title: Cloudfront caching with signed URLs-- does it cache the resource regardless of signature?
body: <p>We're caching some S3 bucket content using Cloudfront.  Our URLs to these assets are signed, with an expiration date of 24 hours after they've been generated.</p>
  <p>So after one day our customers would need to hit an API endpoint of ours to generate a new signature to gain access to those assets.  However, we would like for cloudfront to cache those assets for longer than 24 hours, regardless of the URL signature-- that way we'll minimize cache misses from Cloudfront and the clients will get content quicker.  Is this possible and if so, what settings should I be looking at in Cloudfront / S3?</p>
