Basically, we wanted to be able to use a simple Reverse Proxy (not Varnish, not Squid), that used a Memcache installation, instead of the file system.

I wrote a new MemcachedStore class that AppCache now uses instead. The biggest downside is, the configs for the servers aren't used by the AppCache piece.

Heres the MemcachedStore class. Right now, it's set up to use my AequasiMemcachedBundle Symfony bundle at the moment, but it wouldn't be that hard to change to just using Memcached or Memcache.

Then, in app/AppCache.php, do the following:

Require the MemcachedStore class at the top

#LANG:php
<?php 

require_once __DIR__ . '/AppKernel.php';
require_once __DIR__ . '/MemcachedStore.php';

class AppCache
{
	// ...

#LANG:php
<?php
//...
class AppCache
{
    // ...
    public function createStore()
    {
        $servers = [
            [ 'localhost', 11211 ]
        ];
    
        return new MemcachedStore( [
            'enabled'      => true,
            'debug'        => true,
            'persistentId' => serialize( $servers )
        ], $servers );
    }
    // ...
}

If you want to create a service to get to this particular store, you would have to create a $cache variable in your app/AppKernel, and overwrite your app/AppCache's handle() method to set the kernel's $cache variable before calling parent::handle.
