title: How to set a subdomain as 'sub.domain.appspot.com' on google app engine?
body: <p>I know how to set up an app on google app engine as myapp.appspot.com, but I hope to use a.myapp.appspot.com and b.myall.appspot.com for different interfaces of the same app. As google instruction said, this is supported:</p>
  <blockquote>
  <p>appspot.com domains also support subdomains of the form subdomain.your_app_id.appspot.com, where subdomain can be any string allowed in one part of a domain name (not .). Requests sent to any subdomain in this way are routed to your application.</p>

  </blockquote>
  <p>But I cannot figure it out how to set up. Has anyone ever created subdomain on appspot?</p>
