異なる2級ドメイン名の下でSessionが共有する問題の解決

まずwebconfigの構成を見てみましょう
2つの状況に分けて、具体的な配置は以下の
web.configの構成は以下の通りである:IIS 6:

  <system.web>

    <sessionState mode="StateServer" stateConnectionString="tcpip=192.168.1.60:42424" timeout="30" />

    <httpModules>
      <add name="SessionSharedHttpModule" type="Myun.Web.SessionSharedHttpModule, Myun.Web" />
    </httpModules>

  </system.web>

 
IIS 7:管理パイプモードは集積パイプモードであり、そうでなければIIS 6と同じである
 

 <system.web>


    <sessionState mode="StateServer" stateConnectionString="tcpip=192.168.1.60:42424" timeout="30" />


  </system.web>


 <system.webServer>


    <modules>
      <add name="SessionSharedHttpModule" type="Myun.Web.SessionSharedHttpModule, Myun.Web" />
    </modules>


 </system.webServer>

コードは次のとおりです.cs
