title: Redis or Memcache with OpenCart
body: <p>We are using <code>OpenCart</code> version 2.x for our site and now as we are going to run marketing campaign we are expecting loads of traffic. Can someone tell me where can I define <code>Redis/Memcache</code> in <code>OpenCart</code> for session and cache storage manually just like we do for <code>Magento</code> in <code>local.xml</code> file.</p>
