I'm not sure if the WebDAV protocol supports these ideas.
I've only been developing CardDAV stuff, which is based on WebDAV, but 
so far I haven't seen a way for "asynchronous" processing.

Also, you can't send "dots" because you have to send the HTTP status 
first, which can only be determined at the end of the operation.
