//
// To create a new web distribution, submit a POST request to the CloudFront
// API version/distribution resource. The request body must include a document
// with a StreamingDistributionConfig element. The response echoes the StreamingDistributionConfig
// element and returns other information about the RTMP distribution.
//
// To get the status of your request, use the GET StreamingDistribution API
// action. When the value of Enabled is true and the value of Status is Deployed,
// your distribution is ready. A distribution usually deploys in less than 15
// minutes.
//

//
// Beginning with the 2012-05-05 version of the CloudFront API, we made substantial
// changes to the format of the XML document that you include in the request
// body when you create or update a web distribution or an RTMP distribution,
// and when you invalidate objects. With previous versions of the API, we discovered
// that it was too easy to accidentally delete one or more values for an element
// that accepts multiple values, for example, CNAMEs and trusted signers. Our

// To update a web distribution using the CloudFront API
//
// Submit a GetDistributionConfig request to get the current configuration and
// an Etag header for the distribution.
//
// If you update the distribution again, you need to get a new Etag header.
//
// Update the XML document that was returned in the response to your GetDistributionConfig
// request to include the desired changes. You can't change the value of CallerReference.
// If you try to change this value, CloudFront returns an IllegalUpdate error.
//
// The new configuration replaces the existing configuration; the values that
// you specify in an UpdateDistribution request are not merged into the existing
// configuration. When you add, delete, or replace values in an element that
// allows multiple values (for example, CNAME), you must specify all of the
// values that you want to appear in the updated distribution. In addition,
// you must update the corresponding Quantity element.
//
// Submit an UpdateDistribution request to update the configuration for your
// distribution:
//
// In the request body, include the XML document that you updated in Step 2.
// The request body must include an XML document with a DistributionConfig element.
//
// Set the value of the HTTP If-Match header to the value of the ETag header
// that CloudFront returned when you submitted the GetDistributionConfig request
// in Step 1.
//
// Review the response to the UpdateDistribution request to confirm that the
// configuration was successfully updated.
//
// Optional: Submit a GetDistribution request to confirm that your changes have
// propagated. When propagation is complete, the value of Status is Deployed.
//
// Beginning with the 2012-05-05 version of the CloudFront API, we made substantial
// changes to the format of the XML document that you include in the request
// body when you create or update a distribution. With previous versions of
// the API, we discovered that it was too easy to accidentally delete one or
// more values for an element that accepts multiple values, for example, CNAMEs
// and trusted signers. Our changes for the 2012-05-05 release are intended
// to prevent these accidental deletions and to notify you when there's a mismatch

	// 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

	//    the HTTPS URL. The viewer then resubmits the request using the new URL.

	// your origin returned to CloudFront, for example:
	//
	//    * Some Internet devices (some firewalls and corporate proxies, for example)
	//    intercept HTTP 4xx and 5xx and prevent the response from being returned
	//    to the viewer. If you substitute 200, the response typically won't be

	//
	//    * If you don't care about distinguishing among different client errors
	//    or server errors, you can specify 400 or 500 as the ResponseCode for all
	//    4xx or 5xx errors.
	//
	//    * You might want to return a 200 status code (OK) and static website so
	//    your customers don't know that your website is down.
	//
	// If you specify a value for ResponseCode, you must also specify a value for

	// and your custom error pages in different locations, your distribution must
	// include a cache behavior for which the following is true:
	//
	//    * The value of PathPattern matches the path to your custom error messages.
	//    For example, suppose you saved custom error pages for 4xx errors in an
	//    Amazon S3 bucket in a directory named /4xx-errors. Your distribution must

	// for ResponseCode. If you don't want to specify a value, include an empty
	// element, <ResponsePagePath>, in the XML document.
	//
	// We recommend that you store custom error pages in an Amazon S3 bucket. If

	//    domain name such as example.com or the CloudFront domain name for your
	//    distribution, such as d111111abcdef8.cloudfront.net.
	//
	//    * If you're using an alternate domain name, whether AWS Certificate Manager
	//    (ACM) provided the certificate, or you purchased a certificate from a
	//    third-party certificate authority and imported it into ACM or uploaded
	//    it to the IAM certificate store.

	//
	// <CloudFrontDefaultCertificate>true<CloudFrontDefaultCertificate>
	//
	// In addition, specify allow-all for ViewerProtocolPolicy for all of your cache
	// behaviors.
	//
	// If you want viewers to use HTTPS to request your objects: Choose the type
	// of certificate that you want to use based on whether you're using an alternate
	// domain name for your objects or the CloudFront domain name:
	//
	//    * If you're using an alternate domain name, such as example.com: Specify
	//    one of the following values, depending on whether ACM provided your certificate
	//    or you purchased your certificate from third-party certificate authority:
	//
	// <ACMCertificateArn>ARN for ACM SSL/TLS certificate<ACMCertificateArn> where
	//    ARN for ACM SSL/TLS certificate is the ARN for the ACM SSL/TLS certificate
	//    that you want to use for this distribution.
	//
	// <IAMCertificateId>IAM certificate ID<IAMCertificateId> where IAM certificate
	//    ID is the ID that IAM returned when you added the certificate to the IAM
	//    certificate store.
	//
	// If you specify ACMCertificateArn or IAMCertificateId, you must also specify
	//    a value for SSLSupportMethod.
	//
	// If you choose to use an ACM certificate or a certificate in the IAM certificate
	//    store, we recommend that you use only an alternate domain name in your
	//    object URLs (https://example.com/logo.jpg). If you use the domain name
	//    that is associated with your CloudFront distribution (such as https://d111111abcdef8.cloudfront.net/logo.jpg)
	//    and the viewer supports SNI, then CloudFront behaves normally. However,
	//    if the browser does not support SNI, the user's experience depends on
	//    the value that you choose for SSLSupportMethod:
	//
	// vip: The viewer displays a warning because there is a mismatch between the
	//    CloudFront domain name and the domain name in your SSL/TLS certificate.
	//
	// sni-only: CloudFront drops the connection with the browser without returning
	//    the object.
	//
	//    * If you're using the CloudFront domain name for your distribution, such
	//    as d111111abcdef8.cloudfront.net: Specify the following value:
	//
	// <CloudFrontDefaultCertificate>true<CloudFrontDefaultCertificate>
	//
	// If you want viewers to use HTTPS, you must also specify one of the following
	// values in your cache behaviors:
	//
	//    *  <ViewerProtocolPolicy>https-only<ViewerProtocolPolicy>
	//
	//    * <ViewerProtocolPolicy>redirect-to-https<ViewerProtocolPolicy>
	//
	// You can also optionally require that CloudFront use HTTPS to communicate
	// with your origin by specifying one of the following values for the applicable
	// origins:
	//
	//    * <OriginProtocolPolicy>https-only<OriginProtocolPolicy>
	//
	//    * <OriginProtocolPolicy>match-viewer<OriginProtocolPolicy>

	//    domain name such as example.com or the CloudFront domain name for your
	//    distribution, such as d111111abcdef8.cloudfront.net.
	//
	//    * If you're using an alternate domain name, whether AWS Certificate Manager
	//    (ACM) provided the certificate, or you purchased a certificate from a
	//    third-party certificate authority and imported it into ACM or uploaded
	//    it to the IAM certificate store.
	//
	// You must specify only one of the following values:
	//
	//    * ViewerCertificate$ACMCertificateArn
	//
	//    * ViewerCertificate$IAMCertificateId
	//
	//    * ViewerCertificate$CloudFrontDefaultCertificate

	//
	// <CloudFrontDefaultCertificate>true<CloudFrontDefaultCertificate>
	//
	// In addition, specify allow-all for ViewerProtocolPolicy for all of your cache
	// behaviors.
	//
	// If you want viewers to use HTTPS to request your objects: Choose the type
	// of certificate that you want to use based on whether you're using an alternate
	// domain name for your objects or the CloudFront domain name:
	//
	//    * If you're using an alternate domain name, such as example.com: Specify
	//    one of the following values, depending on whether ACM provided your certificate
	//    or you purchased your certificate from third-party certificate authority:
	//
	// <ACMCertificateArn>ARN for ACM SSL/TLS certificate<ACMCertificateArn> where
	//    ARN for ACM SSL/TLS certificate is the ARN for the ACM SSL/TLS certificate
	//    that you want to use for this distribution.
	//
	// <IAMCertificateId>IAM certificate ID<IAMCertificateId> where IAM certificate
	//    ID is the ID that IAM returned when you added the certificate to the IAM
	//    certificate store.
	//
	// If you specify ACMCertificateArn or IAMCertificateId, you must also specify
	//    a value for SSLSupportMethod.
	//
	// If you choose to use an ACM certificate or a certificate in the IAM certificate
	//    store, we recommend that you use only an alternate domain name in your
	//    object URLs (https://example.com/logo.jpg). If you use the domain name
	//    that is associated with your CloudFront distribution (such as https://d111111abcdef8.cloudfront.net/logo.jpg)
	//    and the viewer supports SNI, then CloudFront behaves normally. However,
	//    if the browser does not support SNI, the user's experience depends on
	//    the value that you choose for SSLSupportMethod:
	//
	// vip: The viewer displays a warning because there is a mismatch between the
	//    CloudFront domain name and the domain name in your SSL/TLS certificate.
	//
	// sni-only: CloudFront drops the connection with the browser without returning
	//    the object.
	//
	//    * If you're using the CloudFront domain name for your distribution, such
	//    as d111111abcdef8.cloudfront.net: Specify the following value:
	//
	// <CloudFrontDefaultCertificate>true<CloudFrontDefaultCertificate>
	//
	// If you want viewers to use HTTPS, you must also specify one of the following
	// values in your cache behaviors:
	//
	//    *  <ViewerProtocolPolicy>https-only<ViewerProtocolPolicy>
	//
	//    * <ViewerProtocolPolicy>redirect-to-https<ViewerProtocolPolicy>
	//
	// You can also optionally require that CloudFront use HTTPS to communicate
	// with your origin by specifying one of the following values for the applicable
	// origins:
	//
	//    * <OriginProtocolPolicy>https-only<OriginProtocolPolicy>

//    * Whether you want viewers to use HTTP or HTTPS to request your objects.
//
//    * If you want viewers to use HTTPS, whether you're using an alternate
//    domain name such as example.com or the CloudFront domain name for your
//    distribution, such as d111111abcdef8.cloudfront.net.
//
//    * If you're using an alternate domain name, whether AWS Certificate Manager
//    (ACM) provided the certificate, or you purchased a certificate from a
//    third-party certificate authority and imported it into ACM or uploaded
//    it to the IAM certificate store.
//
// You must specify only one of the following values:
//
//    * ViewerCertificate$ACMCertificateArn
//
//    * ViewerCertificate$IAMCertificateId
//
//    * ViewerCertificate$CloudFrontDefaultCertificate
//
// Don't specify false for CloudFrontDefaultCertificate.
//
// If you want viewers to use HTTP instead of HTTPS to request your objects:
// Specify the following value:
//
// <CloudFrontDefaultCertificate>true<CloudFrontDefaultCertificate>
//
// In addition, specify allow-all for ViewerProtocolPolicy for all of your cache
// behaviors.
//
// If you want viewers to use HTTPS to request your objects: Choose the type
// of certificate that you want to use based on whether you're using an alternate
// domain name for your objects or the CloudFront domain name:
//
//    * If you're using an alternate domain name, such as example.com: Specify
//    one of the following values, depending on whether ACM provided your certificate
//    or you purchased your certificate from third-party certificate authority:
//
// <ACMCertificateArn>ARN for ACM SSL/TLS certificate<ACMCertificateArn> where
//    ARN for ACM SSL/TLS certificate is the ARN for the ACM SSL/TLS certificate
//    that you want to use for this distribution.
//
// <IAMCertificateId>IAM certificate ID<IAMCertificateId> where IAM certificate
//    ID is the ID that IAM returned when you added the certificate to the IAM
//    certificate store.
//
// If you specify ACMCertificateArn or IAMCertificateId, you must also specify
//    a value for SSLSupportMethod.
//
// If you choose to use an ACM certificate or a certificate in the IAM certificate
//    store, we recommend that you use only an alternate domain name in your
//    object URLs (https://example.com/logo.jpg). If you use the domain name
//    that is associated with your CloudFront distribution (such as https://d111111abcdef8.cloudfront.net/logo.jpg)
//    and the viewer supports SNI, then CloudFront behaves normally. However,
//    if the browser does not support SNI, the user's experience depends on
//    the value that you choose for SSLSupportMethod:
//
// vip: The viewer displays a warning because there is a mismatch between the
//    CloudFront domain name and the domain name in your SSL/TLS certificate.
//
// sni-only: CloudFront drops the connection with the browser without returning
//    the object.
//
//    * If you're using the CloudFront domain name for your distribution, such
//    as d111111abcdef8.cloudfront.net: Specify the following value:
//
// <CloudFrontDefaultCertificate>true<CloudFrontDefaultCertificate>
//
// If you want viewers to use HTTPS, you must also specify one of the following
// values in your cache behaviors:
//
//    *  <ViewerProtocolPolicy>https-only<ViewerProtocolPolicy>
//
//    * <ViewerProtocolPolicy>redirect-to-https<ViewerProtocolPolicy>
//
// You can also optionally require that CloudFront use HTTPS to communicate
// with your origin by specifying one of the following values for the applicable
// origins:
//
//    * <OriginProtocolPolicy>https-only<OriginProtocolPolicy>
//
//    * <OriginProtocolPolicy>match-viewer<OriginProtocolPolicy>

	//
	//    * The cipher that CloudFront uses to encrypt the content that it returns
	//    to viewers
	//
	// On the CloudFront console, this setting is called Security policy.
	//
	// We recommend that you specify TLSv1.1_2016 unless your users are using browsers
	// or devices that do not support TLSv1.1 or later.
	//
	// When both of the following are true, you must specify TLSv1 or later for
	// the security policy:
	//
	//    * You're using a custom certificate: you specified a value for ACMCertificateArn
	//    or for IAMCertificateId
	//
	//    * You're using SNI: you specified sni-only for SSLSupportMethod
	//
	// If you specify true for CloudFrontDefaultCertificate, CloudFront automatically

	// If you specify a value for ViewerCertificate$ACMCertificateArn or for ViewerCertificate$IAMCertificateId,

	//
	//    * vip: CloudFront uses dedicated IP addresses for your content and can
	//    respond to HTTPS requests from any viewer. However, you will incur additional
	//    monthly charges.
	//
	//    * sni-only: CloudFront can respond to HTTPS requests from viewers that
	//    support Server Name Indication (SNI). All modern browsers support SNI,
	//    but some browsers still in use don't support SNI. If some of your users'
	//    browsers don't support SNI, we recommend that you do one of the following:
	//
	// Use the vip option (dedicated IP addresses) instead of sni-only.
	//
	// Use the CloudFront SSL/TLS certificate instead of a custom certificate. This
	//    requires that you use the CloudFront domain name of your distribution
	//    in the URLs for your objects, for example, https://d111111abcdef8.cloudfront.net/logo.png.
	//
	// If you can control which browser your users use, upgrade the browser to one
	//    that supports SNI.
