title: Why I can not download GAE data? 302 error is returned
body: <p>I used the following command to download my GAE data:</p>
  
  <pre><code>appcfg.py download_data --log_file=bulkloader.log --kind=MyKind --url=http://myappid.appspot.com/rmt_api --filename=myfilename --db_filename=MyKind_db.sql3 --result_db_filename=MyKind_result_db.sql3 --config_file=bulkloader.yaml
  </code></pre>
  
  <p>It worked well a few days ago, but yesterday it returned me <code>access_token is expired</code>. I manually deleted gae oauth files at <code>/Users/myuser/</code> (I am on OSX), but it didn't help - now I get the following output:</p>
  
  <pre><code>09:51 PM Downloading data records.

  Error 302: --- begin server output ---
  
  --- end server output ---
  </code></pre>
  
  <p>I tried to add <code>--verbose</code> and <code>--noisy</code> parms, but nothing changed.</p>
  
  <p>In result I can not download the data. Upload of the application <code>appcfg.py --update</code> works well.</p>
  
  <p>It looks like GAE issue, but all such <a href="https://code.google.com/p/googleappengine/issues/detail?id=12435" rel="nofollow">issues</a> are rejected.</p>
