SharePoint Session 值丢失

1.找到该站点的Config 文件，设置EnableSessionState=“True”，

<pages enableSessionState="true" enableViewState="true" enableViewStateMac="true" validateRequest="false" pageParserFilterType="Microsoft.SharePoint.ApplicationRuntime.SPPageParserFilter, Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" asyncTimeout="7">


2.取消 <add name="Session" type="System.Web.SessionState.SessionStateModule"/> 的注释
<httpModules>
      <clear />
      <add name="SPRequest" type="Microsoft.SharePoint.ApplicationRuntime.SPRequestModule, Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
      <add name="OutputCache" type="System.Web.Caching.OutputCacheModule" />
      <add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" />
