title: Django Multiple Caches - How to choose which cache the session goes in?
body: <p>I have a Django app set up to use multiple caches (I hope).  Is there a way to set the session to use a specific cache, or is it stuck on 'default'?</p>
  
  <p>Here's what i have now:</p>
  
  <pre><code>CACHES = {
      'default': {
          'BACKEND': 'util.backends.SmartMemcachedCache',
          'LOCATION': '127.0.0.1:11211',
          'TIMEOUT': 300,
          'ANONYMOUS_ONLY': True
      },
      'some_other_cache': {
          'BACKEND': 'util.backends.SmartMemcachedCache',
          'LOCATION': '127.0.0.1:11211',
          'TIMEOUT': 300,
          'ANONYMOUS_ONLY': True,
          'PREFIX': 'something'
      },
  
  }
  
  SESSION_ENGINE = 'django.contrib.sessions.backends.cached_db'
  </code></pre>
