      2) We use ClientLogin to obtain an AUTH token for the user
         (see http://code.google.com/apis/accounts/AuthForInstalledApps.html).
      3) We pass the auth token to /_ah/login on the server to obtain an
         authentication cookie. If login was successful, it tries to redirect
         us to the URL we provided.
 
     If we attempt to access the upload API without first obtaining an
     authentication cookie, it returns a 401 response (or a 302) and
     directs us to authenticate ourselves with ClientLogin.
