re: "Cross-Site Scripting" Jim Minatel's article as excerpted from chapter 18 of the book by Bilal Haidar ( Professional ASP.NET 3.5 Security, Membership, and Role Management)

I have question about a line of ASP code in this article:

Code:

 <% = Microsoft.Security.Application.AntiXss.HtmlEncode(this.txtName.Text) %> 

Where do you make references in the ASP code/app to the AntiXss DLL and what folder/directory location do you put the AntiXss DLL? And, what are the particulars for registering this DLL?
