@markpeek Will you be able to review this please?

I do not see this supported in CloudFormation yet. Thank you for the PR and I will verify/merge after AWS implements it.

Thanks @markpeek AWS API documentation has details about ForwardConfig and I have tested that CFN template for Listener with ForwardConfig work perfectly.

https://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-listeners.html#forward-actions

However, I agree to you and I have asked AWS to update the documentation. Will update this thread accordingly.

Thanks @yks0000 for this update, this is something very useful for one of the projects I'm working on.

@markpeek I think the document you shared has a mention of using ForwardConfig:

"TargetGroupArn
The Amazon Resource Name (ARN) of the target group. Specify only when Type is forward and you want to route to a single target group. To route to one or more target groups, use ForwardConfig instead. "

I think the documentation still needs to be properly updated but looks like a quick fix from AWS for now.

AWS has opened a issue here to track it publicly

CloudFormation just updated their documentation to include ForwardConfig. Very excited about this!

Thanks! Appreciate the wait for it to be supported. I'm going to follow up with a couple of adjustments.
