This code shows you how ASP.NET simplifies information about the current browser into class properites. There are others but these are the most useful.

<%@ Page Language="c#" %>
<script runat="server">

   public void Page_Load(Object sender, EventArgs e) {
     HttpBrowserCapabilities bc = Request.Browser;
     Response.Write("Name = " + bc.Browser + "<br>");
     Response.Write("Version = " + bc.Version + "<br>");
     Response.Write("Platform = " + bc.Platform + "<br>");
     Response.Write("Is Crawler = " + bc.Crawler + "<br>");
     Response.Write("Is AOL = " + bc.AOL + "<br>");
   }

</script>
