asp.net 多站点共享StateServer Session

1. <sessionState mode="StateServer" stateConnectionString="tcpip=127.0.0.1:42424" cookieless="false" ></sessionState>

2. 打开注册表,运行cmd/regedit,找到节点HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\aspnet_state\Parameters

   　　a.将AllowRemoteConnection值设置为1

   　　b.将Port值设置为a5b8(十六进制)，即十进制42424(默认值)

3. 分别在网站项目A和网站项目B的Global.asax.cs中加入下面代码

   public override void Init()
           {
               base.Init();
               foreach (string moduleName in this.Modules)
               {
                   string appName = "APPNAME";
                   IHttpModule module = this.Modules[moduleName];
                   SessionStateModule ssm = module as SessionStateModule;
                   if (ssm != null)
                   {
                       FieldInfo storeInfo = typeof(SessionStateModule).GetField("_store", BindingFlags.Instance | BindingFlags.NonPublic);
                       SessionStateStoreProviderBase store = (SessionStateStoreProviderBase)storeInfo.GetValue(ssm);
                       if (store == null)//In IIS7 Integrated mode, module.Init() is called later
                       {
                           FieldInfo runtimeInfo = typeof(HttpRuntime).GetField("_theRuntime", BindingFlags.Static | BindingFlags.NonPublic);
                           HttpRuntime theRuntime = (HttpRuntime)runtimeInfo.GetValue(null);
                           FieldInfo appNameInfo = typeof(HttpRuntime).GetField("_appDomainAppId", BindingFlags.Instance | BindingFlags.NonPublic);
                           appNameInfo.SetValue(theRuntime, appName);
                       }
                       else
                       {
                           Type storeType = store.GetType();
                           if (storeType.Name.Equals("OutOfProcSessionStateStore"))
                           {
                               FieldInfo uribaseInfo = storeType.GetField("s_uribase", BindingFlags.Static | BindingFlags.NonPublic);
                               uribaseInfo.SetValue(storeType, appName);
                           }
                       }
                   }
               }
           }
