For SEO purposes, you may want to redirect all requests to WWW. The following codes use the Global.asax Application_BeginRequest() to capture the request and redirect.

protected void Application_BeginRequest() { //redirect to www string url = HttpContext.Current.Request.Url.ToString(); bool redirectToWWW = false; //dont redirect to www on localhost //could also set up a appsetting to control when to force redirect redirectToWWW = !url.Contains("localhost"); if (redirectToWWW) { string scheme = HttpContext.Current.Request.Url.Scheme; if (!url.StartsWith(scheme + "://www.")) { string newUrl = url.Replace(scheme + "://", scheme + "://www."); Response.Redirect(newUrl); } } }
