  15.  * A simple Handler which logs the client certificate, request and response messages on INFO level
  16.  *
  17.  * To use this, deploy it in response flows (global, service, or transport).
  18.  * If is deployed in both response and request flows the elapsed time will be logged in milliseconds.
  19.  *
  20.  * Example for service use: <br/>
  21.  * <handler name="myHandler" type="java:org.apache.axis.handlers.MyHandler" /> <br/>
  22.  * <service name="..." provider="java:RPC"> <br/>
