Logging to troubleshoot WebDAV?

I'm having trouble connecting to my cubby.com via WebDAV (which works OK with other clients). 

I know WebDAV implementations have their vaguaries, and you're not going to be able to check compatibility with every server out there.

If WebDAV connections could be logged (perhaps via email, or to a folder accessible via the built-in WebDAV server), it might help to know who to follow up with (in this case, you or cubby.com).

Cheers.
