rdates

The rdates parameter takes a semicolon-separated list of date-time specifications where each date-time gives a recurrence date of the event.

For example, the following rdates parameter specifies a recurring event with two recurrence dates (3/31/02 11:22:33 and 5/31/02 11:22:33):

rdates=20020331T112233;20020531T112233

The following example URL passes the rdates parameter:

http://webcalendarserver/storecomponents.wcap
              ?id=b5q2o8ve2rk02nv9t6
              &calid=jdoe
              &uid=333
              &dtstart=20020301T112233Z
              &rdates=20020331T112233;20020531T112233
              &dtend=20020301T112233
              &summary=uuuu

If you want to the change the recurrence rule after a certain date, you must set rchange to 1.
