a-pathname-filter
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, 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.
Examples:
a-pathname-filter=yes
a-pathname-filter=no
