ra_serf in trunk, speaking HTTPv2 with the server, doesn't make use of the dav_cache. But I can see how that might be a problem when switching between serf and neon, because neon *does* consult the dav cache (which in your case, I'm guessing, must be stale).
At a minimum, if ra_serf isn't going to consult the dav cache, it should at least be sure to invalidate whatever is stored therein so as not to trip up neon.
