Thanks Jan.

I am looking for something similar to
http://code.hootsuite.com/logging-contextual-info-in-an-asynchronous-scala-application/
, I could able to find that either by using custom akka dispatcher or
custom execution context, we can achieve the same, but I would prefer
anything I can do with minimal changes in akka default behaviour.

Using MDC with Logback; the logback uses a ThreadLocal variable and this
works when one thread is used for one request, in case of Akka asynchronous
communication happens across multiple threads.

Thanks
Arun
