Amazon CloudFront Construct Library

Amazon CloudFront is a web service that speeds up distribution of your static and dynamic web content, such as .html, .css, .js, and image files, to your users. CloudFront delivers your content through a worldwide network of data centers called edge locations. When a user requests content that you're serving with CloudFront, the user is routed to the edge location that provides the lowest latency, so that content is delivered with the best possible performance.

Distribution API

The Distribution API is currently being built to replace the existing CloudFrontWebDistribution API. The Distribution API is optimized for the most common use cases of CloudFront distributions (e.g., single origin and behavior, few customizations) while still providing the ability for more advanced use cases. The API focuses on simplicity for the common use cases, and convenience methods for creating the behaviors and origins necessary for more complex use cases.

Creating a distribution

CloudFront distributions deliver your content from one or more origins; an origin is the location where you store the original version of your content. Origins can be created from S3 buckets or a custom origin (HTTP server). Constructs to define origins are in the @aws-cdk/aws-cloudfront-origins module.

Each distribution has a default behavior which applies to all requests to that distribution, and routes requests to a primary origin. Additional behaviors may be specified for an origin with a given URL path pattern. Behaviors allow routing with multiple origins, controlling which HTTP methods to support, whether to require users to use HTTPS, and what query strings or cookies to forward to your origin, among other settings.

From an S3 Bucket

An S3 bucket can be added as an origin. If the bucket is configured as a website endpoint, the distribution can use S3 redirects and S3 custom error documents.

// Creates a distribution from an S3 bucket.
myBucket := s3.NewBucket(this, jsii.String("myBucket"))
cloudfront.NewDistribution(this, jsii.String("myDist"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: origins.NewS3Origin(myBucket),
	},
})

The above will treat the bucket differently based on if IBucket.isWebsite is set or not. If the bucket is configured as a website, the bucket is treated as an HTTP origin, and the built-in S3 redirects and error pages can be used. Otherwise, the bucket is handled as a bucket origin and CloudFront's redirect and error handling will be used. In the latter case, the Origin will create an origin access identity and grant it access to the underlying bucket. This can be used in conjunction with a bucket that is not public to require that your users access your content using CloudFront URLs and not S3 URLs directly.

ELBv2 Load Balancer

An Elastic Load Balancing (ELB) v2 load balancer may be used as an origin. In order for a load balancer to serve as an origin, it must be publicly accessible (internetFacing is true). Both Application and Network load balancers are supported.

// Creates a distribution from an ELBv2 load balancer
var vpc vpc

// Create an application load balancer in a VPC. 'internetFacing' must be 'true'
// for CloudFront to access the load balancer and use it as an origin.
lb := elbv2.NewApplicationLoadBalancer(this, jsii.String("LB"), &applicationLoadBalancerProps{
	vpc: vpc,
	internetFacing: jsii.Boolean(true),
})
cloudfront.NewDistribution(this, jsii.String("myDist"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: origins.NewLoadBalancerV2Origin(lb),
	},
})
From an HTTP endpoint

Origins can also be created from any other HTTP endpoint, given the domain name, and optionally, other origin properties.

// Creates a distribution from an HTTP endpoint
// Creates a distribution from an HTTP endpoint
cloudfront.NewDistribution(this, jsii.String("myDist"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: origins.NewHttpOrigin(jsii.String("www.example.com")),
	},
})
Domain Names and Certificates

When you create a distribution, CloudFront assigns a domain name for the distribution, for example: d111111abcdef8.cloudfront.net; this value can be retrieved from distribution.distributionDomainName. CloudFront distributions use a default certificate (*.cloudfront.net) to support HTTPS by default. If you want to use your own domain name, such as www.example.com, you must associate a certificate with your distribution that contains your domain name, and provide one (or more) domain names from the certificate for the distribution.

The certificate must be present in the AWS Certificate Manager (ACM) service in the US East (N. Virginia) region; the certificate may either be created by ACM, or created elsewhere and imported into ACM. When a certificate is used, the distribution will support HTTPS connections from SNI only and a minimum protocol version of TLSv1.2_2021 if the @aws-cdk/aws-cloudfront:defaultSecurityPolicyTLSv1.2_2021 feature flag is set, and TLSv1.2_2019 otherwise.

// To use your own domain name in a Distribution, you must associate a certificate
import acm "github.com/aws/aws-cdk-go/awscdk"
import route53 "github.com/aws/aws-cdk-go/awscdk"

var hostedZone hostedZone

var myBucket bucket

myCertificate := acm.NewDnsValidatedCertificate(this, jsii.String("mySiteCert"), &dnsValidatedCertificateProps{
	domainName: jsii.String("www.example.com"),
	hostedZone: hostedZone,
})
cloudfront.NewDistribution(this, jsii.String("myDist"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: origins.NewS3Origin(myBucket),
	},
	domainNames: []*string{
		jsii.String("www.example.com"),
	},
	certificate: myCertificate,
})

However, you can customize the minimum protocol version for the certificate while creating the distribution using minimumProtocolVersion property.

// Create a Distribution with a custom domain name and a minimum protocol version.
var myBucket bucket

cloudfront.NewDistribution(this, jsii.String("myDist"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: origins.NewS3Origin(myBucket),
	},
	domainNames: []*string{
		jsii.String("www.example.com"),
	},
	minimumProtocolVersion: cloudfront.securityPolicyProtocol_TLS_V1_2016,
	sslSupportMethod: cloudfront.sSLMethod_SNI,
})
Multiple Behaviors & Origins

Each distribution has a default behavior which applies to all requests to that distribution; additional behaviors may be specified for a given URL path pattern. Behaviors allow routing with multiple origins, controlling which HTTP methods to support, whether to require users to use HTTPS, and what query strings or cookies to forward to your origin, among others.

The properties of the default behavior can be adjusted as part of the distribution creation. The following example shows configuring the HTTP methods and viewer protocol policy of the cache.

// Create a Distribution with configured HTTP methods and viewer protocol policy of the cache.
var myBucket bucket

myWebDistribution := cloudfront.NewDistribution(this, jsii.String("myDist"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: origins.NewS3Origin(myBucket),
		allowedMethods: cloudfront.allowedMethods_ALLOW_ALL(),
		viewerProtocolPolicy: cloudfront.viewerProtocolPolicy_REDIRECT_TO_HTTPS,
	},
})

Additional behaviors can be specified at creation, or added after the initial creation. Each additional behavior is associated with an origin, and enable customization for a specific set of resources based on a URL path pattern. For example, we can add a behavior to myWebDistribution to override the default viewer protocol policy for all of the images.

// Add a behavior to a Distribution after initial creation.
var myBucket bucket
var myWebDistribution distribution

myWebDistribution.addBehavior(jsii.String("/images/*.jpg"), origins.NewS3Origin(myBucket), &addBehaviorOptions{
	viewerProtocolPolicy: cloudfront.viewerProtocolPolicy_REDIRECT_TO_HTTPS,
})

These behaviors can also be specified at distribution creation time.

// Create a Distribution with additional behaviors at creation time.
var myBucket bucket

bucketOrigin := origins.NewS3Origin(myBucket)
cloudfront.NewDistribution(this, jsii.String("myDist"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: bucketOrigin,
		allowedMethods: cloudfront.allowedMethods_ALLOW_ALL(),
		viewerProtocolPolicy: cloudfront.viewerProtocolPolicy_REDIRECT_TO_HTTPS,
	},
	additionalBehaviors: map[string]*behaviorOptions{
		"/images/*.jpg": &behaviorOptions{
			"origin": bucketOrigin,
			"viewerProtocolPolicy": cloudfront.*viewerProtocolPolicy_REDIRECT_TO_HTTPS,
		},
	},
})
Customizing Cache Keys and TTLs with Cache Policies

You can use a cache policy to improve your cache hit ratio by controlling the values (URL query strings, HTTP headers, and cookies) that are included in the cache key, and/or adjusting how long items remain in the cache via the time-to-live (TTL) settings. CloudFront provides some predefined cache policies, known as managed policies, for common use cases. You can use these managed policies, or you can create your own cache policy that’s specific to your needs. See https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/controlling-the-cache-key.html for more details.

// Using an existing cache policy for a Distribution
var bucketOrigin s3Origin

cloudfront.NewDistribution(this, jsii.String("myDistManagedPolicy"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: bucketOrigin,
		cachePolicy: cloudfront.cachePolicy_CACHING_OPTIMIZED(),
	},
})

// Creating a custom cache policy for a Distribution -- all parameters optional
var bucketOrigin s3Origin

myCachePolicy := cloudfront.NewCachePolicy(this, jsii.String("myCachePolicy"), &cachePolicyProps{
	cachePolicyName: jsii.String("MyPolicy"),
	comment: jsii.String("A default policy"),
	defaultTtl: awscdk.Duration.days(jsii.Number(2)),
	minTtl: awscdk.Duration.minutes(jsii.Number(1)),
	maxTtl: awscdk.Duration.days(jsii.Number(10)),
	cookieBehavior: cloudfront.cacheCookieBehavior.all(),
	headerBehavior: cloudfront.cacheHeaderBehavior.allowList(jsii.String("X-CustomHeader")),
	queryStringBehavior: cloudfront.cacheQueryStringBehavior.denyList(jsii.String("username")),
	enableAcceptEncodingGzip: jsii.Boolean(true),
	enableAcceptEncodingBrotli: jsii.Boolean(true),
})
cloudfront.NewDistribution(this, jsii.String("myDistCustomPolicy"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: bucketOrigin,
		cachePolicy: myCachePolicy,
	},
})
Customizing Origin Requests with Origin Request Policies

When CloudFront makes a request to an origin, the URL path, request body (if present), and a few standard headers are included. Other information from the viewer request, such as URL query strings, HTTP headers, and cookies, is not included in the origin request by default. You can use an origin request policy to control the information that’s included in an origin request. CloudFront provides some predefined origin request policies, known as managed policies, for common use cases. You can use these managed policies, or you can create your own origin request policy that’s specific to your needs. See https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/controlling-origin-requests.html for more details.

// Using an existing origin request policy for a Distribution
var bucketOrigin s3Origin

cloudfront.NewDistribution(this, jsii.String("myDistManagedPolicy"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: bucketOrigin,
		originRequestPolicy: cloudfront.originRequestPolicy_CORS_S3_ORIGIN(),
	},
})

// Creating a custom origin request policy for a Distribution -- all parameters optional
var bucketOrigin s3Origin

myOriginRequestPolicy := cloudfront.NewOriginRequestPolicy(this, jsii.String("OriginRequestPolicy"), &originRequestPolicyProps{
	originRequestPolicyName: jsii.String("MyPolicy"),
	comment: jsii.String("A default policy"),
	cookieBehavior: cloudfront.originRequestCookieBehavior.none(),
	headerBehavior: cloudfront.originRequestHeaderBehavior.all(jsii.String("CloudFront-Is-Android-Viewer")),
	queryStringBehavior: cloudfront.originRequestQueryStringBehavior.allowList(jsii.String("username")),
})

cloudfront.NewDistribution(this, jsii.String("myDistCustomPolicy"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: bucketOrigin,
		originRequestPolicy: myOriginRequestPolicy,
	},
})
Customizing Response Headers with Response Headers Policies

You can configure CloudFront to add one or more HTTP headers to the responses that it sends to viewers (web browsers or other clients), without making any changes to the origin or writing any code. To specify the headers that CloudFront adds to HTTP responses, you use a response headers policy. CloudFront adds the headers regardless of whether it serves the object from the cache or has to retrieve the object from the origin. If the origin response includes one or more of the headers that’s in a response headers policy, the policy can specify whether CloudFront uses the header it received from the origin or overwrites it with the one in the policy. See https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/adding-response-headers.html

// Using an existing managed response headers policy
var bucketOrigin s3Origin

cloudfront.NewDistribution(this, jsii.String("myDistManagedPolicy"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: bucketOrigin,
		responseHeadersPolicy: cloudfront.responseHeadersPolicy_CORS_ALLOW_ALL_ORIGINS(),
	},
})

// Creating a custom response headers policy -- all parameters optional
myResponseHeadersPolicy := cloudfront.NewResponseHeadersPolicy(this, jsii.String("ResponseHeadersPolicy"), &responseHeadersPolicyProps{
	responseHeadersPolicyName: jsii.String("MyPolicy"),
	comment: jsii.String("A default policy"),
	corsBehavior: &responseHeadersCorsBehavior{
		accessControlAllowCredentials: jsii.Boolean(false),

})
cloudfront.NewDistribution(this, jsii.String("myDistCustomPolicy"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: bucketOrigin,
		responseHeadersPolicy: myResponseHeadersPolicy,
	},
})
Validating signed URLs or signed cookies with Trusted Key Groups

CloudFront Distribution supports validating signed URLs or signed cookies using key groups. When a cache behavior contains trusted key groups, CloudFront requires signed URLs or signed cookies for all requests that match the cache behavior.

// Validating signed URLs or signed cookies with Trusted Key Groups

// public key in PEM format
var publicKey string

pubKey := cloudfront.NewPublicKey(this, jsii.String("MyPubKey"), &publicKeyProps{
	encodedKey: publicKey,
})

keyGroup := cloudfront.NewKeyGroup(this, jsii.String("MyKeyGroup"), &keyGroupProps{
	items: []iPublicKey{
		pubKey,
	},
})

cloudfront.NewDistribution(this, jsii.String("Dist"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: origins.NewHttpOrigin(jsii.String("www.example.com")),
		trustedKeyGroups: []iKeyGroup{
			keyGroup,
		},
	},
})
Lambda@Edge

Lambda@Edge is an extension of AWS Lambda, a compute service that lets you execute functions that customize the content that CloudFront delivers. You can author Node.js or Python functions in the US East (N. Virginia) region, and then execute them in AWS locations globally that are closer to the viewer, without provisioning or managing servers. Lambda@Edge functions are associated with a specific behavior and event type. Lambda@Edge can be used to rewrite URLs, alter responses based on headers or cookies, or authorize requests based on headers or authorization tokens.

The following shows a Lambda@Edge function added to the default behavior and triggered on every request:

var myBucket bucket
// A Lambda@Edge function added to default behavior of a Distribution
// and triggered on every request
myFunc := #error#.NewEdgeFunction(this, jsii.String("MyFunction"), &edgeFunctionProps{
	runtime: lambda.runtime_NODEJS_12_X(),
	handler: jsii.String("index.handler"),
	code: lambda.code.fromAsset(path.join(__dirname, jsii.String("lambda-handler"))),
})
cloudfront.NewDistribution(this, jsii.String("myDist"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: origins.NewS3Origin(myBucket),
		edgeLambdas: []edgeLambda{
			&edgeLambda{
				functionVersion: myFunc.currentVersion,
				eventType: cloudfront.lambdaEdgeEventType_VIEWER_REQUEST,
			},
		},
	},
})

Note: Lambda@Edge functions must be created in the us-east-1 region, regardless of the region of the CloudFront distribution and stack. To make it easier to request functions for Lambda@Edge, the EdgeFunction construct can be used. The EdgeFunction construct will automatically request a function in us-east-1, regardless of the region of the current stack. EdgeFunction has the same interface as Function and can be created and used interchangeably. Please note that using EdgeFunction requires that the us-east-1 region has been bootstrapped. See https://docs.aws.amazon.com/cdk/latest/guide/bootstrapping.html for more about bootstrapping regions.

If the stack is in us-east-1, a "normal" lambda.Function can be used instead of an EdgeFunction.

// Using a lambda Function instead of an EdgeFunction for stacks in `us-east-`.
myFunc := lambda.NewFunction(this, jsii.String("MyFunction"), &functionProps{
	runtime: lambda.runtime_NODEJS_12_X(),
	handler: jsii.String("index.handler"),
	code: lambda.code.fromAsset(path.join(__dirname, jsii.String("lambda-handler"))),
})

If the stack is not in us-east-1, and you need references from different applications on the same account, you can also set a specific stack ID for each Lambda@Edge.

// Setting stackIds for EdgeFunctions that can be referenced from different applications
// on the same account.
myFunc1 := #error#.NewEdgeFunction(this, jsii.String("MyFunction1"), &edgeFunctionProps{
	runtime: lambda.runtime_NODEJS_12_X(),
	handler: jsii.String("index.handler"),
	code: lambda.code.fromAsset(path.join(__dirname, jsii.String("lambda-handler1"))),
	stackId: jsii.String("edge-lambda-stack-id-1"),
})

myFunc2 := #error#.NewEdgeFunction(this, jsii.String("MyFunction2"), &edgeFunctionProps{
	runtime: lambda.*runtime_NODEJS_12_X(),
	handler: jsii.String("index.handler"),
	code: lambda.*code.fromAsset(path.join(__dirname, jsii.String("lambda-handler2"))),
	stackId: jsii.String("edge-lambda-stack-id-2"),
})

Lambda@Edge functions can also be associated with additional behaviors, either at or after Distribution creation time.

// Associating a Lambda@Edge function with additional behaviors.

var myFunc edgeFunction
// assigning at Distribution creation
var myBucket bucket

myOrigin := origins.NewS3Origin(myBucket)
myDistribution := cloudfront.NewDistribution(this, jsii.String("myDist"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: myOrigin,
	},
	additionalBehaviors: map[string]*behaviorOptions{
		"images/*": &behaviorOptions{
			"origin": myOrigin,
			"edgeLambdas": []EdgeLambda{
				&EdgeLambda{
					"functionVersion": myFunc.currentVersion,
					"eventType": cloudfront.LambdaEdgeEventType_ORIGIN_REQUEST,
					"includeBody": jsii.Boolean(true),
				},
			},
		},
	},
})

// assigning after creation
myDistribution.addBehavior(jsii.String("images/*"), myOrigin, &addBehaviorOptions{
	edgeLambdas: []edgeLambda{
		&edgeLambda{
			functionVersion: myFunc.currentVersion,
			eventType: cloudfront.lambdaEdgeEventType_VIEWER_RESPONSE,
		},
	},
})

Adding an existing Lambda@Edge function created in a different stack to a CloudFront distribution.

// Adding an existing Lambda@Edge function created in a different stack
// to a CloudFront distribution.
var s3Bucket bucket

functionVersion := lambda.version.fromVersionArn(this, jsii.String("Version"), jsii.String("arn:aws:lambda:us-east-1:123456789012:function:functionName:1"))

cloudfront.NewDistribution(this, jsii.String("distro"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: origins.NewS3Origin(s3Bucket),
		edgeLambdas: []edgeLambda{
			&edgeLambda{
				functionVersion: functionVersion,
				eventType: cloudfront.lambdaEdgeEventType_VIEWER_REQUEST,
			},
		},
	},
})
CloudFront Function

You can also deploy CloudFront functions and add them to a CloudFront distribution.

var s3Bucket bucket
// Add a cloudfront Function to a Distribution
cfFunction := cloudfront.NewFunction(this, jsii.String("Function"), &functionProps{
	code: cloudfront.functionCode.fromInline(jsii.String("function handler(event) { return event.request }")),
})
cloudfront.NewDistribution(this, jsii.String("distro"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: origins.NewS3Origin(s3Bucket),
		functionAssociations: []functionAssociation{
			&functionAssociation{
				function: cfFunction,
				eventType: cloudfront.functionEventType_VIEWER_REQUEST,
			},
		},
	},
})

It will auto-generate the name of the function and deploy it to the live stage.

Additionally, you can load the function's code from a file using the FunctionCode.fromFile() method.

Logging

You can configure CloudFront to create log files that contain detailed information about every user request that CloudFront receives. The logs can go to either an existing bucket, or a bucket will be created for you.

// Configure logging for Distributions

// Simplest form - creates a new bucket and logs to it.
// Configure logging for Distributions
// Simplest form - creates a new bucket and logs to it.
cloudfront.NewDistribution(this, jsii.String("myDist"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: origins.NewHttpOrigin(jsii.String("www.example.com")),
	},
	enableLogging: jsii.Boolean(true),
})

// You can optionally log to a specific bucket, configure whether cookies are logged, and give the log files a prefix.
// You can optionally log to a specific bucket, configure whether cookies are logged, and give the log files a prefix.
cloudfront.NewDistribution(this, jsii.String("myDist"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: origins.NewHttpOrigin(jsii.String("www.example.com")),
	},
	enableLogging: jsii.Boolean(true),
	 // Optional, this is implied if logBucket is specified
	logBucket: s3.NewBucket(this, jsii.String("LogBucket")),
	logFilePrefix: jsii.String("distribution-access-logs/"),
	logIncludesCookies: jsii.Boolean(true),
})
Importing Distributions

Existing distributions can be imported as well; note that like most imported constructs, an imported distribution cannot be modified. However, it can be used as a reference for other higher-level constructs.

// Using a reference to an imported Distribution
distribution := cloudfront.distribution.fromDistributionAttributes(this, jsii.String("ImportedDist"), &distributionAttributes{
	domainName: jsii.String("d111111abcdef8.cloudfront.net"),
	distributionId: jsii.String("012345ABCDEF"),
})

Migrating from the original CloudFrontWebDistribution to the newer Distribution construct

It's possible to migrate a distribution from the original to the modern API. The changes necessary are the following:

The Distribution

Replace new CloudFrontWebDistribution with new Distribution. Some configuration properties have been changed:

Old API New API
originConfigs defaultBehavior; use additionalBehaviors if necessary
viewerCertificate certificate; use domainNames for aliases
errorConfigurations errorResponses
loggingConfig enableLogging; configure with logBucket logFilePrefix and logIncludesCookies
viewerProtocolPolicy removed; set on each behavior instead. default changed from REDIRECT_TO_HTTPS to ALLOW_ALL

After switching constructs, you need to maintain the same logical ID for the underlying CfnDistribution if you wish to avoid the deletion and recreation of your distribution. To do this, use escape hatches to override the logical ID created by the new Distribution construct with the logical ID created by the old construct.

Example:

var sourceBucket bucket


myDistribution := cloudfront.NewDistribution(this, jsii.String("MyCfWebDistribution"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: origins.NewS3Origin(sourceBucket),
	},
})
cfnDistribution := myDistribution.node.defaultChild.(cfnDistribution)
cfnDistribution.overrideLogicalId(jsii.String("MyDistributionCFDistribution3H55TI9Q"))
Behaviors

The modern API makes use of the CloudFront Origins module to easily configure your origin. Replace your origin configuration with the relevant CloudFront Origins class. For example, here's a behavior with an S3 origin:

var sourceBucket bucket
var oai originAccessIdentity


cloudfront.NewCloudFrontWebDistribution(this, jsii.String("MyCfWebDistribution"), &cloudFrontWebDistributionProps{
	originConfigs: []sourceConfiguration{
		&sourceConfiguration{
			s3OriginSource: &s3OriginConfig{
				s3BucketSource: sourceBucket,
				originAccessIdentity: oai,
			},
			behaviors: []behavior{
				&behavior{
					isDefaultBehavior: jsii.Boolean(true),
				},
			},
		},
	},
})

Becomes:

var sourceBucket bucket


distribution := cloudfront.NewDistribution(this, jsii.String("MyCfWebDistribution"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: origins.NewS3Origin(sourceBucket),
	},
})

In the original API all behaviors are defined in the originConfigs property. The new API is optimized for a single origin and behavior, so the default behavior and additional behaviors will be defined separately.

var sourceBucket bucket
var oai originAccessIdentity


cloudfront.NewCloudFrontWebDistribution(this, jsii.String("MyCfWebDistribution"), &cloudFrontWebDistributionProps{
	originConfigs: []sourceConfiguration{
		&sourceConfiguration{
			s3OriginSource: &s3OriginConfig{
				s3BucketSource: sourceBucket,
				originAccessIdentity: oai,
			},
			behaviors: []behavior{
				&behavior{
					isDefaultBehavior: jsii.Boolean(true),
				},
			},
		},
		&sourceConfiguration{
			customOriginSource: &customOriginConfig{
				domainName: jsii.String("MYALIAS"),
			},
			behaviors: []*behavior{
				&behavior{
					pathPattern: jsii.String("/somewhere"),
				},
			},
		},
	},
})

Becomes:

var sourceBucket bucket


distribution := cloudfront.NewDistribution(this, jsii.String("MyCfWebDistribution"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: origins.NewS3Origin(sourceBucket),
	},
	additionalBehaviors: map[string]*behaviorOptions{
		"/somewhere": &behaviorOptions{
			"origin": origins.NewHttpOrigin(jsii.String("MYALIAS")),
		},
	},
})
Certificates

If you are using an ACM certificate, you can pass the certificate directly to the certificate prop. Any aliases used before in the ViewerCertificate class should be passed in to the domainNames prop in the modern API.

import acm "github.com/aws/aws-cdk-go/awscdk"
var certificate certificate
var sourceBucket bucket


viewerCertificate := cloudfront.viewerCertificate.fromAcmCertificate(certificate, &viewerCertificateOptions{
	aliases: []*string{
		jsii.String("MYALIAS"),
	},
})

cloudfront.NewCloudFrontWebDistribution(this, jsii.String("MyCfWebDistribution"), &cloudFrontWebDistributionProps{
	originConfigs: []sourceConfiguration{
		&sourceConfiguration{
			s3OriginSource: &s3OriginConfig{
				s3BucketSource: sourceBucket,
			},
			behaviors: []behavior{
				&behavior{
					isDefaultBehavior: jsii.Boolean(true),
				},
			},
		},
	},
	viewerCertificate: viewerCertificate,
})

Becomes:

import acm "github.com/aws/aws-cdk-go/awscdk"
var certificate certificate
var sourceBucket bucket


distribution := cloudfront.NewDistribution(this, jsii.String("MyCfWebDistribution"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: origins.NewS3Origin(sourceBucket),
	},
	domainNames: []*string{
		jsii.String("MYALIAS"),
	},
	certificate: certificate,
})

IAM certificates aren't directly supported by the new API, but can be easily configured through escape hatches

var sourceBucket bucket

viewerCertificate := cloudfront.viewerCertificate.fromIamCertificate(jsii.String("MYIAMROLEIDENTIFIER"), &viewerCertificateOptions{
	aliases: []*string{
		jsii.String("MYALIAS"),
	},
})

cloudfront.NewCloudFrontWebDistribution(this, jsii.String("MyCfWebDistribution"), &cloudFrontWebDistributionProps{
	originConfigs: []sourceConfiguration{
		&sourceConfiguration{
			s3OriginSource: &s3OriginConfig{
				s3BucketSource: sourceBucket,
			},
			behaviors: []behavior{
				&behavior{
					isDefaultBehavior: jsii.Boolean(true),
				},
			},
		},
	},
	viewerCertificate: viewerCertificate,
})

Becomes:

var sourceBucket bucket

distribution := cloudfront.NewDistribution(this, jsii.String("MyCfWebDistribution"), &distributionProps{
	defaultBehavior: &behaviorOptions{
		origin: origins.NewS3Origin(sourceBucket),
	},
	domainNames: []*string{
		jsii.String("MYALIAS"),
	},
})

cfnDistribution := distribution.node.defaultChild.(cfnDistribution)

cfnDistribution.addPropertyOverride(jsii.String("ViewerCertificate.IamCertificateId"), jsii.String("MYIAMROLEIDENTIFIER"))
cfnDistribution.addPropertyOverride(jsii.String("ViewerCertificate.SslSupportMethod"), jsii.String("sni-only"))
Other changes

A number of default settings have changed on the new API when creating a new distribution, behavior, and origin. After making the major changes needed for the migration, run cdk diff to see what settings have changed. If no changes are desired during migration, you will at the least be able to use escape hatches to override what the CDK synthesizes, if you can't change the properties directly.

CloudFrontWebDistribution API

The CloudFrontWebDistribution construct is the original construct written for working with CloudFront distributions. Users are encouraged to use the newer Distribution instead, as it has a simpler interface and receives new features faster.

Example usage:

// Using a CloudFrontWebDistribution construct.

var sourceBucket bucket

distribution := cloudfront.NewCloudFrontWebDistribution(this, jsii.String("MyDistribution"), &cloudFrontWebDistributionProps{
	originConfigs: []sourceConfiguration{
		&sourceConfiguration{
			s3OriginSource: &s3OriginConfig{
				s3BucketSource: sourceBucket,
			},
			behaviors: []behavior{
				&behavior{
					isDefaultBehavior: jsii.Boolean(true),
				},
			},
		},
	},
})
Viewer certificate

By default, CloudFront Web Distributions will answer HTTPS requests with CloudFront's default certificate, only containing the distribution domainName (e.g. d111111abcdef8.cloudfront.net). You can customize the viewer certificate property to provide a custom certificate and/or list of domain name aliases to fit your needs.

See Using Alternate Domain Names and HTTPS in the CloudFront User Guide.

Default certificate

You can customize the default certificate aliases. This is intended to be used in combination with CNAME records in your DNS zone.

Example:

s3BucketSource := s3.NewBucket(this, jsii.String("Bucket"))

distribution := cloudfront.NewCloudFrontWebDistribution(this, jsii.String("AnAmazingWebsiteProbably"), &cloudFrontWebDistributionProps{
	originConfigs: []sourceConfiguration{
		&sourceConfiguration{
			s3OriginSource: &s3OriginConfig{
				s3BucketSource: s3BucketSource,
			},
			behaviors: []behavior{
				&behavior{
					isDefaultBehavior: jsii.Boolean(true),
				},
			},
		},
	},
	viewerCertificate: cloudfront.viewerCertificate.fromCloudFrontDefaultCertificate(jsii.String("www.example.com")),
})
ACM certificate

You can change the default certificate by one stored AWS Certificate Manager, or ACM. Those certificate can either be generated by AWS, or purchased by another CA imported into ACM.

For more information, see the aws-certificatemanager module documentation or Importing Certificates into AWS Certificate Manager in the AWS Certificate Manager User Guide.

Example:

s3BucketSource := s3.NewBucket(this, jsii.String("Bucket"))

certificate := certificatemanager.NewCertificate(this, jsii.String("Certificate"), &certificateProps{
	domainName: jsii.String("example.com"),
	subjectAlternativeNames: []*string{
		jsii.String("*.example.com"),
	},
})

distribution := cloudfront.NewCloudFrontWebDistribution(this, jsii.String("AnAmazingWebsiteProbably"), &cloudFrontWebDistributionProps{
	originConfigs: []sourceConfiguration{
		&sourceConfiguration{
			s3OriginSource: &s3OriginConfig{
				s3BucketSource: s3BucketSource,
			},
			behaviors: []behavior{
				&behavior{
					isDefaultBehavior: jsii.Boolean(true),
				},
			},
		},
	},
	viewerCertificate: cloudfront.viewerCertificate.fromAcmCertificate(certificate, &viewerCertificateOptions{
		aliases: []*string{
			jsii.String("example.com"),
			jsii.String("www.example.com"),
		},
		securityPolicy: cloudfront.securityPolicyProtocol_TLS_V1,
		 // default
		sslMethod: cloudfront.sSLMethod_SNI,
	}),
})
IAM certificate

You can also import a certificate into the IAM certificate store.

See Importing an SSL/TLS Certificate in the CloudFront User Guide.

Example:

s3BucketSource := s3.NewBucket(this, jsii.String("Bucket"))

distribution := cloudfront.NewCloudFrontWebDistribution(this, jsii.String("AnAmazingWebsiteProbably"), &cloudFrontWebDistributionProps{
	originConfigs: []sourceConfiguration{
		&sourceConfiguration{
			s3OriginSource: &s3OriginConfig{
				s3BucketSource: s3BucketSource,
			},
			behaviors: []behavior{
				&behavior{
					isDefaultBehavior: jsii.Boolean(true),
				},
			},
		},
	},
	viewerCertificate: cloudfront.viewerCertificate.fromIamCertificate(jsii.String("certificateId"), &viewerCertificateOptions{
		aliases: []*string{
			jsii.String("example.com"),
		},
		securityPolicy: cloudfront.securityPolicyProtocol_SSL_V3,
		 // default
		sslMethod: cloudfront.sSLMethod_SNI,
	}),
})
Trusted Key Groups

CloudFront Web Distributions supports validating signed URLs or signed cookies using key groups. When a cache behavior contains trusted key groups, CloudFront requires signed URLs or signed cookies for all requests that match the cache behavior.

Example:

// Using trusted key groups for Cloudfront Web Distributions.
var sourceBucket bucket
var publicKey string

pubKey := cloudfront.NewPublicKey(this, jsii.String("MyPubKey"), &publicKeyProps{
	encodedKey: publicKey,
})

keyGroup := cloudfront.NewKeyGroup(this, jsii.String("MyKeyGroup"), &keyGroupProps{
	items: []iPublicKey{
		pubKey,
	},
})

cloudfront.NewCloudFrontWebDistribution(this, jsii.String("AnAmazingWebsiteProbably"), &cloudFrontWebDistributionProps{
	originConfigs: []sourceConfiguration{
		&sourceConfiguration{
			s3OriginSource: &s3OriginConfig{
				s3BucketSource: sourceBucket,
			},
			behaviors: []behavior{
				&behavior{
					isDefaultBehavior: jsii.Boolean(true),
					trustedKeyGroups: []iKeyGroup{
						keyGroup,
					},
				},
			},
		},
	},
})
Restrictions

CloudFront supports adding restrictions to your distribution.

See Restricting the Geographic Distribution of Your Content in the CloudFront User Guide.

Example:

// Adding restrictions to a Cloudfront Web Distribution.
var sourceBucket bucket

cloudfront.NewCloudFrontWebDistribution(this, jsii.String("MyDistribution"), &cloudFrontWebDistributionProps{
	originConfigs: []sourceConfiguration{
		&sourceConfiguration{
			s3OriginSource: &s3OriginConfig{
				s3BucketSource: sourceBucket,
			},
			behaviors: []behavior{
				&behavior{
					isDefaultBehavior: jsii.Boolean(true),
				},
			},
		},
	},
	geoRestriction: cloudfront.geoRestriction.allowlist(jsii.String("US"), jsii.String("GB")),
})
Connection behaviors between CloudFront and your origin

CloudFront provides you even more control over the connection behaviors between CloudFront and your origin. You can now configure the number of connection attempts CloudFront will make to your origin and the origin connection timeout for each attempt.

See Origin Connection Attempts

See Origin Connection Timeout

Example usage:

// Configuring connection behaviors between Cloudfront and your origin
distribution := cloudfront.NewCloudFrontWebDistribution(this, jsii.String("MyDistribution"), &cloudFrontWebDistributionProps{
	originConfigs: []sourceConfiguration{
		&sourceConfiguration{
			connectionAttempts: jsii.Number(3),
			connectionTimeout: awscdk.Duration.seconds(jsii.Number(10)),
			behaviors: []behavior{
				&behavior{
					isDefaultBehavior: jsii.Boolean(true),
				},
			},
		},
	},
})
Origin Fallback

In case the origin source is not available and answers with one of the specified status codes the failover origin source will be used.

// Configuring origin fallback options for the CloudFrontWebDistribution
// Configuring origin fallback options for the CloudFrontWebDistribution
cloudfront.NewCloudFrontWebDistribution(this, jsii.String("ADistribution"), &cloudFrontWebDistributionProps{
	originConfigs: []sourceConfiguration{
		&sourceConfiguration{
			s3OriginSource: &s3OriginConfig{
				s3BucketSource: s3.bucket.fromBucketName(this, jsii.String("aBucket"), jsii.String("myoriginbucket")),
				originPath: jsii.String("/"),
				originHeaders: map[string]*string{
					"myHeader": jsii.String("42"),
				},
				originShieldRegion: jsii.String("us-west-2"),
			},
			failoverS3OriginSource: &s3OriginConfig{
				s3BucketSource: s3.*bucket.fromBucketName(this, jsii.String("aBucketFallback"), jsii.String("myoriginbucketfallback")),
				originPath: jsii.String("/somewhere"),
				originHeaders: map[string]*string{
					"myHeader2": jsii.String("21"),
				},
				originShieldRegion: jsii.String("us-east-1"),
			},
			failoverCriteriaStatusCodes: []failoverStatusCode{
				cloudfront.*failoverStatusCode_INTERNAL_SERVER_ERROR,
			},
			behaviors: []behavior{
				&behavior{
					isDefaultBehavior: jsii.Boolean(true),
				},
			},
		},
	},
})

KeyGroup & PublicKey API

You can create a key group to use with CloudFront signed URLs and signed cookies You can add public keys to use with CloudFront features such as signed URLs, signed cookies, and field-level encryption.

The following example command uses OpenSSL to generate an RSA key pair with a length of 2048 bits and save to the file named private_key.pem.

openssl genrsa -out private_key.pem 2048

The resulting file contains both the public and the private key. The following example command extracts the public key from the file named private_key.pem and stores it in public_key.pem.

openssl rsa -pubout -in private_key.pem -out public_key.pem

Note: Don't forget to copy/paste the contents of public_key.pem file including -----BEGIN PUBLIC KEY----- and -----END PUBLIC KEY----- lines into encodedKey parameter when creating a PublicKey.

Example:

// Create a key group to use with CloudFront signed URLs and signed cookies.
// Create a key group to use with CloudFront signed URLs and signed cookies.
cloudfront.NewKeyGroup(this, jsii.String("MyKeyGroup"), &keyGroupProps{
	items: []iPublicKey{
		cloudfront.NewPublicKey(this, jsii.String("MyPublicKey"), &publicKeyProps{
			encodedKey: jsii.String("..."),
		}),
	},
})

A CloudFormation `AWS::CloudFront::CachePolicy`.

A cache policy.

When it’s attached to a cache behavior, the cache policy determines the following:

- The values that CloudFront includes in the cache key. These values can include HTTP headers, cookies, and URL query strings. CloudFront uses the cache key to find an object in its cache that it can return to the viewer. - The default, minimum, and maximum time to live (TTL) values that you want objects to stay in the CloudFront cache.

The headers, cookies, and query strings that are included in the cache key are automatically included in requests that CloudFront sends to the origin. CloudFront sends a request when it can’t find a valid object in its cache that matches the request’s cache key. If you want to send values to the origin but *not* include them in the cache key, use `OriginRequestPolicy` .

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import "github.com/aws/aws-cdk-go/awscdk"

cfnCachePolicy := awscdk.Aws_cloudfront.NewCfnCachePolicy(this, jsii.String("MyCfnCachePolicy"), &cfnCachePolicyProps{

CloudFront sends a request when it can’t find an object in its cache that matches the request’s cache key. If you want to send values to the origin but *not* include them in the cache key, use `OriginRequestPolicy` .

	// 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).

	// > 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.

}

A complex type that describes how CloudFront processes requests.

You must create at least as many cache behaviors (including the default cache behavior) as you have origins if you want CloudFront to serve objects from all of the origins. Each cache behavior specifies the one origin from which you want CloudFront to get objects. If you have two origins and only the default cache behavior, the default cache behavior will cause CloudFront to get objects from one of the origins, but the other origin is never used.

For the current quota (formerly known as limit) on the number of cache behaviors that you can add to a distribution, see [Quotas](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/cloudfront-limits.html) in the *Amazon CloudFront Developer Guide* .

If you don’t want to specify any cache behaviors, include only an empty `CacheBehaviors` element. Don’t include an empty `CacheBehavior` element because this is invalid.

To delete all cache behaviors in an existing distribution, update the distribution configuration and include only an empty `CacheBehaviors` element.

To add, change, or remove one or more cache behaviors, update the distribution configuration and specify all of the cache behaviors that you want to include in the updated distribution.

For more information about cache behaviors, see [Cache Behavior Settings](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/distribution-web-values-specify.html#DownloadDistValuesCacheBehavior) in the *Amazon CloudFront Developer Guide* .

	// The HTTP status code that you want CloudFront to return to the viewer along with the custom error page.
	//
	// There are a variety of reasons that you might want CloudFront to return a status code different from the status code that 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 intercepted.
	// - 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 `ResponsePagePath` .
	ResponseCode *float64 `field:"optional" json:"responseCode" yaml:"responseCode"`
	// The path to the custom error page that you want CloudFront to return to a viewer when your origin returns the HTTP status code specified by `ErrorCode` , for example, `/4xx-errors/403-forbidden.html` . If you want to store your objects 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 include a cache behavior for which the path pattern routes requests for your custom error pages to that location, for example, `/4xx-errors/*` .
	// - The value of `TargetOriginId` specifies the value of the `ID` element for the origin that contains your custom error pages.
	//
	// If you specify a value for `ResponsePagePath` , you must also specify a value for `ResponseCode` .
	//
	// We recommend that you store custom error pages in an Amazon S3 bucket. If you store custom error pages on an HTTP server and the server starts to return 5xx errors, CloudFront can't get the files that you want to return to viewers because the origin server is unavailable.
	ResponsePagePath *string `field:"optional" json:"responsePagePath" yaml:"responsePagePath"`

A complex type that controls:.

- Whether CloudFront replaces HTTP status codes in the 4xx and 5xx range with custom error messages before returning the response to the viewer. - How long CloudFront caches HTTP status codes in the 4xx and 5xx range.

A custom origin.

A custom origin is any origin that is *not* an Amazon S3 bucket, with one exception. An Amazon S3 bucket that is [configured with static website hosting](https://docs.aws.amazon.com/AmazonS3/latest/dev/WebsiteHosting.html) *is* a custom origin.

An origin group includes two origins (a primary origin and a second origin to failover to) and a failover criteria that you specify.

You create an origin group to support origin failover in CloudFront. When you create or update a distribution, you can specifiy the origin group instead of a single origin, and CloudFront will failover from the primary origin to the second origin under the failover conditions that you've chosen.

An origin.

An origin is the location where content is stored, and from which CloudFront gets content to serve to viewers. To specify an origin:

- Use `S3OriginConfig` to specify an Amazon S3 bucket that is not configured with static website hosting. - Use `CustomOriginConfig` to specify all other kinds of origins, including:

- An Amazon S3 bucket that is configured with static website hosting - An Elastic Load Balancing load balancer - An AWS Elemental MediaPackage endpoint - An AWS Elemental MediaStore container - Any other HTTP server, running on an Amazon EC2 instance or any other kind of host

For the current maximum number of origins that you can specify per distribution, see [General Quotas on Web Distributions](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/cloudfront-limits.html#limits-web-distributions) in the *Amazon CloudFront Developer Guide* (quotas were formerly referred to as limits).

	SslSupportMethod *string `field:"optional" json:"sslSupportMethod" yaml:"sslSupportMethod"`
}

A complex type that determines the distribution’s SSL/TLS configuration for communicating with viewers.

If the distribution doesn’t use `Aliases` (also known as alternate domain names or CNAMEs)—that is, if the distribution uses the CloudFront domain name such as `d111111abcdef8.cloudfront.net` —set `CloudFrontDefaultCertificate` to `true` and leave all other fields empty.

If the distribution uses `Aliases` (alternate domain names or CNAMEs), use the fields in this type to specify the following settings:

- Which viewers the distribution accepts HTTPS connections from: only viewers that support [server name indication (SNI)](https://docs.aws.amazon.com/https://en.wikipedia.org/wiki/Server_Name_Indication) (recommended), or all viewers including those that don’t support SNI.

- To accept HTTPS connections from only viewers that support SNI, set `SSLSupportMethod` to `sni-only` . This is recommended. Most browsers and clients support SNI. (In CloudFormation, the field name is `SslSupportMethod` . Note the different capitalization.) - To accept HTTPS connections from all viewers, including those that don’t support SNI, set `SSLSupportMethod` to `vip` . This is not recommended, and results in additional monthly charges from CloudFront. (In CloudFormation, the field name is `SslSupportMethod` . Note the different capitalization.) - The minimum SSL/TLS protocol version that the distribution can use to communicate with viewers. To specify a minimum version, choose a value for `MinimumProtocolVersion` . For more information, see [Security Policy](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/distribution-web-values-specify.html#DownloadDistValues-security-policy) in the *Amazon CloudFront Developer Guide* . - The location of the SSL/TLS certificate, [AWS Certificate Manager (ACM)](https://docs.aws.amazon.com/acm/latest/userguide/acm-overview.html) (recommended) or [AWS Identity and Access Management (IAM)](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_server-certs.html) . You specify the location by setting a value in one of the following fields (not both):

- `ACMCertificateArn` (In CloudFormation, this field name is `AcmCertificateArn` . Note the different capitalization.) - `IAMCertificateId` (In CloudFormation, this field name is `IamCertificateId` . Note the different capitalization.)

All distributions support HTTPS connections from viewers. To require viewers to use HTTPS only, or to redirect them from HTTP to HTTPS, use `ViewerProtocolPolicy` in the `CacheBehavior` or `DefaultCacheBehavior` . To specify how CloudFront should use SSL/TLS to communicate with your custom origin, use `CustomOriginConfig` .

For more information, see [Using HTTPS with CloudFront](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/using-https.html) and [Using Alternate Domain Names and HTTPS](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/using-https-alternate-domain-names.html) in the *Amazon CloudFront Developer Guide* .

A CloudFormation `AWS::CloudFront::Function`.

Creates a CloudFront function.

To create a function, you provide the function code and some configuration information about the function. The response contains an Amazon Resource Name (ARN) that uniquely identifies the function, and the function’s stage.

By default, when you create a function, it’s in the `DEVELOPMENT` stage. In this stage, you can [test the function](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/test-function.html) in the CloudFront console (or with `TestFunction` in the CloudFront API).

When you’re ready to use your function with a CloudFront distribution, publish the function to the `LIVE` stage. You can do this in the CloudFront console, with `PublishFunction` in the CloudFront API, or by updating the `AWS::CloudFront::Function` resource with the `AutoPublish` property set to `true` . When the function is published to the `LIVE` stage, you can attach it to a distribution’s cache behavior, using the function’s ARN.

To automatically publish the function to the `LIVE` stage when it’s created, set the `AutoPublish` property to `true` .

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import "github.com/aws/aws-cdk-go/awscdk"

cfnFunction := awscdk.Aws_cloudfront.NewCfnFunction(this, jsii.String("MyCfnFunction"), &cfnFunctionProps{

A CloudFormation `AWS::CloudFront::OriginRequestPolicy`.

An origin request policy.

When it’s attached to a cache behavior, the origin request policy determines the values that CloudFront includes in requests that it sends to the origin. Each request that CloudFront sends to the origin includes the following:

- The request body and the URL path (without the domain name) from the viewer request. - The headers that CloudFront automatically includes in every origin request, including `Host` , `User-Agent` , and `X-Amz-Cf-Id` . - All HTTP headers, cookies, and URL query strings that are specified in the cache policy or the origin request policy. These can include items from the viewer request and, in the case of headers, additional ones that are added by CloudFront.

CloudFront sends a request when it can’t find an object in its cache that matches the request. If you want to send values to the origin and also include them in the cache key, use `CachePolicy` .

Example: 

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import "github.com/aws/aws-cdk-go/awscdk"

cfnOriginRequestPolicy := awscdk.Aws_cloudfront.NewCfnOriginRequestPolicy(this, jsii.String("MyCfnOriginRequestPolicy"), &cfnOriginRequestPolicyProps{

A CloudFormation `AWS::CloudFront::ResponseHeadersPolicy`.

A response headers policy.

A response headers policy contains information about a set of HTTP response headers and their values.

After you create a response headers policy, you can use its ID to attach it to one or more cache behaviors in a CloudFront distribution. When it’s attached to a cache behavior, CloudFront adds the headers in the policy to HTTP responses that it sends for requests that match the cache behavior.

For more information, see [Adding HTTP headers to CloudFront responses](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/adding-response-headers.html) in the *Amazon CloudFront Developer Guide* .

Amazon CloudFront is a global content delivery network (CDN) service that securely delivers data, videos, applications, and APIs to your viewers with low latency and high transfer speeds.

CloudFront fronts user provided content and caches it at edge locations across the world.

Here's how you can use this construct:

```ts const sourceBucket = new s3.Bucket(this, 'Bucket'); 

const distribution = new cloudfront.CloudFrontWebDistribution(this, 'MyDistribution', {
   originConfigs: [
     {
       s3OriginSource: {
       s3BucketSource: sourceBucket,
       },
       behaviors : [ {isDefaultBehavior: true}],
     },
   ],
});

```

This will create a CloudFront distribution that uses your S3Bucket as it's origin.

You can customize the distribution using additional properties from the CloudFrontWebDistributionProps interface.

Example: 

var sourceBucket bucket

viewerCertificate := cloudfront.viewerCertificate.fromIamCertificate(jsii.String("MYIAMROLEIDENTIFIER"), &viewerCertificateOptions{
	aliases: []*string{
		jsii.String("MYALIAS"),
	},
})

cloudfront.NewCloudFrontWebDistribution(this, jsii.String("MyCfWebDistribution"), &cloudFrontWebDistributionProps{
	originConfigs: []sourceConfiguration{
		&sourceConfiguration{
			s3OriginSource: &s3OriginConfig{
				s3BucketSource: sourceBucket,

			behaviors: []behavior{

type SSLMethod 

type SSLMethod string

The SSL method CloudFront will use for your distribution.

Server Name Indication (SNI) - is an extension to the TLS computer networking protocol by which a client indicates 

which hostname it is attempting to connect to at the start of the handshaking process. This allows a server to present
multiple certificates on the same IP address and TCP port number and hence allows multiple secure (HTTPS) websites

(or any other service over TLS) to be served by the same IP address without requiring all those sites to use the same certificate.

CloudFront can use SNI to host multiple distributions on the same IP - which a large majority of clients will support.

If your clients cannot support SNI however - CloudFront can use dedicated IPs for your distribution - but there is a prorated monthly charge for using this feature. By default, we use SNI - but you can optionally enable dedicated IPs (VIP).

See the CloudFront SSL for more details about pricing : https://aws.amazon.com/cloudfront/custom-ssl-domains/

Example: 

s3BucketSource := s3.NewBucket(this, jsii.String("Bucket"))

distribution := cloudfront.NewCloudFrontWebDistribution(this, jsii.String("AnAmazingWebsiteProbably"), &cloudFrontWebDistributionProps{
	originConfigs: []sourceConfiguration{

A source configuration is a wrapper for CloudFront origins and behaviors.

An origin is what CloudFront will "be in front of" - that is, CloudFront will pull it's assets from an origin.

If you're using s3 as a source - pass the `s3Origin` property, otherwise, pass the `customOriginSource` property.

One or the other must be passed, and it is invalid to pass both in the same SourceConfiguration.
