thanks,

Let me explain my project. I'm creating a new logger object each time a user enters the application, and redirect it to file like
"appname/username.log". The logger should be closed when the user sessions expires.

How can i close a Logger object? i only know how to remove the associated appenders...

Another problem is that the DailyRollingFileAppender never renames the file if the logger is no longer used.

It seems this is not the usual way to use Log4j... Has log4j been designed for this kind of usage?

Instead i would have a single Logger object, and a field in each line with the username, and use external program to parse the files, as Boris
suggested.
