I believe there may also be a subtle misunderstanding here:
An Apache Virtual Host is not, by itself, a separate process or thread.
All Apache children processes (pre-fork) or threads (worker) are created
equal; they ALL "contain" all virtual hosts. A Virtual Host is only a
"personality" that the child/thread which is handling the current
request adopts temporarily, to handle this current request. At the next
request, the same child/thread may take the personality of another
Virtual Host.
The only way to "personalise" something "for this Virtual Host", is to
make it totally dynamic, executed on a per-request base.
