与会话状态服务器共享会话

Question

我正在尝试在 varnish round robin 负载平衡器之间设置两个 Windowz 框（win1、win2）。

应用程序的会话状态均配置为 "State server" 指向第三台计算机 (x.y.w.z)。 win1 和 win2 都可以调用 telnet x.y.w.z 42424。 Al 机器具有相同的 OS 版本。两台机器都有相同的机器密钥

我已经放入了从 http://pardini.net/blog/2011/02/17/the-ultimate-asp-net-session-state-debugging-tool/ 复制的 ans aspx 调试页面，它显示了两个不同的机器密钥。

我可以看出AppDomainAppId不一样；我该如何改变它？这里发生了什么？

按照 Sharing session state over multiple ASP.NET applications with ASP.NET state server 中的建议，我在 Global.aspx.cs

中添加了一个挂钩

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using NHibernate;
using NHibernate.Cfg;
using NHibernate.Context;
using NHibernate.Mapping.Attributes;
using System.Web.SessionState;
using System.Reflection;

/// <summary>
/// Summary description for Global
/// </summary>
public class Global : System.Web.HttpApplication
{
  public static ISessionFactory SessionFactory;

private static Configuration _configuration;

public override void Init()
{
    base.Init();
    foreach (string moduleName in this.Modules)
    {
        string appName = "MYAPPNAME";
        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);
                }
            }
        }
    }
}
