How does iCal / WebDev Calendar works?

Question

I tried to post in Apple Developer Forum but I got no luck for 6 days... I hope I get more here :)

I'm about to create a convert tool from a CRM application to ical format, witch works fine (I generate the correct code and is well imported, but I need more...), I wanted to know how does iCal App in the Mobile works.

How, after the first subscription, does the calendar "refresh" works?

when I change the file in the server, how can I PUSH the changes to the device? how long in long time does iCal checks the file on the server?

on the Mac there is a Refresh Rate that we can set up, but not on the iPhone (at least not on mine 3G with iOS 4.01).

Can anyone point me into the right track to know more about the sync procedures between the device and the ics file on the server? And How can I have both ways read/write, what do I need to have in my end (the one that have the ics file) to receive updates?

Thank you!

Answer 1

The new iCal server uses caldav protocol and practically that means that all devices are first rate client of the same server. There is no need of sync. Consider this like a shared repository that can be accessed by multiple clients
