title: Cloudfront max-age together with TTL usefull?
body: <p>For a image gallery I use amazon cloudfront. </p>
  
  <p>I have set at the origin:</p>
  
  <pre><code>Cache-Control:max-age=31536000 (1 Year)
  </code></pre>
  
  <p><strong>1</strong>. Is it usefull to set the TTL 0 (24 hours) to 1 Year <strong>too</strong> when I have already set the max-age? </p>
  
  <p><strong>2</strong>. Will amazon check the file with TTL0 every 24 hours when I have set the max-age to 1 year?</p>
  
  <p><em>Amazon is saying:</em></p>
  
  <pre><code>Objects are cached for the greater of the value of the Cache-Control max-age directive or the value of the CloudFront Minimum TTL
  </code></pre>
  
  <p><em>Amazon is also saying:</em></p>
  
  <pre><code>If an object in an edge location isn't frequently requested, CloudFront might evict the object—remove the object before its expiration date—to make room for objects that are more popular.
  </code></pre>
  
  <p>In that case, I think its usefull to set TTL to year, because the images will stay for sure and not before? Please correct me.</p>
  
  <p>Thanks for clarification. </p>
