title: Django cache how to remove key prefix of ":1:"
body: <p>I set a cache in Django as below:</p>
  
  <pre><code>from django.core.cache import cache
  ...
  cache.set("cae9ad31b9206a1b5594813b509e1003", "test", timeout=10)
  </code></pre>
  
  <p>It generates a key like this:</p>
  
  <pre><code>:1:cae9ad31b9206a1b5594813b509e1003
  </code></pre>
  
  <p>How to remove <code>:1:</code> prefix from the key?</p>
