      Description

      The change of the sticky-session-force attribute requires a httpd restart.
      Environment:
      Apache with mod_cluster and two JBoss AS7 (standalone mode but with ha configuration).
      Initial setting:

      1. sticky-session=true
      2. sticky-session-force=false

      Example output:

      27 28520f70
      Switch to node c178529b
      28 c178529b took 2 seconds
      29 c178529b

      The documentation for sticky-session-force says:

      Indicates whether the httpd proxy should return an error in the event that the balancer is unable to route a request to the node to which it is stuck. This property is ignored if stickySession is false.

      We change sticky-session-force to true. Now I expect an 503 error ...
      But nothing happens...

      5 28520f70
      Switch to node c178529b
      6 c178529b
      7 c178529b

      ... after a restart of httpd and JBoss the expected error happens:

      3 28520f70
      Failed to open "http://ci.objectbay.com:8000/demo7/". Error code - 503.
      Broken between 3 and 0 for 0 seconds.
      Failed to open "http://ci.objectbay.com:8000/demo7/". Error code - 503.
      Broken between 0 and 0 for 1 seconds.

      It seems that the change in the settings requires a complete restart of the cluster environment.
