In addition to questions that I have in below email, I have couple of question.
1. activation property disable - Does it first turn off new requests to that worker and then disable the worker after finishing old requests. So is this the best way to see 0 customer impact? 2. activation propery stopped - Does it throw away existing sessions and also stop taking new requests. Also I couldn't find way to see how mod_jk is behaving in the log file. I turned tracing on for JkLogLevel.
