iCal / ics Feed错误

Question

I am trying to create a feed of events from my website but getting an error in iCal when I try to import. I would like it to be a feed user's subscribe to to have events automatically added to iCal or Outlook.

I am sending these headers:

Content-Type: text/Calendar
Content-Disposition: inline; filename=ical.ics

And here is the contents of the file being generated. Right now it only has a single event but eventually it will have multiple BEGIN:VEVENT.
