Please add caldav support over https for orage. In times of aviability of mobile internet this seems to become a show stopper. Thanks for this great calendar!
Maybe libical could be used to implement this: http://libical.github.io/libical/
Orage is already using libical, so that does not help. But yes, I agree that it would be great to have network support. It just is not that easy....
What about http://libcaldav.sourceforge.net/ then?
Integrating the configuration of vdirsyncer into Orage may make this easier - I'm using vdirsyncer for all of my calendars in Orage and it works well.
The orage project is not maintained anymore and has been archived. Closing bugs.
