White pages configuration

[Todd Wright]

The primary tuning parameters are:
   -Dorg.cougaar.core.wp.server.successTTD
   -Dorg.cougaar.core.wp.server.failTTD
   -Dorg.cougaar.core.wp.server.expireTTD
   -Dorg.cougaar.core.wp.server.forwardPeriod
   -Dorg.cougaar.core.wp.resolver.transport.nagleMillis
These options control how often to renew cache and lease entries in the 
WP server.  Here's a paper I wrote on how the "TTD" settings affect the 
amount of WP traffic:

You can run with multiple, fully-replicated WP servers.  I've attached 
an HTML file that describes how to setup multiple servers.  As a very 
general guideline, try (say) one WP server for every 6 hosts.
