Notice the conversion pattern ends with "%m" instead of "%m%n". This
is because when the message goes through the servlet context logging
mechanism, the latter adds the newline, so adding it to the conversion
pattern above would result in 2 newlines, which is why we leave it out.
Ok. So if I understand this correctly, your approach uses a servlet
listener to register all contexts keyed by the last part of their
context path, and you tell the appender in question which ServletContext
to retrieve and then forward to that logger.
Will this also work with multiple web apps using slf4j, or will they go
to the same appender?
