Ok that brings up a couple of questions: First, how do i actually send a HTTP PUT? And to what url do i send the request? My calendarserver can be seen locally at calserver:8008. Is that where I send the request to? And Assuming the example i put below is the correct format, what's the correct PUT path to put in PUT /home/lisa/calendars/events/ qwue23489.ics HTTP/1.1? PUT /home/lisa/calendars/events/qwue23489.ics HTTP/1.1 If-None-Match: * Host: calserver Content-Type: text/calendar Content-Length: xxxx BEGIN:VCALENDAR VERSION:2.0 PRODID:-//Example Corp.//CalDAV Client//EN BEGIN:VEVENT UID:20010712T182145Z-123401@example.com DTSTAMP:20080910T175147Z DTSTART:20080910T175147Z DTEND:20080910T195147Z SUMMARY:A Test END:VEVENT END:VCALENDAR Thanks
