ASP.NET URL Rewriting confusion
===

I have not previously done any URL rewriting in the past. When reading through <a href="http://msdn.microsoft.com/en-us/library/ms972974.aspx">THIS</a> article, I encountered a few problems in the author's ModuleRewriter class, located about halfway down the article. The code inside the ModuleReWriter refers to objects that I cannot find and have no idea how to create myself.  These are:<br /><br />
-RewriterRuleCollection<br />
-RewriterUtils<br />
-Regex

Did I mess something up or is it the author's fault?
