Hi,

We have recently been working on a cyrus murder setup including CalDAV and 
CardDAV.

For IMAP there are two possibilities to achieve high availability & load 
balancing:
* Use the proxing capability to get to the right backend
* Connect to a random backend and use IMAP Login referrals to find the correct 
backend.

For *DAV it seems proxying should be possible, but we quickly found at least 
two issues which seems to tell me nobody is using it this way:
* PUT requests are not proxied (I put in a pull request to fix this: 
https://github.com/cyrusimap/cyrus-imapd/pull/4302)
* autocreate does not work (is attempted on the proxy instead of the backend).

The alternative approach that somewhat mirrors what IMAP login referrals do 
would be to use the *DAV discovery mechanism essentially doing a 30x redirect 
to the correct backend,
but I don't suppose this is currently implemented?

I could work on either solution but was wondering whether somebody has solved a 
similar issue, or whether I'm overlooking something.

Cheers,
Christian
