title: Upload file bigger than 40MB to Google App Engine?
body: <p>I am creating a Google App Engine web app to "transform" files of 10K~50M</p>
  
  <p><b>Scenario:</b></p>
  
  <ol>
  <li>User opens <a href="http://fixdeck.appspot.com" rel="noreferrer">http://fixdeck.appspot.com</a> in web browser</li>
  <li>User clicks on "Browse", select file, submits</li>
  <li>Servlet loads file as an InputStream</li>
  <li>Servlet transforms file</li>
  <li>Servlet saves file as an OutputStream</li>
  <li>The user's browser receives the transformed file and asks where to save it, directly as a response to the request in step 2</li>
  </ol>
  
  <p>(For now I did not implement step 4, the servlet sends the file back without transforming it.)</p>
  
  <p><b>Problem:</b> It works for 15MB files but not for a 40MB file, saying: <i>"Error: Request Entity Too Large. Your client issued a request that was too large."</i></p>
  
  <p>Is there any workaround against this?</p>
