Since the official documentation for log4j is a broken link, and the getting started guide isn't helping me, I would like to know how to use two appenders with different log levels for the same logger, using a .properties file instead of an .xml one.
For example, like this:
log4j.rootLogger=debug, APPENDER_FILE, APPENDER_STDOUT
I'm logging with two different appenders, but on the same log level (DEBUG). I would like to use an INFO log level for APPENDER_STDOUT, and aDEBUG log level for APPENDER_FILE.
My question is similar to this, but unlike that question, I'm using the log4j.properties file, not the xml file.

You need to set the logger to the more detailed of the two levels (DEBUG) but then set a threshold on the appender to tell it to only show messages at INFO and above
