 * Hi there,
 * only a few lines are “live” in db-config.php. Three towards the top of the file,
   and two blocks underneath the heading
 * /** Sample Configuration 1: Using the Default Server **/
    /** NOTE: THIS IS ACTIVE
   BY DEFAULT. COMMENT IT OUT. **/
 * What the guys have done here is give you a “sample configuration” which uses 
   the values from your wp-config.php file. Hence by just installing the plugin 
   it would be switched on, but you wouldn’t notice any differences (since only 
   one database server is active for reads and writes).
 * Now you copy the second block and add the values for your second database server–
   that’s how you configure it. This will work on shared hosting, but it only makes
   sense if you have more than one database server so you’d configure one for reading
   and one for writing (or reading and writing).
 * Please note that HyperDB DOES NOT replicate your database or user accounts! You
   need to do this yourself. You can refer to this article from the MySQL manual:
 * [http://dev.mysql.com/doc/refman/5.1/en/replication-howto.html](http://dev.mysql.com/doc/refman/5.1/en/replication-howto.html)

 * Does this “get along” with WP Super Cache?
