public void Init(HttpApplication context) { context.BeginRequest += new EventHandler(Application_BeginRequest); } private void Application_BeginRequest(object source EventArgs e) { HttpContext context = ((HttpApplication)source).Context; string ipAddress = context.Request.UserHostAddress; if (!IsValidIpAddress(ipAddress)) { context.Response.StatusCode = 403; // (Forbidden) } } private bool IsValidIpAddress(string ipAddress) { return (ipAddress == 127.0.0.1); } Hope the above code is bit clear and useful.
