title: How to set an AWS S3 object to never expire in Django Storages?
body: <p>I am using <a href="http://django-storages.readthedocs.io/en/latest/backends/amazon-S3.html" rel="nofollow noreferrer">django-storage</a> (which uses Boto3 internally) to upload images. I am successfully able to do so and the return URL I get is of this format: </p>
  
  <p><a href="https://&lt;bucket-name&gt;.s3.amazonaws.com/foo.jpg?Signature=&lt;my-singnature&gt;&amp;AWSAccessKeyId=&lt;my-accesss-key&gt;&amp;Expires=1513089114" rel="nofollow noreferrer">https://.s3.amazonaws.com/foo.jpg?Signature=&amp;AWSAccessKeyId=&amp;Expires=1513089114</a></p>
  
  <p>where Signature and AWSAccessKeyId are filled in as well.</p>
  
  <p>Now, I need to give this URL directly to Mobile Developers and I can't have the timeout set so late. I need it for many years or potentially always accessible. What is a good way to do so? What is the solution</p>
