Not that I know of - basically, the config file is just a flat text file
that apache reads at runtime and loads a structure with key-value pairs.
There is no mechanism for variable substitution.
An alternative that's widely used is to write a perl-script that
generates the config and to run this script immediately before starting
apache (eg, hack "apachectl" and execute the script right at the top).
You can then get the script to read any variable you like and interpose
it in the config.
