title: Is there any way to route sub-domain to module in Google Appengine
body: <p>I configured my dispatch.yaml file to route /admin to Admin module. But I want to route my sub-domain to route the Admin module.
  My dispatch.yaml file contains the following code</p>
  
  <pre><code>- url: "*/admin"
    module: admin
  
  - url: "*/admin/*"
    module: admin
  </code></pre>
  
  <p>In admin module </p>
  
  <pre><code>app = webapp2.WSGIApplication([
      routes.DomainRoute('admin.knowyouroffers.in', [
          webapp2.Route('/', handler=Admin, name='home'),
      ]),debug=settings.debug)
  </code></pre>
  
  <p>I tried the following code in dispatch.yaml. But It couldn't work</p>
  
  <pre><code>- url: "admin.knowyouroffers.in/*"
    module: admin
  </code></pre>
