Question

I have a domain example.com. I have a S3 bucket named example.com setup with an index.html file that works. Now I like to create two s

If you are using CDK to create a CloudFrontWebDistribution with an S3 source, then your first guess is probably to do this:

                OriginConfigs = new[] {
                    new SourceConfiguration {
                        S3OriginSource = new S3OriginConfig
                        {
                            S3BucketSource = bucket
                        }
                        Behaviors = new[] { new Behavior { IsDefaultBehavior = true } }
                    }
                }

However, to configure cloudfront to use the website-bucket-url (that does have the behavior to resolve a directory to index.html), you need to use:

                OriginConfigs = new[] {
                    new SourceConfiguration {
                        CustomOriginSource = new CustomOriginConfig
                        {
                            DomainName = bucket.BucketWebsiteDomainName,
                            OriginProtocolPolicy = OriginProtocolPolicy.HTTP_ONLY
                        },
                        Behaviors = new[] { new Behavior { IsDefaultBehavior = true } }
                    }
                }

You need to specify the protocol as HTTP_ONLY because website buckets do not support HTTPS. The default for a CustomOriginSource is HTTPS_ONLY.
