Demonstrates subclassing the server to create a custom site. This site is an attacker -- a puppetmaster -- which serves HTML pages containing attack code. In this case, we are simulating JavaScript attack code which prompts the unsuspecting browser to request a number of images from a victim site. Delays are specified to simulate hiding the attack from the browser user by use of JavaScript timeouts or similar mechanisms. The generateBody virtual function is redefined to create a page containing the attack code.

This module definition has two additional parameters to the standard HttpServerDirect definition: * minBadRequests specifies the lower bound on bad requests caused to be sent to the victim by the browser. * maxBadRequests specifies the upper bound on bad requests caused to be sent to the victim by the browser.

Parameters

Name	Type	Default value	Description
hostName	string		The domain name of the server
port	int		The listening port number
httpProtocol	int		The http protocol: 10 for http/1.0, 11 for http/1.1. Not used at the present time.

siteDefinition	string		The site script file. Blank to disable.
config	xml		The XML configuration file for random sites
activationTime	double		The initial activation delay. Zero to disable.
minBadRequests	int		The lower bound of bad requests.
