Raj, 
This servlet compliments configureAndWatch by providing an alternate way to adjust 
logging levels while the application is running. I think that your guess about how 
this servlet will behave in a cluster is accurate. JMX is probably a more direct way 
to control logging levels throughout a cluster, although I don't know if anyone has 
implemented that functionality yet.
