  <li><p>In GAE, the url match patterns are evaluated in the order they appear, first come first serve. Is it the same case in Flask?</p></li>
  <li><p>In Flask, how to write a url match pattern to deal with all other unmatched urls. In GAE, you only need to put <code>/.*</code> in the end, like: <code>('/.*', Not_Found)</code>. How to do the same thing in Flask since Flask wont support Regex.</p></li>
