Interface ISourceConfiguration
A source configuration is a wrapper for CloudFront origins and behaviors.
Namespace: Amazon.CDK.AWS.CloudFront
Assembly: Amazon.CDK.Lib.dll
Syntax (csharp)
public interface ISourceConfigurationSyntax (vb)
Public Interface ISourceConfigurationRemarks
An origin is what CloudFront will "be in front of" - that is, CloudFront will pull its 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.

Properties
| Behaviors | The behaviors associated with this source. |
| ConnectionAttempts | The number of times that CloudFront attempts to connect to the origin. |
| ConnectionTimeout | The number of seconds that CloudFront waits when trying to establish a connection to the origin. |
| CustomOriginSource | A custom origin source - for all non-s3 sources. |
| FailoverCriteriaStatusCodes | HTTP status code to failover to second origin. |
| FailoverCustomOriginSource | A custom origin source for failover in case the s3OriginSource returns invalid status code. |
| FailoverS3OriginSource | An s3 origin source for failover in case the s3OriginSource returns invalid status code. |
| OriginShieldRegion | When you enable Origin Shield in the AWS Region that has the lowest latency to your origin, you can get better network performance. |
| S3OriginSource | An s3 origin source - if you're using s3 for your assets. |
Properties
Behaviors
The behaviors associated with this source.
IBehavior[] Behaviors { get; }Property Value
Remarks
At least one (default) behavior must be included.
ConnectionAttempts
The number of times that CloudFront attempts to connect to the origin.
double? ConnectionAttempts { get; }Property Value
Remarks
You can specify 1, 2, or 3 as the number of attempts.
Default: 3
ConnectionTimeout
The number of seconds that CloudFront waits when trying to establish a connection to the origin.
Duration? ConnectionTimeout { get; }Property Value
Remarks
You can specify a number of seconds between 1 and 10 (inclusive).
Default: cdk.Duration.seconds(10)
CustomOriginSource
A custom origin source - for all non-s3 sources.
ICustomOriginConfig? CustomOriginSource { get; }Property Value
Remarks
An origin is what CloudFront will "be in front of" - that is, CloudFront will pull its 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.
ExampleMetadata: fixture=_generated
FailoverCriteriaStatusCodes
HTTP status code to failover to second origin.
FailoverStatusCode[]? FailoverCriteriaStatusCodes { get; }Property Value
Remarks
Default: [500, 502, 503, 504]
FailoverCustomOriginSource
A custom origin source for failover in case the s3OriginSource returns invalid status code.
ICustomOriginConfig? FailoverCustomOriginSource { get; }Property Value
Remarks
Default: - no failover configuration
FailoverS3OriginSource
An s3 origin source for failover in case the s3OriginSource returns invalid status code.
IS3OriginConfig? FailoverS3OriginSource { get; }Property Value
Remarks
Default: - no failover configuration
OriginShieldRegion
When you enable Origin Shield in the AWS Region that has the lowest latency to your origin, you can get better network performance.
string? OriginShieldRegion { get; }Property Value
Remarks
Default: - origin shield not enabled
See: https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/origin-shield.html
S3OriginSource
An s3 origin source - if you're using s3 for your assets.
IS3OriginConfig? S3OriginSource { get; }Property Value
Remarks
An origin is what CloudFront will "be in front of" - that is, CloudFront will pull its 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.
