 * Hi Guys,
 * I’ve noticed that when i have two versions of the same theme (with different 
   URLs sharing the same memcached server that occasionally it appears that the 
   set and getting of objects is somehow getting mixed up between the two sites 
   resulting in gibberish.
 * Is there some way to add a unique prefix to the keys generated in W3TC so i can
   share the same memcached server between the two sites?
