Hi,
Is there any decent way of determining from inside a module, what mpm
is being used ? I have to share some memory between requests, which
needs a shared mem segment if we're using processes/kids but I can get
away with regular mem if it thread-based or some other single-process
mpm. Don't want to waste a shared-mem segment if I don't have to.
Thanks,
Greg.
