Capturing Responses from iCal/ics file

Question

I am generating ics/iCal files for events in a Web app and emailing them to users to add to their calendars. This part works great

I would like to require a response in the ics files and then capture their responses. I was under the impression I can specify a URL to my Web app in the ics file. Then I can parse the email and attendee status from the response format.

Is something like this possible? I can't find any ics documentation to handle something like this.

Thanks!

Unfortunately, this is not possible. It's possible to specify in an iCalendar object that a user should respond, (by using the relevant parameters in the ATTENDEE property), but the result will be sent back as an e-mail response.

unless the receiving user runs a caldav server with scheduling support.
