Viewing a Flask app in the Cloud9 Test Browser
<p>I'm creating a web app based on Miguel Grinberg's Flasky app (from his book Flask Web Development). </p>

<p>When running <code>manage.py runserver</code> in the Cloud9 IDE, the command line tells me that it is running at <a href="http://127.0.0.1:5000/" rel="nofollow">http://127.0.0.1:5000/</a>. However, when I type this IP address into the Cloud9 test browser, I see nothing. <a href="https://[workspace]-[username].c9users.io" rel="nofollow">https://[workspace]-[username].c9users.io</a> (with or without :5000) doesn't work either. </p>

<p>Here's my manage.py code:</p>

<pre><code>from app import create_app
from flask.ext.script import Manager, Shell

app = create_app('default')
manager = Manager(app)

if __name__ == '__main__':
  manager.run()
</code></pre>
