Properties

NameTypeDescription
Public Property AllowedMethods Amazon.CloudFront.Model.AllowedMethods Gets and sets the property AllowedMethods.
Public Property DefaultTTL System.Int64 Gets and sets the property DefaultTTL. If you don't configure your origin to add a Cache-Control max-age directive or an Expires header, DefaultTTL is the default amount of time (in seconds) that an object is in a CloudFront cache 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. You can specify a value from 0 to 3,153,600,000 seconds (100 years).
Public Property ForwardedValues Amazon.CloudFront.Model.ForwardedValues Gets and sets the property ForwardedValues. A complex type that specifies how CloudFront handles query strings, cookies and headers.
Public Property MaxTTL System.Int64 Gets and sets the property MaxTTL. The maximum amount of time (in seconds) that an object is in a CloudFront cache 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 adds HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. You can specify a value from 0 to 3,153,600,000 seconds (100 years).
Public Property MinTTL System.Int64 Gets and sets the property MinTTL. The minimum amount of time that you want objects to stay in CloudFront caches before CloudFront queries your origin to see whether the object has been updated.You can specify a value from 0 to 3,153,600,000 seconds (100 years).
Public Property SmoothStreaming System.Boolean Gets and sets the property SmoothStreaming. Indicates whether you want to distribute media files in Microsoft Smooth Streaming format using the origin that is associated with this cache behavior. If so, specify true; if not, specify false.
Public Property TargetOriginId System.String Gets and sets the property TargetOriginId. 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.
Public Property TrustedSigners Amazon.CloudFront.Model.TrustedSigners Gets and sets the property 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, go to Using a Signed URL to Serve Private Content in the 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.
Public Property ViewerProtocolPolicy Amazon.CloudFront.ViewerProtocolPolicy Gets and sets the property ViewerProtocolPolicy. Use this element to specify the protocol that users can use to access the files in the origin specified by TargetOriginId when a request matches the path pattern in PathPattern. If you want CloudFront to allow end users to use any available protocol, specify allow-all. If you want CloudFront to require HTTPS, specify https. If you want CloudFront to respond to an HTTP request with an HTTP status code of 301 (Moved Permanently) and the HTTPS URL, specify redirect-to-https. The viewer then resubmits the request using the HTTPS URL.
