title: Is it possible to upload to S3 directly from URL using POST?
body: <p>I know there is a way to upload to S3 directly from the web browser using POST without the files going to your backend server. But is there a way to do it from URL instead of web browser.</p>
  
  <p>Example, upload a file that resides at <a href="http://example.com/dude.jpg">http://example.com/dude.jpg</a> directly to S3 using post. I mean I don't want to download the asset to my server then upload it to S3. I just want to make a POST request to S3 and it uploads it automatically.</p>
