title: Locally testing a Facebook app via OAuth login on Google app engine
body: <p>I am using <code>dev_appserver.py</code> to test my app locally.  However, I can't login to it because Facebook restricts logins to only the app URL I provide in the Facebook setup, which is <code>myappname.appspot.com</code>.</p>
  
  <p>It doesn't look like there's a way to authorize secondary referrers for Facebook apps.  Are there any good workarounds for this?  </p>
  
  <p>My app relies almost entirely on Facebook data, so faking a login won't get me very far.</p>
