	   Many webservers will not cooperate well with Finder PUT requests,

	   The symptom of this problem is that Finder sends files to the
	   server, but they arrive as 0-length files in PHP.
	   If we don't do anything, the user might think they are uploading
	   files successfully, but they end up empty on the server. Instead,
	   we throw back an error if we detect this.
	   The reason Finder uses Chunked, is because it thinks the files
	   might change as it's being uploaded, and therefore the
	   Content-Length can vary.
	   Instead it sends the X-Expected-Entity-Length header with the size
	   of the file at the very start of the request. If this header is set,
	   but we don't get a request body we will fail the request to
