2.2. Internet Calendar Subscriptions

An Internet calendar subscription is simply an iCalendar data file made available on a web server. However, rather than using a web browser to download the calendar data, calendar clients can instead use the URL to the calendar data on the web server to download the calendar data themselves. Additionally, the clients can check the web server on a regular basis for updates to the calendar data, and then update their own cached copy of it. This allows calendar data that changes over time to be kept synchronized.
