[OT] Apache on Windows, how many processes?
I know in the *nix world that Apache forks different processes and in
Windows it is threaded. I was load testing my Windows Apache Module with 50
clients and it never started up a second process, though the thread count
did surpass the 50, it went to 53. I am assuming the other three threads
where maintenance threads that are not counted in the thread pool.
My question is: Will Apache on Windows start up more then one worker
process? If so, what does it take to get that to happen?

No, it's certainly not legacy. It's very easy to have a semistable or
unstable httpd process once you add in your efforts to hack custom perl
or c modules, etc. The parent ensures that the server stays up, even
as a worker process is lost or gracefully quits for MaxRequestsPerChild.

Eric,
Interesting, so what purpose does the parent process preform with MPM
winnt? Is it just legacy?
