Redirect *.appspot.com To Custom Domain: Google App Engine (django)

I'm directly putting here some sample code of mine to get better picture. url.py (r'^robots\.txt$', 'myapp.views.robots'), (r'^$', 'myapp.views.home'), views.py def home(request

<link rel="canonical" href="https://example.com/" />
