If you need to force the user to a particular page, regardless of what the ReturnURL is stating, then use the following code in your Page_Load

        protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack && !string.IsNullOrEmpty(Request.QueryString["ReturnURL"]))
            {
                //Do this to remove any URL info the user may be trying to get to
                Response.Redirect(@"default.aspx");
            }

        }
