Question

我们不希望为此使用缓存集群，因为截至目前，我们在缓存集群上面临一些稳定性问题，因此它们处于持续维护状态（完全是我们的错）。我们可以使用专用集群进行会话存储吗？（忘记群集，至少有一个主机？）

在同一个应用程序中使用两个集群，一个用于缓存，一个用于会话存储，这些集群位于同一个配置文件中。

我的做法是对的吗？任何帮助，将不胜感激。谢谢！

感谢@CyberMax，我能够设置这个环境。但是，当我运行页面时，我得到一个错误：

无法读取配置节'dataCacheClients'，因为它缺少节声明

500 internal server error

这是我的配置：

<configuration>
  <configSections>
<!-- required to read the <dataCacheClient> element -->

编辑：

将dataCacheClient更改为dataCacheClients会导致此错误：

是的，你可以。

配置AppFabric Sesison State Provider时，您可以提供dataCacheClient名称。它是dataCacheClients配置部分中使用的dataCacheClient部分的名称。默认情况下，提供程序将使用名为“default”的dataCacheClient部分。

，例如

<sessionState mode="Custom" customProvider="AppFabricCacheSessionStoreProvider" compressionEnabled="false">
      <providers>
        <add name="AppFabricCacheSessionStoreProvider"
             type="Microsoft.Web.DistributedCache.DistributedCacheSessionStateStoreProvider, Microsoft.Web.DistributedCache"
             cacheName="default"
             useBlobMode="true"
             dataCacheClientName="dataCacheClient1"/>
      </providers>
    </sessionState>

您可以在configuraiton文件中拥有多个dataCacheClient。

 <dataCacheClients>
    <dataCacheClient name="dataCacheClient1">
      <hosts>
        <host name="CacheServer1" cachePort="22233" />
      </hosts>
    </dataCacheClient>
    <dataCacheClient name="dataCacheClient2">
      <hosts>
        <host name="CacheServer1" cachePort="22233" />
      </hosts>
    </dataCacheClient>
  </dataCacheClients>

因此，拥有多个缓存集群没有问题。

修改：

这里是AppFabric 1.0的配置

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

  <!--configSections must be the FIRST element -->
  <configSections>
     <!-- required to read the <dataCacheClient> element -->
     <section name="dataCacheClient"
         type="Microsoft.ApplicationServer.Caching.DataCacheClientSection,
            Microsoft.ApplicationServer.Caching.Core, Version=1.0.0.0, 
            Culture=neutral, PublicKeyToken=31bf3856ad364e35"
         allowLocation="true"
         allowDefinition="Everywhere"/>
  </configSections>

  <!-- cache client -->
  <dataCacheClient>    
    <!-- cache host(s) -->
    <hosts>
      <host
         name="CacheServer1"
         cachePort="22233"/>
    </hosts>
  </dataCacheClient>

  <system.web>
    <sessionState mode="Custom" customProvider="AppFabricCacheSessionStoreProvider">
      <providers>
        <!-- specify the named cache for session data -->
        <add 
          name="AppFabricCacheSessionStoreProvider" 
          type="Microsoft.ApplicationServer.Caching.DataCacheSessionStoreProvider" 
          cacheName="NamedCache1"
          sharedId="SharedApp"/>
      </providers>
    </sessionState>
  </system.web>
</configuration>

这里是AppFabric 1.1的配置

<?xml version="1.0"?>

<configuration>
  <configSections>
    <section name="dataCacheClients"
             type="Microsoft.ApplicationServer.Caching.DataCacheClientsSection, Microsoft.ApplicationServer.Caching.Core"
             allowLocation="true" allowDefinition="Everywhere"/>
  </configSections>

  <dataCacheClients>
    <dataCacheClient name="default" channelOpenTimeout="10000">
      <hosts>
        <host name="CacheServer1" cachePort="22233" />
      </hosts>
    </dataCacheClient>
  </dataCacheClients>

  <system.web>
    <sessionState mode="Custom" customProvider="AppFabricCacheSessionStoreProvider" compressionEnabled="false">
      <providers>
        <add name="AppFabricCacheSessionStoreProvider"
             type="Microsoft.Web.DistributedCache.DistributedCacheSessionStateStoreProvider, Microsoft.Web.DistributedCache"
             cacheName="default"
             useBlobMode="true"
             dataCacheClientName="default"/>
      </providers>
    </sessionState>
  </system.web>
</configuration>

我可以使用专用（单独）群集进行appfabric会话存储吗？
