403 error with SAMEORIGIN in header

[Mike]

I developing a mac desktop app and I'm just making the first steps to add a feature that will connect to a Django server.  I have the Django project running on the development server and the app running on the same machine.  When I try to call a Django project view from the app, on 127.0.0.1:8000, Django replies with a 403 error and this header:

    "Content-Type" = "text/html";

    Date = "Fri, 22 Jun 2012 16:43:27 GMT";

    Server = "WSGIServer/0.1 Python/2.7.1";

    "X-Frame-Options" = SAMEORIGIN;

This seems to have something to do with clickjacking protection but I'm not doing anything with iframes.  Is there any other reason why Django would return this error?
