It isn't really WebDAV, but more about HTTP, and it being a stateless protocol. Any given request could hit one of a (large) number of backends. Any caching that you might want to try goes right out the window (any state you hold can be changed by N other backends). This also means that buffering writes is very difficult, too. Batching operations into a single HTTP request could be very helpful. Jon suggested that a commit becomes one large POST with all of the metadata, and then N parallel PUTs with content. Thus, the hard work can be batched to one backend server, and sucking up the content can be parallelized across the server farm. Cheers, -g
