    • Method Detail

      • callerReference

        public final String callerReference()

        A unique value (for example, a date-time stamp) that ensures that the request can't be replayed.

        If the value of CallerReference is new (regardless of the content of the DistributionConfig object), CloudFront creates a new distribution.

        If CallerReference is a value that you already sent in a previous request to create a distribution, CloudFront returns a DistributionAlreadyExists error.

        Returns:
        A unique value (for example, a date-time stamp) that ensures that the request can't be replayed.

        If the value of CallerReference is new (regardless of the content of the DistributionConfig object), CloudFront creates a new distribution.

        If CallerReference is a value that you already sent in a previous request to create a distribution, CloudFront returns a DistributionAlreadyExists error.

      • httpVersion

        public final HttpVersion httpVersion()

        (Optional) Specify the maximum HTTP version(s) that you want viewers to use to communicate with CloudFront. The default value for new web distributions is http2. Viewers that don't support HTTP/2 automatically use an earlier HTTP version.

        For viewers and CloudFront to use HTTP/2, viewers must support TLSv1.2 or later, and must support Server Name Indication (SNI).

        For viewers and CloudFront to use HTTP/3, viewers must support TLSv1.3 and Server Name Indication (SNI). CloudFront supports HTTP/3 connection migration to allow the viewer to switch networks without losing connection. For more information about connection migration, see Connection Migration at RFC 9000. For more information about supported TLSv1.3 ciphers, see Supported protocols and ciphers between viewers and CloudFront.

        If the service returns an enum value that is not available in the current SDK version, httpVersion will return HttpVersion.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from httpVersionAsString().

      • isIPV6Enabled

        public final Boolean isIPV6Enabled()

        If you want CloudFront to respond to IPv6 DNS requests with an IPv6 address for your distribution, specify true. If you specify false, CloudFront responds to IPv6 DNS requests with the DNS response code NOERROR and with no IP addresses. This allows viewers to submit a second request, for an IPv4 address for your distribution.

        In general, you should enable IPv6 if you have users on IPv6 networks who want to access your content. However, if you're using signed URLs or signed cookies to restrict access to your content, and if you're using a custom policy that includes the IpAddress parameter to restrict the IP addresses that can access your content, don't enable IPv6. If you want to restrict access to some content by IP address and not restrict access to other content (or restrict access but not by IP address), you can create two distributions. For more information, see Creating a Signed URL Using a Custom Policy in the Amazon CloudFront Developer Guide.

        If you're using an Route 53 Amazon Web Services Integration alias resource record set to route traffic to your CloudFront distribution, you need to create a second alias resource record set when both of the following are true:

        • You enable IPv6 for the distribution

        • You're using alternate domain names in the URLs for your objects

        For more information, see Routing Traffic to an Amazon CloudFront Web Distribution by Using Your Domain Name in the Route 53 Amazon Web Services Integration Developer Guide.

        If you created a CNAME resource record set, either with Route 53 Amazon Web Services Integration or with another DNS service, you don't need to make any changes. A CNAME record will route traffic to your distribution regardless of the IP address format of the viewer request.

        Returns:
        If you want CloudFront to respond to IPv6 DNS requests with an IPv6 address for your distribution, specify true. If you specify false, CloudFront responds to IPv6 DNS requests with the DNS response code NOERROR and with no IP addresses. This allows viewers to submit a second request, for an IPv4 address for your distribution.

        In general, you should enable IPv6 if you have users on IPv6 networks who want to access your content.
