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 in the Amazon CloudFront Developer Guide (quotas were formerly referred to as limits).

Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as cloudfront from '@aws-cdk/aws-cloudfront';
const originProperty: cloudfront.CfnDistribution.OriginProperty = {
  domainName: 'domainName',
  id: 'id',

  // the properties below are optional
  connectionAttempts: 123,
  connectionTimeout: 123,
  customOriginConfig: {
    originProtocolPolicy: 'originProtocolPolicy',

    // the properties below are optional

    httpsPort: 123,
    originKeepaliveTimeout: 123,
    originReadTimeout: 123,
    originSslProtocols: ['originSslProtocols'],
  },
  originAccessControlId: 'originAccessControlId',
  originCustomHeaders: [{
    headerName: 'headerName',

originPath?	`string`	An optional path that CloudFront appends to the origin domain name when CloudFront requests content from the origin.
originShield?	`IResolvable` `\|` `OriginShieldProperty`	CloudFront Origin Shield. Using Origin Shield can help reduce the load on your origin.
s3OriginConfig?	`S3OriginConfigProperty` `\|` `IResolvable`	Use this type to specify an origin that is an Amazon S3 bucket that is not configured with static website hosting.

domainName

Type: string

The domain name for the origin.

For more information, see Origin Domain Name in the Amazon CloudFront Developer Guide .

id

Type: string

A unique identifier for the origin. This value must be unique within the distribution.

Use this value to specify the TargetOriginId in a CacheBehavior or DefaultCacheBehavior .

connectionAttempts?

Type: number (optional)

The number of times that CloudFront attempts to connect to the origin.

The minimum number is 1, the maximum is 3, and the default (if you don't specify otherwise) is 3.

For a custom origin (including an Amazon S3 bucket that's configured with static website hosting), this value also specifies the number of times that CloudFront attempts to get a response from the origin, in the case of an Origin Response Timeout .

For more information, see Origin Connection Attempts in the Amazon CloudFront Developer Guide .

connectionTimeout?

Type: number (optional)

The number of seconds that CloudFront waits when trying to establish a connection to the origin.

The minimum timeout is 1 second, the maximum is 10 seconds, and the default (if you don't specify otherwise) is 10 seconds.

For more information, see Origin Connection Timeout in the Amazon CloudFront Developer Guide .

customOriginConfig?

Type: CustomOriginConfigProperty | IResolvable (optional)

Use this type to specify an origin that is not an Amazon S3 bucket, with one exception.

If the Amazon S3 bucket is configured with static website hosting, use this type. If the Amazon S3 bucket is not configured with static website hosting, use the S3OriginConfig type instead.

originAccessControlId?

Type: string (optional)

The unique identifier of an origin access control for this origin.

For more information, see Restricting access to an Amazon S3 origin in the Amazon CloudFront Developer Guide .

originCustomHeaders?

Type: IResolvable | IResolvable | OriginCustomHeaderProperty[] (optional)

A list of HTTP header names and values that CloudFront adds to the requests that it sends to the origin.

For more information, see Adding Custom Headers to Origin Requests in the Amazon CloudFront Developer Guide .

originPath?

Type: string (optional)

An optional path that CloudFront appends to the origin domain name when CloudFront requests content from the origin.

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

originShield?

Type: IResolvable | OriginShieldProperty (optional)

CloudFront Origin Shield. Using Origin Shield can help reduce the load on your origin.

For more information, see Using Origin Shield in the Amazon CloudFront Developer Guide .

s3OriginConfig?

Type: S3OriginConfigProperty | IResolvable (optional)

Use this type to specify an origin that is an Amazon S3 bucket that is not configured with static website hosting.

To specify any other type of origin, including an Amazon S3 bucket that is configured with static website hosting, use the CustomOriginConfig type instead.
