This variable holds an instance of the database connection and can be used as required. The connection is itself an instance of a standard ADOdb connections, and all available functionality may be used.

The feature is also useful if you want session manager to use a connection that relies on complex connection parameters, such a MySQL SSL certificates (see the second example) which cannot be achieved using the normal session connection. This is done by telling the session manager to use an already instantiated connection.
