> 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:
> # {{sticky-session=true}}
> # {{sticky-session-force=false}}
> Example output:
> {quote}
> 27 28520f70 
> Switch to node c178529b
> 28 c178529b took 2 seconds
> 29 c178529b 
> {quote}
> The documentation for {{sticky-session-force}} says:
> {quote}
> 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.
> {quote}
> We change {{sticky-session-force}} to {{true}}. Now I expect an 503 error ...
> But nothing happens...
> {quote}
> 5 28520f70 
> Switch to node c178529b
> 6 c178529b 
> 7 c178529b 
> {quote}
> ... after a restart of httpd and JBoss the expected error happens:
> {quote}
> 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.
