title: Memcached CAS keys not being replicated properly on both the servers
body: <p>we are using two  Memcached servers clusterted (Master , Master  ) and used repcached on top of it for replication purpose ,  for our heavy traffic website </p>
  
  <p>For all logged in users , I am doing a atomic  Memcached cas Operation as shown below .</p>
  
  <pre><code>long casVal = resp.getCas();
  MemcacheClinet.cas(TOTAL_USERS, 0,value, casVal);
  </code></pre>
  
  <p>After doing some research using Memcache Stats Commands on both the servers  using get TOTAL_USERS , i found that this key has got a different value on each server and its not being replicated properly and its behaving abnormally </p>
  
  <p>Please let me know if is it possible to get this key "TOTAL_USERS" replicated properly on both the servers ??</p>
  
  <p>Or is there any other way where  i can manually append the Data to this String ??</p>
  
  <p>I am uisng XMemcached 1.4.5 version  with repcached 2.2 installed on to it .</p>
  
  <p>Please share your ideas .</p>
