  +             So when running a cluster, only make sure that you have webapps in there
  +             that need to be clustered and remove the other ones.
  +             A cluster has the following parameters:

heartbeat

optimal would be the same amount of threads as nodes

on this host, 
  +                                in case of multiple ethernet cards.
  +                                auto means that address becomes

  +
  +            The filter attribute is to filter out requests that could not modify the session,
  +            hence we don't replicate the session after the end of this request.
  +            The filter is negative, ie, anything you put in the filter, you mean to filter
out,
  +            ie, no replication will be done on requests that match one of the filters.
  +            The filter attribute is delimited by ;, so you can't escape out ; even if you
wanted to.
  +
  +            filter=".*\.gif;.*\.js;" means that we will not replicate the session after
requests with the URI
