How to get the URL basename and IP address of current serlet context?

For example, if my website is "www.non-existent.website.com", and Tomcat is running on this website, then how can I get the website name? Preferrably I'd like to get it from the ServletContextEvent. What I want to do is this:

class MyListener implements ServletContextListener {
   public void contextInitialized(ServletContextEvent sce) {
      if (sce.getServletContext().getDomain().equals("www.non-existent.website.com"))
         setLoggerLevel(Level.WARN);
      else
         setLoggerLevel(Level.DEBUG);
   }
}

So when running the app server on a debug machine, I want to set the log level to DEBUG, otherwise to WARN. The DEBUG machine has the URL basename as "localhost".

Getting the IP address is a related question. But on a complex load balanced system, the IP address could change with each request.

Thanks.
