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.
|
|
