Asp.net Cookie保存上一个页面的URL地址

在详情页面判断如果未登录加入： Response.Cookies["RemainUrl"].Value = Request.Url.ToString();  保存当前页面的url地址

然后跳转到 登录页面

在登录页面登录成功后 判断 Cookie是否存在

HttpCookie cookie = HttpContext.Current.Request.Cookies["RemainUrl"];

  if (cookie == null)
                     {
                         this.ClientScript.RegisterClientScriptBlock(this.GetType(), "", "<script>location.href='memberCenter.aspx';</script>");
                     }
                     else
                     {
                         this.ClientScript.RegisterClientScriptBlock(this.GetType(), "", "<script>location.href='" + cookie.Value+ "';</script>");
                     }

这样就可以跳转到用户上一次访问的页面了。
