[Owncloud] CalDAV interoperability

[Evert Pot]

Hi!

Very odd that your patch actually fixed it. makes me wonder what the playbook request was. Does it send a request with no range at all?
I'd absolutely love to have a look at what the playbook is sending to the server. 

If it's possible at all, could you setup Charles HTTP Proxy as a reverse proxy between your owncloud server and the playbook?
This should allow you to easily record the entire conversation.

With that information I may well be able to patch SabreDAV.

I've heard of issues with the playbook before, but unfortunately I have not been able to get my hands on a device or a capture.

Cheers,
Evert
