Re: [logback-user] Question about MDC in servlet init() method

Question was:

Can I set MDC variables in init() and read them in service() safely, or does this work only randomly or under special conditions?

I found the answer myself, because I managed to reproduce the problem :-) Obviously, MDC variables get lost when the application is idle for a while. So I am sure now that I have to set them again in the first lines of service() before I can read them. In service() I cannot safely use MDC variables that have been set in init(). Is that correct?
