sample code create calendar event. want send reschedule calendar event scheduled calendar. other alternative tried send cancellation mail service , 1 time again send new calendar event. required send 2 different mail. there way can in single mail.

the key to:

keep same uid in initial request bump sequence (and dtstamp)

i noticed in code that, although correctly setting method:request in icalendar stream, content-type still indicates method=cancel.
