This approach will not necessarilly work in a cluster. The created Thread exists only in the initial server within the cluster (and only if security allows the creation of new threads). If due to failover or load balancing, request from the client are sent to a different server, this doesn't work. I've been looking to add real support for long-lived processes such as these into Tapestry ... but it requires sending a server push document, as a multipart response (which not all web browsers support).

  Both solve the same problem: overloaded servers
  that must handle heavy tasks. The cluster is the
  very expensive solution and the progress bar is
  the cheap one.
  
  You normally don't use a progress bar where a
  cluster is needed. You just add 100 servers and
  have fun managing them :-(
  
  And it doesn't make sense to invest in a cluster
  when a progress bar can do the job. You do
  something else with your money :-)
