The server can be configured to disallow operations involving what it considers to be illegal pathnames. A pathname is considered illegal if it contains non-printing characters, begins or ends in spaces, or begin with a period. For anonymous users, this feature is controlled by a-pathname-filter; for non-anonymous users, it is controlled by u-pathname-filter.
