应用redis出现如下错误
It was not possible to connect to the redis server(s); to create a disconnected multiplexer, disable AbortOnConnectFail. SocketFailure on PING
参考stack overflow上文章 http://stackoverflow.com/questions/30895507/it-was-not-possible-to-connect-to-the-redis-servers-to-create-a-disconnected
是因为在StackExchange.Redis会默认 abortconnect=true,即当redis连接报错（如服务器上停止redis service等）时StackExchange会自动停止，即便后来redis服务端修好能够接通时，也不会自动连接。
所以需要在连接字符串里将值设置为false。若在webconfig中写成 <RedisCaching Enabled="false" ConnectionString="88.110.22.88,abortConnect=false" />
The error you are getting is usually a sign that you have not set abortConnect=false in your connection string. The default value for abortConnect is true, which makes it so thatStackExchange.Redis won't reconnect to the server automatically under some conditions. We strongly recommend that you set abortConnect=false in your connection string so that SE.Redis will auto-reconnect in the background if a network blip occurs.
