title: Cloudfront how to avoid If-Modified-Since header request everytime
body: <p>AWS Cloudfront document says: </p>
  
  <blockquote>
    <p>If you set the TTL for a particular origin to 0, CloudFront will still
    cache the content from that origin. It will then make a GET request
    with an If-Modified-Since header, thereby giving the origin a chance
    to signal that CloudFront can continue to use the cached content if it
    hasn't changed at the origin</p>

  <p>I need to configure my Dynamic Content. I have already set TTL to 0.. I want every request to go to Origin always. Is there a way I avoid this additional GET request with an If-Modified-Since header ! Why this extra request everytime ! </p>
