If only you had read the signature of the e-mail you just responded to 
regarding top-posting, your question would have appeared below the

Here we go. Global variables. In the prefork MPM, you are going to have 
to use shared memory segments. When you start, the first time you run 
your post config, create a shared memory segment. Then, on the other 
post configs (from inside of each process), attach to the shared memory 
handle, and set a "local" variable to your shared memory structure.
