[logback-user] NDC?

[Ceki Gulcu]

Hello Mark,

Logback offers an alternative to log4j NDC (nested diagnostic context) with a 
similar concept called MDC (mapped diagnostic context). See 
http://logback.qos.ch/manual/mdc.html for further details.

We dropped NDC in favor of MDC because the latter is easier to manage. With MDC 
you need to manage a map instead of a stack. By the way, log4j has both NDC and MDC.

HTH,
