Description

Performs a GET request for the root folder ('/') of a web server and displays the HTTP headers returned.

SYNTAX:

http.pipeline: If set, it represents the number of HTTP requests that'll be pipelined (ie, sent in a single request). This can be set low to make debugging easier, or it can be set high to test how a server reacts (its chosen max is ignored).

path: The path to request, such as '/index.php'. Default '/'.

http.useragent: The value of the User-Agent header field sent with requests. By default it is ''Mozilla/5.0 (compatible; Nmap Scripting Engine; http://nmap.org/book/nse.html)''. A value of the empty string disables sending the User-Agent header field.

http-max-cache-size: The maximum memory size (in bytes) of the cache.

useget: Set to force GET requests instead of HEAD.
