title: Django: Should I use LocMemCache caching?
body: <p>I am using this <a href="https://github.com/dprog-philippe-docourt/django-qr-code#qr_url_from_text" rel="nofollow noreferrer">QR code generator</a>. There is a specific part in the documentation about caching. I read that <code>LocMemCache</code> should not be used in production. Is that also the case for these QR codes? Is there a caching that you can recommend instead, or is that approach fine at the beginning with a smaller page?</p>
  
  <pre><code>CACHES = {
      'default': {
          'BACKEND': 'django.core.cache.backends.locmem.LocMemCache',
      },
      'qr-code': {
          'BACKEND': 'django.core.cache.backends.locmem.LocMemCache',
          'LOCATION': 'qr-code-cache',
          'TIMEOUT': 3600
      }
  }
  
  QR_CODE_CACHE_ALIAS = 'qr-code'
  </code></pre>
