Log Rotation settings for ARPortal

Gurus,

How do you configure log rotation in ARPortal? In the WebDesigner.ConfigFileEditor.exe, I see the way to change the log file location. But, what is the way to configure log rotation settings (size, number etc).

We are seeing several files in the ARPortal\App_data\Logs directory of size 14KB. We would like to let the file fill up 10MB upto 10 files. How do we achieve that?

Thanks in advance.
