title: How can I force Filepicker.io to send Cache-Control headers to Amazon S3?
body: <p>I'm using Filepicker.io and Django with the <a href="https://github.com/Filepicker/django-filepicker" rel="nofollow">official library</a> and I've noticed two things:</p>
  
  <ul>
  <li>The URLs it provides to Django are direct to my S3 bucket, not the Filepicker URLs.</li>
  <li>It doesn't set any caching on the files it sends whatsoever.</li>
  </ul>
  
  <p>Since I'm using this mainly for images which will be reloaded kinda often, I'm wondering how I can make Filepicker set Cache-Control headers.</p>
  
  <p>Alternatively, is it possible to force Amazon S3 to set Cache-Control headers on every single object that goes into a bucket automatically?</p>
