using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Security;namespace aspnetajaxtast
{public class FormsAuthsessionModule : IHttpModule{public void Dispose(){}public void Init(HttpApplication context){context.PostAuthorizeRequest new EventHandler(context_PostAuthorizeRequest);}void context_PostAuthorizeRequest(object sender, EventArgs e){HttpApplication app sender as HttpApplication;HttpContext c app.Context;if (c.User.Identity.IsAuthenticated){FormsAuthenticationTicket ft (c.User.Identity as FormsIdentity).Ticket;Guid g;if (ft.UserData ! ){g new Guid(ft.UserData);}elseg Guid.Empty;MembershipUser user Membership.GetUser(c.User.Identity.Name);Guid currentSessionGuid;if (!string.IsNullOrEmpty(user.Comment)){string currentSessionStr user.Comment.Split(|.ToCharArray())[1];currentSessionGuid new Guid(currentSessionStr.Split(;.ToCharArray())[1]);}else{currentSessionGuid Guid.Empty;}if (g ! currentSessionGuid){FormsAuthentication.SignOut();//清空cookie登陆数据 需要重向url//自己自定义转到url的代码
}}}}
}web.config 需要配置httpmodule在system.web下httpModulesadd nameFormsAuthsessionModules typeaspnetajaxtast.FormsAuthsessionModule//httpModules这是vs测试或者iis7以下版本需要的如果在iis7 需要以下配置代码system.webServermodules runAllManagedModulesForAllRequeststrue add nameFormsAuthsessionModules typeFormsAuthsessionModule//modules/system.webServer测试需要两个浏览器就可以了 一个ie 一个ff可以当模拟两台电脑 如果你有两台电脑的话 也可以 转载于:https://www.cnblogs.com/wifi/articles/2456516.html
