title: Add HTTP Strict Transport Security (HSTS) in AWS Gateway (REST API)
body: <p>Our security team wants all our Rest API on AWS to have HTTP Strict Transport Security (HSTS) header set, even though our api's are not called from any webpages.</p>
  <p>I have found some use cases on setting response headers in Lambda response but most of our api's are linked to SQS or SNS. So i'm not sure how to add this response header in AWS API GW.</p>
  <p>Can anyone guide me on this.</p>
