Question: Access ctag from ical #243

Closed samuelstein closed 4 years ago

samuelstein commented 4 years ago

Is there a possibility to access the ctag from the ical feed to determine if the calendar has changed?

s0600204 commented 4 years ago

ctag is not a valid iCal component, property, or data value type, so no.

Whilst the parser can read calendar data from a myriad of sources (including URLs), it expects whatever it's passed to contain or point at calendar data directly, not to some API or object dealing with metadata.

okay, this i didn't knew. is there a other common way to detect changes from calendars via caldav?
