Can you please quote the specific sentences from
http://greenbytes.de/tech/webdav/rfc2616.html#PUT touch upon this topic? I
read the entire section and didn't see any of it to conflict with what I'm
doing. I understand that the PATCH document alleges that there is a problem
with what I'm doing, but frankly he doesn't provide any proof of this. It's
not clear how using PUT for incomplete updates could cause problems for
proxies.
