利用StateServer实现Session共享

1、更改web.config文件system.web中修改节点

注：tcpip=localhost:42424 tcpip的值可以设置为远程电脑的ip，如果设置为localhost说明session的值存放在本地服务器上面，如果设置为远程ip的话，则session存放在该远程服务器上。

在web.config文件system.web中添加节点

在web.config文件<[system.web][]>下添加节点

<httpCookies domain="test.com" />

2、打开session所在服务器的“服务”设置，将“aspnet\_state”服务开启，将其设置为自动启动模式

3、如果session所在的服务器不是本地服务器，需要在session所在服务器的注册器中将允许远程访问设置打开，HKEY\_LOCAL\_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\aspnet\_state \\Parameters 节点 → 将 AllowRemoteConnection 的键值设置成“1”（1 为允许远程电脑的连接，0 代表禁止）→ 设置 Port (端口号)

4、修改Global.asax代码实现Session共享

方法一：在Global.asax代码中修改Session\_Start()方法：

protected void Session_Start()
            {
                foreach (string moduleName in this.Modules)
                {
    				//需要在web.config中配置
    				//<add  key ="SessionKey" value="HrssSession" />
    				//一定要保持不同应用程序中的appName的值一致
                    string appName =ConfigurationManager.AppSettings["SessionKey"];
                    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);
                            }
                        }
                    }
                }
    
    
                if (Response.Cookies != null)
                {
                    for (int i = 0; i < Response.Cookies.Count; i++)
                    {
                        if (Response.Cookies[i].Name == "ASP.NET_SessionId")
                        {
                        	//ConfigurationManager.AppSettings["RootDomain"];
                            Response.Cookies[i].Domain = ".test.com";      //一定要保持不同应用程序的"ASP.NET_SessionId"的cookie的Domain值一致
                        }
                    }
                }
            }

方法二：网站的Global.asax.cs中加入下面代码

public override void Init()
            {
                base.Init();
                foreach (string moduleName in this.Modules)
                {
    				//需要在web.config中配置
    				//<add  key ="SessionKey" value="HrssSession" />
    				//一定要保持不同应用程序中的appName的值一致
                    string appName =ConfigurationManager.AppSettings["SessionKey"];
                    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);
                            }
                        }
                    }
                }
            }
