aws_cloudfront_distribution forwarded_values (Terraform) 中 headers 的语法是什么?

What is the syntax for headers in aws_cloudfront_distribution forwarded_values (Terraform)?

doc 没有显示示例,所以我不清楚。应该怎样才合适?

resource "aws_cloudfront_distribution" "this" {
  ...
  default_cache_behavior {
    max_ttl = 86400

    forwarded_values {
      # which option?
      headers      = ["Cache-Control max-age"]
      headers      = ["Cache-Control: max-age"]        
      headers      = ["Cache-Control-max-age"]
      headers      = ["something else?"]
      ....

header Cache-Control: max-age=86400 具有键:Cache-Control 和值:max-age=86400。您只需使用名称 Cache-Control,无需 max-age 部分。
