mcrouter compatibility

[theosilva]

Hi,

Working with this bundle on its release 2.1, I had issue with mcrouter or any working cluster of memcache servers. I fixed this problem by a simple hack in Lsw\MemcacheBundle\Cache\LoggingMemcache at line 145 in get method :

$result = parent::get($_key);

This method has these two pointer parameters "&$flags=null" and "&$cas=null" which are may be usefull in set method but completely not used to get values. These two parameters won't allow to get value with any cluster or memache proxy.

Thanks for this project.

I disagree with them being "completely not used".

For more information about what CAS is and what the flags mean, read:
