我一直在使用Enyim Memcached Client for .Net，试图连接到在AppHarbor上运行的服务器。我的配置文件的相关部分如下所示：

  <enyim.com>
    <log factory="Enyim.Caching.DiagnosticsLogFactory, Enyim.Caching" />
    <memcached protocol="Binary">
      <servers>
        <add address="8d593f28-37d7-4c4f-a702-aa7687a85ea1.memcacher.com" port="11211" />
      </servers>
      <authentication
          type="Enyim.Caching.Memcached.PlainTextAuthenticator, Enyim.Caching"
          userName="changed to post on stack overflow"
          password="changed to post on stack overflow"
          zone="AUTHZ"
              />
      </memcached>
    </enyim.com>

我的连接一直超时。有什么想法吗？以下是来自 Enyim 客户端的日志：

更新：

原来我无法连接到 memcached 服务器的原因是因为它只能从 appharbor 的环境中访问。因此，对于遇到此问题的其他任何人，您需要在本地开发时使用本地 memcached 服务，然后在部署时简单地更改凭据（apphaorbor 实际上会自动为您执行）。问题已解决。

AppHarbor Memcacher 存储桶只能从 AppHarbor 应用程序服务器访问。文档已被修改以清楚地反映这一点。

您应该使用本地安装的 memcached 服务器进行测试。
