[2005] Issues with re-writing URLs and Global.asax

[Kasracer]

So I setup Global.asax to manage my URLs and it works great in my development environment (running on the Visual Studio server) but when I publish the site and place it under IIS (IIS 7; Vista) to test it, it doesn't seem to work at all.

Is there something I'm missing?

All of my URL re-writing is done in the Application_BeginRequest event using Context.RewritePath.

Small snippet:

List<string> Args = new List<string>(HttpContext.Current.Request.Path.Split('/'));
            Args.RemoveAll(EmptyString);
            if (Args.Count > 0)
            {
                switch (Args[0].ToUpper())
                {
                    case "ABOUT":
                        Context.RewritePath("/Pages/About.aspx");
                        break;
                 }
            }

Would it be better to convert to using an Http Handler?
