Log Level per appender for a single Logger

Question

Is it possible to configure different log levels for a single Logger based on the appender?

I realize this is similar to this question, and this is as far as I had already got myself, but the problem with this is that the threshold applies to all loggers that log to that appender, whereas I only want the threshold to apply to a single logger.

i.e. So far I have something like this:

log4j.rootLogger=WARN, stdout  log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.Threshold=WARN log4j.appender.stdout.layout=org.apache.log4j.SimpleLayout  log4j.logger.mylogger=DEBUG,logfile log4j.appender.logfile=org.apache.log4j.DailyRollingFileAppender log4j.appender.logfile.DatePattern=${roll.pattern.daily} log4j.appender.logfile.layout=org.apache.log4j.PatternLayout log4j.appender.logfile.layout.ConversionPattern=%d{${datestamp}} [%t] %-5p %C{2} - %m%n log4j.appender.logfile.File=mylogfile.log 

I want mylogger DEBUG messages to be send to the logfile appender, but I also want mylogger INFO messages to be sent to the stdout appender (but for all other loggers only WARN ings). Using the Threshold to limit stdout to WARN restricts the output of mylogger.

Aha, I fixed it by changing

log4j.appender.stdout.Threshold=WARN 

to

log4j.appender.stdout.Threshold=INFO 

Should have been more careful first time round.
