(unknown)

Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

This is the Amazon CloudFront API Reference. This guide is for developers who need detailed information about the CloudFront API actions, data types, and errors. For detailed information about CloudFront features and their associated API calls, see the Amazon CloudFront Developer Guide.

Sending a Request Using CloudFront

var cloudfront = new AWS.CloudFront();
cloudfront.createCloudFrontOriginAccessIdentity(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the CloudFront object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var cloudfront = new AWS.CloudFront({apiVersion: '2016-11-25'});

You can also set the API version globally in AWS.config.apiVersions using the cloudfront service identifier:

AWS.config.apiVersions = {
  cloudfront: '2016-11-25',
  // other service API versions
};

var cloudfront = new AWS.CloudFront();

Version:

  • 2016-11-25

Waiter Resource States

This service supports a list of resource states that can be polled using the waitFor() method. The resource states are:

distributionDeployed, invalidationCompleted, streamingDistributionDeployed

Constructor Details

new AWS.CloudFront(options = {}) ⇒ Object

Constructs a service object. This object has one method for each API operation.

Examples:

Constructing a CloudFront object

var cloudfront = new AWS.CloudFront({apiVersion: '2016-11-25'});

Options Hash (options):

  • params (map) —

    An optional map of parameters to bind to every request sent by this service object. For more information on bound parameters, see "Working with Services" in the Getting Started Guide.

  • endpoint (String|AWS.Endpoint) —

    The endpoint URI to send requests to. The default endpoint is built from the configured region. The endpoint should be a string like 'https://{service}.{region}.amazonaws.com' or an Endpoint object.

  • accessKeyId (String) —

    your AWS access key ID.

  • secretAccessKey (String) —

    your AWS secret access key.

  • sessionToken (AWS.Credentials) —

    the optional AWS session token to sign requests with.

  • credentials (AWS.Credentials) —

    the AWS credentials to sign requests with. You can either specify this object, or specify the accessKeyId and secretAccessKey options directly.

  • credentialProvider (AWS.CredentialProviderChain) —

    the provider chain used to resolve credentials if no static credentials property is set.

  • region (String) —

    the region to send service requests to. See AWS.CloudFront_20161125.region for more information.

  • maxRetries (Integer) —

    the maximum amount of retries to attempt with a request. See AWS.CloudFront_20161125.maxRetries for more information.

  • maxRedirects (Integer) —

    the maximum amount of redirects to follow with a request. See AWS.CloudFront_20161125.maxRedirects for more information.

  • sslEnabled (Boolean) —

    whether to enable SSL for requests.

  • paramValidation (Boolean|map) —

    whether input parameters should be validated against the operation description before sending the request. Defaults to true. Pass a map to enable any of the following specific validation features:

    • min [Boolean] — Validates that a value meets the min constraint. This is enabled by default when paramValidation is set to true.
    • max [Boolean] — Validates that a value meets the max constraint.
    • pattern [Boolean] — Validates that a string value matches a regular expression.
    • enum [Boolean] — Validates that a string value matches one of the allowable enum values.
  • computeChecksums (Boolean) —

    whether to compute checksums for payload bodies when the service accepts it (currently supported in S3 only)

  • convertResponseTypes (Boolean) —

    whether types are converted when parsing response data. Currently only supported for JSON based services. Turning this off may improve performance on large response payloads. Defaults to true.

  • correctClockSkew (Boolean) —

    whether to apply a clock skew correction and retry requests that fail because of an skewed client clock. Defaults to false.

  • s3ForcePathStyle (Boolean) —

    whether to force path style URLs for S3 objects.

  • s3BucketEndpoint (Boolean) —

    whether the provided endpoint addresses an individual bucket (false if it addresses the root API endpoint). Note that setting this configuration option requires an endpoint to be provided explicitly to the service constructor.

  • s3DisableBodySigning (Boolean) —

    whether S3 body signing should be disabled when using signature version v4. Body signing can only be disabled when using https. Defaults to true.

  • s3UsEast1RegionalEndpoint ('legacy'|'regional') —

    when region is set to 'us-east-1', whether to send s3 request to global endpoints or 'us-east-1' regional endpoints. This config is only applicable to S3 client. Defaults to legacy

  • s3UseArnRegion (Boolean) —

    whether to override the request region with the region inferred from requested resource's ARN. Only available for S3 buckets Defaults to true

  • retryDelayOptions (map) —

    A set of options to configure the retry delay on retryable errors. Currently supported options are:

    • base [Integer] — The base number of milliseconds to use in the exponential backoff for operation retries. Defaults to 100 ms for all services except DynamoDB, where it defaults to 50ms.
    • customBackoff [function] — A custom function that accepts a retry count and error and returns the amount of time to delay in milliseconds. If the result is a non-zero negative value, no further retry attempts will be made. The base option will be ignored if this option is supplied. The function is only called for retryable errors.
  • httpOptions (map) —

    A set of options to pass to the low-level HTTP request. Currently supported options are:

    • proxy [String] — the URL to proxy requests through
    • agent [http.Agent, https.Agent] — the Agent object to perform HTTP requests with. Used for connection pooling. Defaults to the global agent (http.globalAgent) for non-SSL connections. Note that for SSL connections, a special Agent object is used in order to enable peer certificate verification. This feature is only available in the Node.js environment.
    • connectTimeout [Integer] — Sets the socket to timeout after failing to establish a connection with the server after connectTimeout milliseconds. This timeout has no effect once a socket connection has been established.
    • timeout [Integer] — Sets the socket to timeout after timeout milliseconds of inactivity on the socket. Defaults to two minutes (120000).
    • xhrAsync [Boolean] — Whether the SDK will send asynchronous HTTP requests. Used in the browser environment only. Set to false to send requests synchronously. Defaults to true (async on).
    • xhrWithCredentials [Boolean] — Sets the "withCredentials" property of an XMLHttpRequest object. Used in the browser environment only. Defaults to false.
  • apiVersion (String, Date) —

    a String in YYYY-MM-DD format (or a date) that represents the latest possible API version that can be used in all services (unless overridden by apiVersions). Specify 'latest' to use the latest possible version.

  • apiVersions (map<String, String|Date>) —

    a map of service identifiers (the lowercase service class name) with the API version to use when instantiating a service. Specify 'latest' for each individual that can use the latest available version.

  • logger (#write, #log) —

    an object that responds to .write() (like a stream) or .log() (like the console object) in order to log information about requests

  • systemClockOffset (Number) —

    an offset value in milliseconds to apply to all signing times. Use this to compensate for clock skew when your system may be out of sync with the service time. Note that this configuration option can only be applied to the global AWS.config object and cannot be overridden in service-specific configuration. Defaults to 0 milliseconds.

  • signatureVersion (String) —

    the signature version to sign requests with (overriding the API configuration). Possible values are: 'v2', 'v3', 'v4'.

  • signatureCache (Boolean) —

    whether the signature to sign requests with (overriding the API configuration) is cached. Only applies to the signature version 'v4'. Defaults to true.

  • dynamoDbCrc32 (Boolean) —

    whether to validate the CRC32 checksum of HTTP response bodies returned by DynamoDB. Default: true.

  • useAccelerateEndpoint (Boolean) —

    Whether to use the S3 Transfer Acceleration endpoint with the S3 service. Default: false.

Method Details

createCloudFrontOriginAccessIdentity(params = {}, callback) ⇒ AWS.Request

Creates a new origin access identity. If you're using Amazon S3 for your origin, you can use an origin access identity to require users to access your content using a CloudFront URL instead of the Amazon S3 URL. For more information about how to use origin access identities, see Serving Private Content through CloudFront in the Amazon CloudFront Developer Guide.

Service Reference:

Examples:

Calling the createCloudFrontOriginAccessIdentity operation

var params = {
  CloudFrontOriginAccessIdentityConfig: { /* required */
    CallerReference: 'STRING_VALUE', /* required */
    Comment: 'STRING_VALUE' /* required */
  }
};
cloudfront.createCloudFrontOriginAccessIdentity(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • CloudFrontOriginAccessIdentityConfig — (map)

      The current configuration information for the identity.

      • CallerReference — required — (String)

        A unique number that ensures the request can't be replayed.

        If the CallerReference is new (no matter the content of the CloudFrontOriginAccessIdentityConfig object), a new origin access identity is created.

        If the CallerReference is a value already sent in a previous identity request, and the content of the CloudFrontOriginAccessIdentityConfig is identical to the original request (ignoring white space), the response includes the same information returned to the original request.

        If the CallerReference is a value you already sent in a previous request to create an identity, but the content of the CloudFrontOriginAccessIdentityConfig is different from the original request, CloudFront returns a CloudFrontOriginAccessIdentityAlreadyExists error.

      • Comment — required — (String)

        Any comments you want to include about the origin access identity.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • CloudFrontOriginAccessIdentity — (map)

        The origin access identity's information.

        • Id — required — (String)

          The ID for the origin access identity. For example: E74FTE3AJFJ256A.

        • S3CanonicalUserId — required — (String)

          The Amazon S3 canonical user ID for the origin access identity, used when giving the origin access identity read permission to an object in Amazon S3.

        • CloudFrontOriginAccessIdentityConfig — (map)

          The current configuration information for the identity.

          • CallerReference — required — (String)

            A unique number that ensures the request can't be replayed.

            If the CallerReference is new (no matter the content of the CloudFrontOriginAccessIdentityConfig object), a new origin access identity is created.

            If the CallerReference is a value already sent in a previous identity request, and the content of the CloudFrontOriginAccessIdentityConfig is identical to the original request (ignoring white space), the response includes the same information returned to the original request.

            If the CallerReference is a value you already sent in a previous request to create an identity, but the content of the CloudFrontOriginAccessIdentityConfig is different from the original request, CloudFront returns a CloudFrontOriginAccessIdentityAlreadyExists error.

          • Comment — required — (String)

            Any comments you want to include about the origin access identity.

      • Location — (String)

        The fully qualified URI of the new origin access identity just created. For example: https://cloudfront.amazonaws.com/2010-11-01/origin-access-identity/cloudfront/E74FTE3AJFJ256A.

      • ETag — (String)

        The current version of the origin access identity created.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

});

Parameters:

  • params (Object) (defaults to: {}) —
    • DistributionConfig — (map)

      The distribution's configuration information.

      • CallerReference — required — (String)

        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 you already sent in a previous request to create a distribution, and if the content of the DistributionConfig is identical to the original request (ignoring white space), CloudFront returns the same the response that it returned to the original request.

        If CallerReference is a value you already sent in a previous request to create a distribution but the content of the DistributionConfig is different from the original request, CloudFront returns a DistributionAlreadyExists error.

      • Aliases — (map)

        A complex type that contains information about CNAMEs (alternate domain names), if any, for this distribution.

        • Quantity — required — (Integer)

          The number of CNAME aliases, if any, that you want to associate with this distribution.

        • Items — (Array<String>)

          A complex type that contains the CNAME aliases, if any, that you want to associate with this distribution.

      • DefaultRootObject — (String)

        The object that you want CloudFront to request from your origin (for example, index.html) when a viewer requests the root URL for your distribution (http://www.example.com) instead of an object in your distribution (http://www.example.com/product-description.html). Specifying a default root object avoids exposing the contents of your distribution.

        Specify only the object name, for example, index.html. Do not add a / before the object name.

        If you don't want to specify a default root object when you create a distribution, include an empty DefaultRootObject element.

        To delete the default root object from an existing distribution, update the distribution configuration and include an empty DefaultRootObject element.

        To replace the default root object, update the distribution configuration and specify the new object.

        For more information about the default root object, see Creating a Default Root Object in the Amazon CloudFront Developer Guide.

      • Origins — required — (map)

        A complex type that contains information about origins for this distribution.

        • Quantity — required — (Integer)

          The number of origins for this distribution.

        • Items — (Array<map>)

          A complex type that contains origins for this distribution.

          • Id — required — (String)

            A unique identifier for the origin. The value of Id must be unique within the distribution.

            When you specify the value of TargetOriginId for the default cache behavior or for another cache behavior, you indicate the origin to which you want the cache behavior to route requests by specifying the value of the Id element for that origin. When a request matches the path pattern for that cache behavior, CloudFront routes the request to the specified origin. For more information, see Cache Behavior Settings in the Amazon CloudFront Developer Guide.

          • DomainName — required — (String)

            Amazon S3 origins: The DNS name of the Amazon S3 bucket from which you want CloudFront to get objects for this origin, for example, myawsbucket.s3.amazonaws.com.

            Constraints for Amazon S3 origins:

            • If you configured Amazon S3 Transfer Acceleration for your bucket, do not specify the s3-accelerate endpoint for DomainName.

            • The bucket name must be between 3 and 63 characters long (inclusive).

            • The bucket name must contain only lowercase characters, numbers, periods, underscores, and dashes.

            • The bucket name must not contain adjacent periods.

            Custom Origins: The DNS domain name for the HTTP server from which you want CloudFront to get objects for this origin, for example, www.example.com.

            Constraints for custom origins:

            • DomainName must be a valid DNS name that contains only a-z, A-Z, 0-9, dot (.), hyphen (-), or underscore (_) characters.

            • The name cannot exceed 128 characters.

          • OriginPath — (String)

            An optional element that causes CloudFront to request your content from a directory in your Amazon S3 bucket or your custom origin. When you include the OriginPath element, specify the directory name, beginning with a /. CloudFront appends the directory name to the value of DomainName, for example, example.com/production. Do not include a / at the end of the directory name.

            For example, suppose you've specified the following values for your distribution:

            • DomainName: An Amazon S3 bucket named myawsbucket.

            • OriginPath: /production

            • CNAME: example.com

            When a user enters example.com/index.html in a browser, CloudFront sends a request to Amazon S3 for myawsbucket/production/index.html.

            When a user enters example.com/acme/index.html in a browser, CloudFront sends a request to Amazon S3 for myawsbucket/production/acme/index.html.

          • CustomHeaders — (map)

            A complex type that contains names and values for the custom headers that you want.

            • Quantity — required — (Integer)

              The number of custom headers, if any, for this distribution.

            • Items — (Array<map>)

              Optional: A list that contains one OriginCustomHeader element for each custom header that you want CloudFront to forward to the origin. If Quantity is 0, omit Items.

              • HeaderName — required — (String)

                The name of a header that you want CloudFront to forward to your origin. For more information, see Forwarding Custom Headers to Your Origin (Web Distributions Only) in the Amazon Amazon CloudFront Developer Guide.

              • HeaderValue — required — (String)

                The value for the header that you specified in the HeaderName field.

          • S3OriginConfig — (map)

            A complex type that contains information about the Amazon S3 origin. If the origin is a custom origin, use the CustomOriginConfig element instead.

            • OriginAccessIdentity — required — (String)

              The CloudFront origin access identity to associate with the origin. Use an origin access identity to configure the origin so that viewers can only access objects in an Amazon S3 bucket through CloudFront. The format of the value is:

              origin-access-identity/CloudFront/ID-of-origin-access-identity

              where ID-of-origin-access-identity is the value that CloudFront returned in the ID element when you created the origin access identity.

              If you want viewers to be able to access objects using either the CloudFront URL or the Amazon S3 URL, specify an empty OriginAccessIdentity element.

              To delete the origin access identity from an existing distribution, update the distribution configuration and include an empty OriginAccessIdentity element.

              To replace the origin access identity, update the distribution configuration and specify the new origin access identity.

              For more information about the origin access identity, see Serving Private Content through CloudFront in the Amazon CloudFront Developer Guide.

          • CustomOriginConfig — (map)

            A complex type that contains information about a custom origin. If the origin is an Amazon S3 bucket, use the S3OriginConfig element instead.

            • HTTPPort — required — (Integer)

              The HTTP port the custom origin listens on.

            • HTTPSPort — required — (Integer)

              The HTTPS port the custom origin listens on.

            • OriginProtocolPolicy — required — (String)

              The origin protocol policy to apply to your origin.

              Possible values include:
              • "http-only"
              • "match-viewer"
              • "https-only"
            • OriginSslProtocols — (map)

              The SSL/TLS protocols that you want CloudFront to use when communicating with your origin over HTTPS.

              • Quantity — required — (Integer)

                The number of SSL/TLS protocols that you want to allow CloudFront to use when establishing an HTTPS connection with this origin.

              • Items — required — (Array<String>)

                A list that contains allowed SSL/TLS protocols for this distribution.

      • DefaultCacheBehavior — required — (map)

        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.

        • TargetOriginId — required — (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.

        • ForwardedValues — required — (map)

          A complex type that specifies how CloudFront handles query strings and cookies.

          • QueryString — required — (Boolean)

            Indicates whether you want CloudFront to forward query strings to the origin that is associated with this cache behavior and cache based on the query string parameters. CloudFront behavior depends on the value of QueryString and on the values that you specify for QueryStringCacheKeys, if any:

            If you specify true for QueryString and you don't specify any values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin and caches based on all query string parameters. Depending on how many query string parameters and values you have, this can adversely affect performance because CloudFront must forward more requests to the origin.

            If you specify true for QueryString and you specify one or more values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin, but it only caches based on the query string parameters that you specify.

            If you specify false for QueryString, CloudFront doesn't forward any query string parameters to the origin, and doesn't cache based on query string parameters.

            For more information, see Configuring CloudFront to Cache Based on Query String Parameters in the Amazon CloudFront Developer Guide.

          • Cookies — required — (map)

            A complex type that specifies whether you want CloudFront to forward cookies to the origin and, if so, which ones. For more information about forwarding cookies to the origin, see How CloudFront Forwards, Caches, and Logs Cookies in the Amazon CloudFront Developer Guide.

            • Forward — required — (String)

              Specifies which cookies to forward to the origin for this cache behavior: all, none, or the list of cookies specified in the WhitelistedNames complex type.

              Amazon S3 doesn't process cookies. When the cache behavior is forwarding requests to an Amazon S3 origin, specify none for the Forward element.

              Possible values include:
              • "none"
              • "whitelist"
              • "all"
            • WhitelistedNames — (map)

              Required if you specify whitelist for the value of Forward:. A complex type that specifies how many different cookies you want CloudFront to forward to the origin for this cache behavior and, if you want to forward selected cookies, the names of those cookies.

              If you specify all or none for the value of Forward, omit WhitelistedNames. If you change the value of Forward from whitelist to all or none and you don't delete the WhitelistedNames element and its child elements, CloudFront deletes them automatically.

              For the current limit on the number of cookie names that you can whitelist for each cache behavior, see Amazon CloudFront Limits in the AWS General Reference.

              • Quantity — required — (Integer)

                The number of different cookies that you want CloudFront to forward to the origin for this cache behavior.

              • Items — (Array<String>)

                A complex type that contains one Name element for each cookie that you want CloudFront to forward to the origin for this cache behavior.

          • Headers — (map)

            A complex type that specifies the Headers, if any, that you want CloudFront to vary upon for this cache behavior.

            • Quantity — required — (Integer)

              The number of different headers that you want CloudFront to forward to the origin for this cache behavior. You can configure each cache behavior in a web distribution to do one of the following:

              • Forward all headers to your origin: Specify 1 for Quantity and * for Name.

                If you configure CloudFront to forward all headers to your origin, CloudFront doesn't cache the objects associated with this cache behavior. Instead, it sends every request to the origin.

              • Forward a whitelist of headers you specify: Specify the number of headers that you want to forward, and specify the header names in Name elements. CloudFront caches your objects based on the values in all of the specified headers. CloudFront also forwards the headers that it forwards by default, but it caches your objects based only on the headers that you specify.

              • Forward only the default headers: Specify 0 for Quantity and omit Items. In this configuration, CloudFront doesn't cache based on the values in the request headers.

            • Items — (Array<String>)

              A complex type that contains one Name element for each header that you want CloudFront to forward to the origin and to vary on for this cache behavior. If Quantity is 0, omit Items.

          • QueryStringCacheKeys — (map)

            A complex type that contains information about the query string parameters that you want CloudFront to use for caching for this cache behavior.

            • Quantity — required — (Integer)

              The number of whitelisted query string parameters for this cache behavior.

            • Items — (Array<String>)

              (Optional) A list that contains the query string parameters that you want CloudFront to use as a basis for caching for this cache behavior. If Quantity is 0, you can omit Items.

        • TrustedSigners — required — (map)

          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.

          • Enabled — required — (Boolean)

            Specifies whether you want to require viewers to use signed URLs to access the files specified by PathPattern and TargetOriginId.

          • Quantity — required — (Integer)

            The number of trusted signers for this cache behavior.

          • Items — (Array<String>)

            Optional: A complex type that contains trusted signers for this cache behavior. If Quantity is 0, you can omit Items.

        • ViewerProtocolPolicy — required — (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: 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.
          Possible values include:
          • "allow-all"
          • "https-only"
          • "redirect-to-https"
        • MinTTL — required — (Integer)

          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).

        • AllowedMethods — (map)

          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.

          • Quantity — required — (Integer)

            The number of HTTP methods that you want CloudFront to forward to your origin. Valid values are 2 (for GET and HEAD requests), 3 (for GET, HEAD, and OPTIONS requests) and 7 (for GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests).

          • Items — required — (Array<String>)

            A complex type that contains the HTTP methods that you want CloudFront to process and forward to your origin.

          • CachedMethods — (map)

            A complex type that controls whether CloudFront caches the response to requests using the specified HTTP methods. There are two choices:

            • CloudFront caches responses to GET and HEAD requests.

            • CloudFront caches responses to GET, HEAD, and OPTIONS requests.

            If you pick the second choice for your Amazon S3 Origin, you may need to forward Access-Control-Request-Method, Access-Control-Request-Headers, and Origin headers for the responses to be cached correctly.

            • Quantity — required — (Integer)

              The number of HTTP methods for which you want CloudFront to cache responses. Valid values are 2 (for caching responses to GET and HEAD requests) and 3 (for caching responses to GET, HEAD, and OPTIONS requests).

            • Items — required — (Array<String>)

              A complex type that contains the HTTP methods that you want CloudFront to cache responses to.

        • SmoothStreaming — (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.

        • DefaultTTL — (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. For more information, see Specifying How Long Objects and Errors Stay in a CloudFront Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.

        • MaxTTL — (Integer)
        • Compress — (Boolean)

          Whether you want CloudFront to automatically compress certain files for this cache behavior. If so, specify true; if not, specify false. For more information, see Serving Compressed Files in the Amazon CloudFront Developer Guide.

        • LambdaFunctionAssociations — (map)

          A complex type that contains zero or more Lambda function associations for a cache behavior.

          • Quantity — required — (Integer)

            The number of Lambda function associations for this cache behavior.

          • Items — (Array<map>)

            Optional: A complex type that contains LambdaFunctionAssociation items for this cache behavior. If Quantity is 0, you can omit Items.

            • LambdaFunctionARN — (String)

              The ARN of the Lambda function.

            • EventType — (String)

              Specifies the event type that triggers a Lambda function invocation. Valid values are:

              • origin-request

              • viewer-response

              • origin-response

              Possible values include:
              • "viewer-request"
              • "viewer-response"

        A complex type that contains zero or more CacheBehavior elements.

        • Quantity — required — (Integer)

          The number of cache behaviors for this distribution.

        • Items — (Array<map>)

          Optional: A complex type that contains cache behaviors for this distribution. If Quantity is 0, you can omit Items.

          • PathPattern — required — (String)

            The pattern (for example, images/*.jpg) that specifies which requests to apply the behavior to. When CloudFront receives a viewer request, the requested path is compared with path patterns in the order in which cache behaviors are listed in the distribution.

            Note: You can optionally include a slash (/) at the beginning of the path pattern. For example, /images/*.jpg. CloudFront behavior is the same with or without the leading /.

            The path pattern for the default cache behavior is * and cannot be changed. If the request for an object does not match the path pattern for any cache behaviors, CloudFront applies the behavior in the default cache behavior.

            For more information, see Path Pattern in the Amazon CloudFront Developer Guide.

          • TargetOriginId — required — (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.

          • ForwardedValues — required — (map)

            A complex type that specifies how CloudFront handles query strings and cookies.

            • QueryString — required — (Boolean)

              Indicates whether you want CloudFront to forward query strings to the origin that is associated with this cache behavior and cache based on the query string parameters. CloudFront behavior depends on the value of QueryString and on the values that you specify for QueryStringCacheKeys, if any:

              If you specify true for QueryString and you don't specify any values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin and caches based on all query string parameters. Depending on how many query string parameters and values you have, this can adversely affect performance because CloudFront must forward more requests to the origin.

              If you specify true for QueryString and you specify one or more values for QueryStringCacheKeys, CloudFront forwards all query string parameters to the origin, but it only caches based on the query string parameters that you specify.

              If you specify false for QueryString, CloudFront doesn't forward any query string parameters to the origin, and doesn't cache based on query string parameters.

              For more information, see Configuring CloudFront to Cache Based on Query String Parameters in the Amazon CloudFront Developer Guide.

            • Cookies — required — (map)

              A complex type that specifies whether you want CloudFront to forward cookies to the origin and, if so, which ones. For more information about forwarding cookies to the origin, see How CloudFront Forwards, Caches, and Logs Cookies in the Amazon CloudFront Developer Guide.

              • Forward — required — (String)

                Specifies which cookies to forward to the origin for this cache behavior: all, none, or the list of cookies specified in the WhitelistedNames complex type.

                Amazon S3 doesn't process cookies. When the cache behavior is forwarding requests to an Amazon S3 origin, specify none for the Forward element.

                Possible values include:
                • "none"
                • "whitelist"
                • "all"
              • WhitelistedNames — (map)

                Required if you specify whitelist for the value of Forward:. A complex type that specifies how many different cookies you want CloudFront to forward to the origin for this cache behavior and, if you want to forward selected cookies, the names of those cookies.

                If you specify all or none for the value of Forward, omit WhitelistedNames. If you change the value of Forward from whitelist to all or none and you don't delete the WhitelistedNames element and its child elements, CloudFront deletes them automatically.

                For the current limit on the number of cookie names that you can whitelist for each cache behavior, see Amazon CloudFront Limits in the AWS General Reference.

                • Quantity — required — (Integer)

                  The number of different cookies that you want CloudFront to forward to the origin for this cache behavior.

            • Headers — (map)

              A complex type that specifies the Headers, if any, that you want CloudFront to vary upon for this cache behavior.

              • Quantity — required — (Integer)

                The number of different headers that you want CloudFront to forward to the origin for this cache behavior. You can configure each cache behavior in a web distribution to do one of the following:

                • Forward all headers to your origin: Specify 1 for Quantity and * for Name.

                  If you configure CloudFront to forward all headers to your origin, CloudFront doesn't cache the objects associated with this cache behavior. Instead, it sends every request to the origin.

                • Forward a whitelist of headers you specify: Specify the number of headers that you want to forward, and specify the header names in Name elements. CloudFront caches your objects based on the values in all of the specified headers. CloudFront also forwards the headers that it forwards by default, but it caches your objects based only on the headers that you specify.

                • Forward only the default headers: Specify 0 for Quantity and omit Items. In this configuration, CloudFront doesn't cache based on the values in the request headers.

              • Items — (Array<String>)

                A complex type that contains one Name element for each header that you want CloudFront to forward to the origin and to vary on for this cache behavior. If Quantity is 0, omit Items.

            • QueryStringCacheKeys — (map)

              A complex type that contains information about the query string parameters that you want CloudFront to use for caching for this cache behavior.

              • Quantity — required — (Integer)

                The number of whitelisted query string parameters for this cache behavior.

              • Items — (Array<String>)

                (Optional) A list that contains the query string parameters that you want CloudFront to use as a basis for caching for this cache behavior. If Quantity is 0, you can omit Items.

          • TrustedSigners — required — (map)

            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.

            • Enabled — required — (Boolean)

              Specifies whether you want to require viewers to use signed URLs to access the files specified by PathPattern and TargetOriginId.

            • Quantity — required — (Integer)

              The number of trusted signers for this cache behavior.

            • Items — (Array<String>)

              Optional: A complex type that contains trusted signers for this cache behavior. If Quantity is 0, you can omit Items.

          • ViewerProtocolPolicy — required — (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: 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.
            Possible values include:
            • "allow-all"
            • "https-only"
            • "redirect-to-https"
          • MinTTL — required — (Integer)

            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).

          • AllowedMethods — (map)

            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.

            • Quantity — required — (Integer)

              The number of HTTP methods that you want CloudFront to forward to your origin. Valid values are 2 (for GET and HEAD requests), 3 (for GET, HEAD, and OPTIONS requests) and 7 (for GET, HEAD, OPTIONS, PUT, PATCH, POST, and DELETE requests).

            • Items — required — (Array<String>)

              A complex type that contains the HTTP methods that you want CloudFront to process and forward to your origin.

            • CachedMethods — (map)

              A complex type that controls whether CloudFront caches the response to requests using the specified HTTP methods. There are two choices:

              • CloudFront caches responses to GET and HEAD requests.

              • CloudFront caches responses to GET, HEAD, and OPTIONS requests.

              If you pick the second choice for your Amazon S3 Origin, you may need to forward Access-Control-Request-Method, Access-Control-Request-Headers, and Origin headers for the responses to be cached correctly.

              • Quantity — required — (Integer)

                The number of HTTP methods for which you want CloudFront to cache responses. Valid values are 2 (for caching responses to GET and HEAD requests) and 3 (for caching responses to GET, HEAD, and OPTIONS requests).

              • Items — required — (Array<String>)

                A complex type that contains the HTTP methods that you want CloudFront to cache responses to.

          • SmoothStreaming — (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.

          • DefaultTTL — (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. For more information, see Specifying How Long Objects and Errors Stay in a CloudFront Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.

          • MaxTTL — (Integer)

            The maximum 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 adds HTTP headers such as Cache-Control max-age, Cache-Control s-maxage, and Expires to objects. For more information, see Specifying How Long Objects and Errors Stay in a CloudFront Edge Cache (Expiration) in the Amazon CloudFront Developer Guide.

          • Compress — (Boolean)

            Whether you want CloudFront to automatically compress certain files for this cache behavior. If so, specify true; if not, specify false. For more information, see Serving Compressed Files in the Amazon CloudFront Developer Guide.

          • LambdaFunctionAssociations — (map)

            A complex type that contains zero or more Lambda function associations for a cache behavior.

            • Quantity — required — (Integer)

              The number of Lambda function associations for this cache behavior.

            • Items — (Array<map>)

              Optional: A complex type that contains LambdaFunctionAssociation items for this cache behavior. If Quantity is 0, you can omit Items.

              • LambdaFunctionARN — (String)

                The ARN of the Lambda function.

              • EventType — (String)

                Specifies the event type that triggers a Lambda function invocation. Valid values are:

                • viewer-request

                • origin-request

                • viewer-response

                • origin-response

                Possible values include:
                • "viewer-request"
                • "viewer-response"
                • "origin-request"
                • "origin-response"
      • CustomErrorResponses — (map)

        A complex type that controls the following:

        • 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.

        For more information about custom error pages, see Customizing Error Responses in the Amazon CloudFront Developer Guide.

        • Quantity — required — (Integer)

          The number of HTTP status codes for which you want to specify a custom error page and/or a caching duration. If Quantity is 0, you can omit Items.

        • Items — (Array<map>)

          A complex type that contains a CustomErrorResponse element for each HTTP status code for which you want to specify a custom error page and/or a caching duration.

          • ErrorCode — required — (Integer)

            The HTTP status code for which you want to specify a custom error page and/or a caching duration.

          • ResponsePagePath — (String)

            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. 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 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.

          • ResponseCode — (String)

            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. If you don't want to specify a value, include an empty element, <ResponseCode>, in the XML document.

          • ErrorCachingMinTTL — (Integer)

            The minimum amount of time, in seconds, that you want CloudFront to cache the HTTP status code specified in ErrorCode. When this time period has elapsed, CloudFront queries your origin to see whether the problem that caused the error has been resolved and the requested object is now available.

            If you don't want to specify a value, include an empty element, <ErrorCachingMinTTL>, in the XML document.

            For more information, see Customizing Error Responses in the Amazon CloudFront Developer Guide.

      • Comment — required — (String)

        Any comments you want to include about the distribution.

        If you don't want to specify a comment, include an empty Comment element.

        To delete an existing comment, update the distribution configuration and include an empty Comment element.

        To add or change a comment, update the distribution configuration and specify the new comment.

      • Logging — (map)

        A complex type that controls whether access logs are written for the distribution.

        For more information about logging, see Access Logs in the Amazon CloudFront Developer Guide.

        • Enabled — required — (Boolean)

          Specifies whether you want CloudFront to save access logs to an Amazon S3 bucket. If you do not want to enable logging when you create a distribution or if you want to disable logging for an existing distribution, specify false for Enabled, and specify empty Bucket and Prefix elements. If you specify false for Enabled but you specify values for Bucket, prefix, and IncludeCookies, the values are automatically deleted.

        • IncludeCookies — required — (Boolean)

          Specifies whether you want CloudFront to include cookies in access logs, specify true for IncludeCookies. If you choose to include cookies in logs, CloudFront logs all cookies regardless of how you configure the cache behaviors for this distribution. If you do not want to include cookies when you create a distribution or if you want to disable include cookies for an existing distribution, specify false for IncludeCookies.

        • Bucket — required — (String)

          The Amazon S3 bucket to store the access logs in, for example, myawslogbucket.s3.amazonaws.com.

        • Prefix — required — (String)

          An optional string that you want CloudFront to prefix to the access log filenames for this distribution, for example, myprefix/. If you want to enable logging, but you do not want to specify a prefix, you still must include an empty Prefix element in the Logging element.

      • PriceClass — (String)

        The price class that corresponds with the maximum price that you want to pay for CloudFront service. If you specify PriceClass_All, CloudFront responds to requests for your objects from all CloudFront edge locations.

        If you specify a price class other than PriceClass_All, CloudFront serves your objects from the CloudFront edge location that has the lowest latency among the edge locations in your price class. Viewers who are in or near regions that are excluded from your specified price class may encounter slower performance.

        For more information about price classes, see Choosing the Price Class for a CloudFront Distribution in the Amazon CloudFront Developer Guide. For information about CloudFront pricing, including how price classes map to CloudFront regions, see Amazon CloudFront Pricing.

        Possible values include:
        • "PriceClass_100"
        • "PriceClass_200"
        • "PriceClass_All"
      • Enabled — required — (Boolean)

        Specifies whether you want CloudFront to save access logs to an Amazon S3 bucket.

        If you do not want to enable logging when you create a distribution, or if you want to disable logging for an existing distribution, specify false for Enabled, and specify empty Bucket and Prefix elements.

        If you specify false for Enabled but you specify values for Bucket and Prefix, the values are automatically deleted.

      • ViewerCertificate — (map)

        A complex type that specifies the following:

        • Which SSL/TLS certificate to use when viewers request objects using HTTPS

        • Whether you want CloudFront to use dedicated IP addresses or SNI when you're using alternate domain names in your object names

        • The minimum protocol version that you want CloudFront to use when communicating with viewers

        For more information, see Using an HTTPS Connection to Access Your Objects in the Amazon Amazon CloudFront Developer Guide.

        • CloudFrontDefaultCertificate — (Boolean)
        • IAMCertificateId — (String)
        • ACMCertificateArn — (String)
