title: Sending "Cache-Control : no-cache" from cloudfront
body: <p>I have a file, stored on S3, let's say index.html which is changing once in a while.</p>
  
  <p>I don't want end customer to cache it, so I want to send a http header <code>max-age=0, no-store, no-cache, must-revalidate</code>.</p>
  
  <p>From what I understand from the doc, if I set this header in S3 metadata, Cloudfront will respect this header, which means Cloudfront will always reread the file for each request.</p>
  
  <p>I don't want Cloudfront to do that, I am happy to invalidate Cloudfront whenever the file has changed.</p>
  
  <p>Is that possible?</p>
