…gent in local dev proxy Update the local dev proxy to conditionally forward the x-sfdc-access-control header to SCAPI proxy targets whose hostname matches a configured suffix list, mirroring the Lambda@Edge behavior from portal_app PRs 7680 and 7712. Also preserve the original User-Agent header in non-caching proxy requests instead of overwriting it with 'Amazon CloudFront'.
