[logback-user] Nested sifting appenders

Hi Ceki,

I created a new discriminator taking the code of MCDBasedDiscriminator
and modifying the method getDiscriminatingValue(ILoggingEvent event)
as follows.

public String getDiscriminatingValue(ILoggingEvent event) {
        Map<String, String> mdcMap = event.getMDCPropertyMap();

        // If the MDC is empty return the default path
        if (mdcMap.isEmpty()) {
            return defaultValue;
        }

        String parentValue = mdcMap.get("parent");
        String nodeValue = mdcMap.get("node");

        return parentValue + "/" + nodeValue;
}


Cheers,
Dario
