You should initiate the HTTPWrapper before Request'ing, which initiates the Cookies and Proxy variables and will prevent our class from throwing an exception. HTTPWrapper.initHTTPWrapper;

Usage (GET):
HTTPWrapper.Request("www.neopets.com", "", "www.Referer.com");

Usage (POST):
HTTPWrapper.Request("www.neopets.com/login.phtml", "Username=Password=", "www.Referer.com");

Set a Proxy:
HTTPWrapper.strProxy = "127.0.0.1:80";
