title: How to set a string with TTL with StackExchange.Redis
body: <p>I'm looking for a way to do a very <a href="http://redis.io/commands/setex" rel="nofollow noreferrer">simple TTL</a> string in Redis:</p>
  
  <p>So how do I do the equivalent of the following in <em>StackExchange.Redis</em>?</p>
  
  <pre><code>SETEX lolcat 10 "monorailcat"
  </code></pre>
  
  <p>I found <code>KeyExpire</code>, but that means every key I set needs two calls?</p>
