I have a GAE app (Aggregate web site) at the url projectname.appspot.com
Now, I bought a domain mydomain.com from LWS and I want to map the subdomain projectname.mydomain.com to projectname.appspot.com
After setting all the required steps suggested by GAE, I'm able to reach my GAE app via projectname.mydomain.com; but, once the page finishes loading, instead of the new url (my hope), the old one (projectname.appspot.com) still displaying in the address bar of my browser.
