Hi

Is it possible to configure the SiftingAppender to use parameters from MDC other than the discriminator ?

I'd like to achive the following :

in java:

MDC.put("logger", loggerName);

MDC.put("file", fileName);

MDC.put("pattern", pattern);

in config:

<appender name="SIFT" class="ch.qos.logback.classic.sift.SiftingAppender">

<discriminator>

<Key>logger</Key>

<DefaultValue>default</DefaultValue>

</discriminator>

<sift>

<appender name="FILE-${logger}" class="ch.qos.logback.core.FileAppender">

<File>${file}</File>

<Append>true</Append>

<Encoding>UTF-8</Encoding>

<BufferedIO>true</BufferedIO>

<ImmediateFlush>true</ImmediateFlush>

<layout class="ch.qos.logback.classic.PatternLayout">

<Pattern>{pattern:-%d [%thread] %level %mdc %logger{35} - %msg%n}</Pattern>

</layout>

</appender>

</sift>

</appender>

Thanks
