title: How to disable MemCached timeout in Werkzeug
body: <p>Is it possible to set the timeout for MemCached values to infinite (disable it) in Werkzeug?</p>
  
  <p>I tried the following: </p>
  
  <pre><code>    cache = MemcachedCache(['127.0.0.1:11211'], default_timeout=None)
  </code></pre>
  
  <p>This gives an error. If I do this:</p>
  
  <pre><code>    cache = MemcachedCache(['127.0.0.1:11211'], default_timeout=0)
  </code></pre>
  
  <p>It literally gives it a default_timeout of 0 seconds and nothing is stored. How can I set the default_timeout such that it gets disabled? </p>
