How can i connect different Google App Engine Version urls to A different domain name?

Question

When you upload a new version to app engine, let's call it '0001', you can send requests to this version directly using this url: http://0001.myapp.appspot.com

I find it very useful and I made an habit to release my web apps pointing to the corresponding server version. So when I upload version 0002 to the app engine it points to http://0002.myapp.appspot.com , the same goes to version 0003: http://0003.myapp.appspot.com .

My Challenge is that; when i want to link them to custom domains like;

• Version 0001 to be linked to http://www.money.com .
• Version 0002 to be linked to http://app.money.com .
• And Version 0003 to be linked to http://www.facebook.com .

Instead it links the entire AppId "myapp" to "www.money.com". How do i point them to different domians?

What you're looking for is called " services " on App Engine (formerly known as modules ). Each service can have own version, but you should use it only for development/testing purposes.

Basically your app config have <module> option:

<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
  <application>my-app</application>
  <module>mymodule</module>
  <version>0002</version>
</appengine-web-app>

You can have different modules deployed on same time, but mapped to different urls/domains by using dispatch.xml file:

<dispatch-entries>
  <dispatch>
      <url>app.money.com/</url>
      <module>mymodule</module>
  </dispatch>
</dispatch-entries>
