[syslog-ng] Send Apache log to a separate loghost

In version 1.6.11 of syslog-ng, I need to send Apache logs to a different loghost than the rest of the system logs. Is that possible? If so, how? Our syslog-ng was set up quite some time ago by an admin who is no longer around. I've spent more time than I can afford trying to decipher and attempt to modify his syslog-ng.conf. Assistance from some experts would be greatly appreciated. Thanks, Lee
