This example uses ASP.NET, you will need the MS .NET framework.
Locally viewing http://localhost/frames.aspx will show the framed content1.aspx. If you view http://localhost/content1.aspx it will automatically frame itself. You can substitute content1.aspx for any page as long as it has the include statement.
