[Evolution] Evolution and the X-NC-CalDAV-Webcal-Caching header

[Robin Lee <robinlee mailbox org>]

Hi

My setup is a Nextcloud (18.0.4) server and Evolution (3.36.2) running
on my desktop and laptop. The Evolution are CalDav clients to the NC. I
've set up a public holiday subscription calendar in NC and the problem
is that it doesn't show up in Evolution. I asked about this on NC forum

https://help.nextcloud.com/t/propagation-of-a-subscription-calendar/82539

and it seems that Evolution doesn't support the X-NC-CalDAV-Webcal-
Caching header. 

Is there a reason why it is not supported?

I could of course solve this by setting up the public holiday
subscriptions in Evolution on both my desktop and laptop, but I think
it would be more elegant to just have it in one place.

Cheers
Robin
