KohanaPHP » Kohana v2.x

There are 2 extensions provides an interface to memcached:

• http://ua2.php.net/manual/en/book.memcache.php
• http://ua2.php.net/manual/en/book.memcached.php

Using memcached, we get the opportunity to work with multiple servers.
So, the following code does not make sense (Memcache-based Cache driver):

        $servers = Kohana::config('cache_memcache.servers');

        foreach ($servers as $server)
        {
            // Make sure all required keys are set
            $server += array('host' => '127.0.0.1', 'port' => 11211, 'persistent' => FALSE);

            // Add the server to the pool
            $this->backend->addServer($server['host'], $server['port'], (bool) $server['persistent'])
                or Kohana::log('error', 'Cache: Connection failed: '.$server['host']);
        }

And added property "prefix. This is done to ensure that common names do not overlap at different sites
