W3TC memcached and sock

Hi all,

I am trying to use W3TC with memcached, but with socket support. I edited the

/wp-content/plugins/w3-total-cache/lib/W3/Cache/Memchaced.php

and replaced

$this->_memcache->addServer(trim($ip), (integer) trim($port), $persistant);

with

$ip = trim($ip);
                $port = (integer) trim($port);
                if( $ip[0] === '/' ) {
                    $port = 0;
                    $ip = 'unix://' . $ip;
                }
                $this->_memcache->addServer($ip, $port, $persistant);

And I have the memcached server up.

This used to do the trick in the older version, but now, when I test it, I get a Test Failed

Any help would be appreciated
