[logback-user] Context selectors useful?

[Mense, Holger]

Hello Ceki, 

[Usage of context selector in multi threaded environments]

Yes, currently my context selector relies on MDC. I think your 
suggested MultiAppender would also solve my problem for now. However
with the context selector I am currently more flexible on deciding
at one central point, to which LoggerContext I need to pass a log event.

Furthermore it is currently possible for me to distinguish different
logback configuration files for different thread classes. This allows a
far more fine-grained configuration.

Okay. That's good :)
