I have a calendar feed (using the Drupal Calendar module) on a site and I'd like to add this calendar to Google Calendar. I have this working for a publicly accessible calendar and it works fine.
The problem now is that my calendar is only accessible for authenticated users and should remain so. I see no way to authenticate the application accessing a feed and therefore can't access that calendar from Google Calendar.
Is there any way to provide credentials in the feed url or something similar?
