Question

Here is what I’d like to achieve

http://foo.somedomain.com gets handled by
http://myapp.appspot.com/foo (google appengine app myapp)
and the underlying url is masked.

Note the following:

• somedomain.com is a third party domain that would like to add foo.somedomain.com
• mydomain.com would be CNAME’d to myapp.appspot.com
• mydomain.com/foo would point to myapp.appspot.com/foo

other scenarios

1. can foo.mydomain.com be made to point to myapp.appsot.com/foo
2. can foo.somedomain.com point directly to myapp.appspot.com/foo

Added: myapp.appspot.com is developed using django w/ app-engine-patch

Answer 1

You can’t do this in the way described. In order to do this, you need to:

1. CNAME foo.somedomain.com to ghs.google.com (not to myapp.appspot.com)
2. Set up Google Apps for your Domain on somedomain.com, if it’s not already
3. Add the app ‘myapp’ to foo.somedomain.com through the Apps control panel

Once that’s done, your app can check self.request.host to determine which hostname was sent, and route requests appropriately.
