Generic way how to inject configuration from one module to another
Hi,
since people keep asking for that I'll ask here.
Is there a generic way how to modify configuration of some other
module from within f.e. mod-vhost-* modules? Somethink like per_dir
configuration?
I know it can be done, but you'll have to know the data structures and
link with header files of that module.
Use case:
1. Apache server using mod_vhost_ldap
2. Apache server using mod_php5
3. You want to be able to turn php_engine On/Off from the LDAP
mod_vhost_ldap would read the configuration from LDAP and inject
php_engine flag somewhere to vhost configuration in a generic way so
when mod_php5 is run it has the correct value of php_engine (the one
from LDAP).

Hi Guenter,
thanks for the patch. It's the example of how I don't want to do it
:-). I don't want to have code specific to the module I modify (zend_*
in your patch).

I did just check my source dir of your module, and found there a 4+
years old patch hanging around which I found somewhere but never tried ...
maybe that can point you into the right direction ...
Gün.
