// ******** DATASTORE PREFIX ******
// If you are using a PHP Caching system (APC, XCache, eAccelerator) with more
// than one set of forums installed on your host, you *may* need to use a prefix
// so that they do not try to use the same variable within the cache.
// This works in a similar manner to the database table prefix.

// It is also necessary to specify the hostname or IP address and the port the server is listening on
