Log4j: add parameter to log file name

Question

I have web application and I log some info on user requests. I need to include client ip address in a log file name, so I'd get separate log file for each ip. Can I define some file naming pattern with parameters (ip in my case)? I have string ip variable.

File name example: mylog-127.0.0.1.log

Thanks

Could I just suggest if you are going this way, from an ordering point of view, `mylog-127.000.000.001.log` instead as a naming convention? — David M, Jan 28 '13 at 13:58
@David M doesn't matter, it could be session ID or anything else, but thanks anyway — Timofei Davydik, Jan 28 '13 at 14:00

If you use client IP in naming the log files, the amounts of those log files will be huge, are you sure you want it like that ? — Gavin Xiong, Jan 29 '13 at 02:27

If you can switch to logback, I suggest you use SiftingAppender instead.
