[logback-user] Setting MDCFilter values at runtime

[ceki]

Hello Dan,

TurboFilters are added to the logger context. You can get hold of any 
installed tubo filter by searching in the list returned by 
LoggerContext.getTurboFilterList(). Once you have the turbo filter 
instance, you could reconfigure it as desired and invoke its start() 
method. You are done.

HTH,
