title: CalDAV faster than .ics files for calendar syncing?
body: <p>Would a CalDAV server provide faster syncing than .ics files?  Specifically for iOS and Google Calendar.  I realize the client is responsible for updating and frequency.</p>
  
  <p>Many posts indicate Google Calendar is slow to update .ics feeds. I tested and after 6+hrs, it still hadn't updated the changes I made to the .ics file.</p>
  
  <p>Same issue with iOS. Initial load of the .ics file loads the calendar fine. But after changes to the .ics file, iOS never makes another request for the file again for days (watching apache log file).</p>
  
  <p>I'm trying to share a calendar feed. I only need to post the calendar (read-only). I don't need the user to make changes. .ics seems easier than running a full CalDAV server. If I do, is it worth it? Will it sync to Google Calendar, iOS, and other clients quickly (minutes, not days)?</p>
