Module initialization
I must just be dense, but I've spent a whole bunch of time trying to
figure exactly how I can put initialization code into my module. It's
code that needs to run only once when apache (2.2.x) is starting up,
so any pointers would be appreciated.
Thanks!

Is preconfig code run only once, not being run again even on a restart?

ap_hook_pre_config(your_routine, NULL, NULL, APR_HOOK_MIDDLE)
static int your_routine(apr_pool_t * p_conf, apr_pool_t * p_log,
apr_pool_t * p_temp);

Any impact if put in ap_hook_post_config() ?

Go have a read of:
http://www.fmc-modeling.org/category/projects/apache/amp/Apache_Modeling_Project.html
It goes into quite a lot of details of how the internals of Apache
works. It includes lots of pretty pictures of how all the phases and
hooking functions for this sort of thing relate to each other and when
they are triggered.

OK, thanks for that tidbit. However, as someone else mentioned, if I
need to do something when apache is restarted, will this do the trick?
Also, when apache is shutting down, can my module do clean up and how
do I handle that?
Thanks!
