I am trying to dynamically create iCalendar or vCalendar files. I can do this with a Zope Page Template, naming it myCalendar.ics. When myCalendar.ics is accessed through a web browser, iCal pops up and asks what I want to do with the calendar info, etc. and all is well. But what I would like to do is use iCal or thunderbird( lightening ) to subscribe to the calendar so that updates are handled automatically. For iCal to do this, it wants to access the ics file via webdav. So I attempt to connect to zope via its webdav port and request the sale zpt, but of course it sends it as its source, not as the rendered calendar. If i take out all the TAL and just have a static vCalendar or iCalendar file then this works via webdav but my whole reason for doing this is so that I can populate the calendar with events form a RDBMS when the myCalendar.ics template is called. Your ideas appreciated.
