Description

Gets the date from HTTP-like services. Also prints how much the date differs from local time. Local time is the time the HTTP request was sent, so the difference includes at least the duration of one RTT.

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.
