Comment # 4 on bug 86335 from Sébastien Villemot

Thanks for making progress on the issue.

What I still don't get however is why a transfer of 26Mb is needed for a 300kb
ICS file. It should theoretically be possible to keep your existing check (i.e.
downloading the whole calendar) but using a more efficient download method. Is
it a limitation of the CalDAV protocol? A bug in radicale? I don't know the
underlying technical details, so I may miss something though…
