How to automatically reload TYPO3 calendar from external ics

Hi I'm using the calendar base extension (cal) for displaying my calendar in a TYPO3 website.

I conf开发者_开发技巧igured an external calendar and it imports all events correctly. How can I automatically reload the events from this external ics-calendar?

thanks!

For TYPO3 4.3 and up, you'll want to use the scheduler extension. Once its installed, you'll find a task inside the scheduler module for updating external calendars.
