The remote host contains a file named 'robots.txt' that is intended to
prevent web 'robots' from visiting certain directories in a web site for

use the contents of this file to learn of sensitive documents or
directories on the affected site and either retrieve them directly or
target them for other attacks.

server's access controls to limit access to sensitive material.
