description = [[
Checks if the target http server has mod_negotiation enabled. This
feature can be leveraged to find hidden resources and spider a web
site using fewer requests.
The script works by sending requests for resources like index and home
without specifying the extension. If mod_negotiate is enabled (default
Apache configuration), the target would reply with content-location header
containing target resource (such as index.html) and vary header containing
"negotiate" depending on the configuration.
