title: Cannot embed Google Drive Files in an iframe
body: <p>I recently had a problem with the Google Drive API displaying my documents. We have developed a web application that is connecting to Google Drive accounts to retrieve a user's drive files, then display in an iframe the file using its embedUrl/alternateUrl. </p>
  
  <p>This has worked fine for us in the past, but suddenly files other than Google Documents stopped displaying: html files, text files, doc files... even images! </p>
  
  <p>The error I get is <code>Refused to display 'https://docs.google.com/file/d/0B_JkNS6Wu4b5R2c0YlJSN0oyQUE/edit?usp=drivesdk' in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'.</code> </p>
  
  <p>I understand the error, it means that Google is preventing the display of documents outside of the Google domain, but the question is "why suddenly now", and how to circumvent it.</p>
  
  <p>If someone stumbled upon the same issue and have found a solution, I'd be glad to hear.</p>
  
  <p>Thank you kindly. </p>
