+ * was later decided that since the recommended practice is to always 
+ * install local static routes through 127.0.0.1 for all your network
+ * interfaces, that we could solve this problem without a code change.

+ * The configuration file should always be used, since it is the only way
+ * to specify a default domain.  If you are running a server on your local

+ * in the configuration file.
