title: How to implement ServiceStack Redis Client with timeout
body: <p>We are implementing a pattern where our client checks to see if a document exists in Redis, and if it does not, we then fetch the data from the database.</p>
  
  <p>We are trying to handle a case where the Redis server is down or unreachable so we can then immediately fetch from the database.</p>
  
  <p>However, when we test our code by intentionally taking down the Redis server, the call to Redis via the ServiceStack client does not timeout for approximately 20 seconds.</p>
  
  <p>We tried using the RedisClient .SendTimeout property to various values (1000, 100, 1), but the timeout always happens after approx 20 seconds.  We also tried using the .Ping() method but have the same problem.</p>
  
  <p>Question: how can we handle the scenario where the Redis server is down and we want to switch to a DB fetch more quickly?</p>
