+ This controls whether a node's web server should provide "ambient"
+ upload/create authority by controlling whether it responds to PUT and
+ POST requests that do not contain a cap -- i.e. those for uploading
+ new unlinked files and creating new unlinked directories. If set to
+ True, a node will respond to these requests as usual.  If set to
+ False, a node will instead refuse these requests, returning an HTTP
+ status of 'Bad Request'.  The default value is True.
+
+ Note that setting this to False does not prevent performing operations
+ on files and directories that already exist, since all of these operations
+ require the presentation of a cap.
