ALB now supports for modifying host header and URL information. This feature has already supporrted by cloudformation.
https://docs.aws.amazon.com/ja_jp/elasticloadbalancing/latest/application/rule-transforms.html

• Add new ListenerTransform class with factory methods:
  • hostHeaderRewrite(): Transform host headers using regex
    patterns
  • urlRewrite(): Transform URL paths using regex patterns
• Add transforms property to AddApplicationActionProps
• Add addTransform() method to ApplicationListenerRule
• Implement validation logic:

  • Maximum one host header rewrite and one URL rewrite per
    rule
  • Exactly one rewrite rule per transform

Because checkAddRuleProps() cannot accept transforms prop, I've added new validation function checkAddActionProps().

[badmintoncryer]

In CloudFormation, an array of rewrite rules can be configured, but currently, deploying with multiple rules results in an error.
To prepare for future enhancements, the parameter is defined to accept an array, while validation restricts the number of elements to one.

      transforms: [
        elbv2.ListenerTransform.hostHeaderRewrite([
          {
            regex: '^(.*)\\.example\\.com$',
            replace: '$1.internal.example.com',
          },
          {
            regex: '^(.*)$',
            replace: 'internal.example.com',
          },
        ]),
      ],
