using common hostnames.

Each HEAD request provides a different 'Host' header. The hostnames come from a built-in
default list. Shows the names that return a document. Also shows the location of redirections.

The domain can be given as the 'http-vhosts.domain' argument or deduced from the target's
name. For example when scanning www.example.com, various names of the form <name>.example.com are
tried.


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).


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.");
