Update 2011-06-04: As it turns out, I never ran this module for long. It does appear to operate as advertised but I found I no longer really had a need to run privilege-separated httpd processes. Still, I hope someone finds this information useful.
If you’ve longed for the days of Apache 1.3 when you could run virtualhosts as different users/groups, well mod_itk is for you and me. It’s based on prefork and the author claims its running on production boxes, so hopefully this will bring back the good ol’ days.
This page was very helpful in combination with the homepage for me.
I’ve patched my server and am running this domain and newsx.org using their own users. All the other virtualhosts are running with default privs.
I really hope this works out because I’ve been wanting it for a long time.
