  Please help me to solve this issue.</p>
  
  <p>Thanks in advance.</p>
  
  <p>I have implemented with below script:</p>
  
  <pre><code>    $frontendOptions = array(
              'lifetime' =&gt; 7200, // cache lifetime of 2 hours
              'automatic_serialization' =&gt; true
      );
  
      $backendOptions = array(
          'servers' =&gt;array(
              array(
                  'host' =&gt; 'localhost',
                  'port' =&gt; 11211
              )
          ),
          'compression' =&gt; false
    );
  
    // getting a Zend_Cache_Core object
    $cache = Zend_Cache::factory('Core',
          'Memcached',
          $frontendOptions,
          $backendOptions);
  
    Zend_Registry::set('mem_cached', $cache);
  </code></pre>
