can specify the following options:
-
‘allow-all`: Viewers can use HTTP or HTTPS.
-
‘redirect-to-https`: If a viewer submits an HTTP request, CloudFront returns an HTTP status code of 301 (Moved Permanently) to the viewer along with the HTTPS URL. The viewer then resubmits the request using the new URL.
-
‘https-only`: If a viewer sends an HTTP request, CloudFront returns an HTTP status code of 403 (Forbidden).
For more information about requiring the HTTPS protocol, see [Using an HTTPS Connection to Access Your Objects] in the *Amazon CloudFront Developer Guide*.
<note markdown=“1”> The only way to guarantee that viewers retrieve an object that was fetched from the origin using HTTPS is never to use any other protocol to fetch the object. If you have recently changed from HTTP to HTTPS, we recommend that you clear your objects’ cache because cached objects are protocol agnostic. That means that an edge location will return an object from the cache regardless of whether the current request protocol matches the protocol used previously. For more information, see [Specifying How Long Objects and Errors Stay in a CloudFront Edge Cache (Expiration)] in the *Amazon CloudFront Developer Guide*.
