Using curl without the @ didn't seem to work.
I see there is a Ruby Net/HTTP library that I could use to do a straight POST into Zimbra. This is the basic example from some Ruby documentation (Class: Net::HTTP)...
Can I use this to post calendar data into Zimbra or do I have to use curl? Anyone know how to POST an ics file into Zimbra? Something like this?
res = Net::HTTP.post_form(URI.parse('http://jack:email@example.com/todo.cgi'),
I just don't know the parameter to use to POST the ICS data to that URL...anyone know?
