Thanks for the response.
Just to confirm when you say "...but you can remove a rule and add another
in its place..." - can this be done at runtime - i.e server is running, i go
add a new rule/change the output of an existing rule. If so, can i have the
new rule take effect ?
Also, do i need to include any specific jar file for this dynamic feature ?
Am not looking at performance here - more from a maintenance/changeability
point of view.
