title: Local domain and sub domain mapping (web development)
body: <p>Under Linux what are the options for implementing a domain and subdomain mapping for a Google App Engine web application during development mode. </p>
  
  <ul>
  <li>Is there like a on-the-fly domain mapping where I don't have to deal with modifying Linux network properties manually? </li>
  </ul>
  
  <p>I have a GAE where the I need to make this subdomain mapping based on some hash or username like: </p>
  
  <p><code>http://username.myapp.com</code> (Local)</p>
  
  <p>Where it is also accessible through <code>http://myapp.com/username</code></p>
  
  <p>Right now I can access such resource through: <code>http://127.0.0.1:8888/somename</code></p>
  
  <p>However, right now I really need to test it with such mapping.</p>
