title: Uploading PDF to Amazon S3 and display in-browser
body: <p>I am uploading PDF's to AmazonS3 manually, using Panic Transmis and via a PHP script/API. 
  For some reason, some display in your browser, and some force download. 
  I have checked permission and can not seem to see any issues, Can anyone help explain how to make PDF's always display in browser ( unless the user specifies otherwise ). </p>
  
  <p>I don't think it is as browser issue.</p>
