I'm not aware of such an option (doesn't mean it doesn't exist, though). |

The cleanest solution I can think of is to order apache to send its logs |
| 27 |
to syslog. [1] shows how to do this. Of course you still have to reload |
| 28 |
syslog-ng when you rotate the log files but apache itself can keep running. |
