[CalendarServer-users] Can calendar server import file?

I have installed Darwin calendar server already. Now I want to import my ics files to my server but I can't find the way to do that. I try to copy my files to my user's directory but it's not work. But it seems the server can't find it so when I use iCal connect to my server it can't find my files. Does someone know any way to import files to the server? Tell me please. Thank you.
