[users@httpd] VirtualHosts on mysql, now I need to support a certain directive

[Moreno Gentili <br...@tiscali.it>]

Hi everybody,
I'm trying to bridge the gap between two apache modules.

  * *mod_vhost_dbi* from outoforder.cc, which allows me to store virtual
    hosts on a mysql database.
  * *apache2-mpm-itk* which allows the assignment of a different
    user/group to each virtualhost.

The problem is that /apache2-mpm-itk/ requires a /AssignUserID/ 
directive in each VirtualHost but /mod_vhost_dbi/ doesn't support custom 
configuration directives.
I'm looking at /mod_vhost_dbi/ source code 
<http://www.outoforder.cc/projects/httpd/mod_vhost_dbi/> to see if I can 
modify it to supply a value for /AssignUserID/ but I'm starting to feel 
really lost.
I tried adding the key-value pair to the /request_rec->subprocess_env/ 
table but it didn't work and I can't really say I know what I'm doing.
Any idea on how I might feed that value to the other module? Which hook 
should I handle and which function should I use?
Thank you in advance.
