title: How to do memcached sessions with django 1.8
body: <p>In my django 1.6 app I did the following to get cached sessions and I'm curious if any of this has changed for django 1.8. The goal here is 100% in memory sessions so a restart will wipe the slate clean / that each web request will require 1 less database query / that it could scale many frontend machines if I need to share this session across a load balancer (also assuming 1.8 still passes the CSRF token in the cookie ... this should work across a farm of servers)</p>
  
  <p>First I would add a requirement to the txt file like so</p>
  
  <pre><code>python-memcached==1.54
  </code></pre>
  
  <p>Next in my settings file I'd do the following</p>
  
  <pre><code>SESSION_ENGINE = "django.contrib.sessions.backends.cache"
  
  CACHES = {
      'default': {
          'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
          'LOCATION': '127.0.0.1:11211',
      },
  }
  
  CACHE_BACKEND = 'caching.backends.memcached://localhost:11211'
  </code></pre>
  
  <p>Has anything changed? Could I add anything to improve this based on the requirements I listed above?</p>
