title: mod_jk vs mod_cluster
body: <p>Can someone please tell me the pro's and con's of mod_jk vs mod_cluster.</p>
  
  <p>We are looking to do very simple load balancing..  We are going to be using sticky sessions and just need something to route new requests to a new server if one server goes down.  I feel that mod_jk does this and does a good job so why do I need mod_cluster?</p>
