apache httpd.conf constants?

Is there a way to decalare and use constants in a httpd.conf file? I haven't seen anything on it, but it would make migrating my file to other environments MUCH easier!

what kind of thing are you actually trying to achieve? there are a lot of variables that get set in there.

i want to use the same httpd.conf file on multiple servers. Right now, when i migrate i need to change values for
NameVirtualHost
the VirtualHost tag
'Allow from' lines
ServerName
ServerAlias
Listen IP
names of my log file
...

It becomes a large 'find and replace' exercise.

what i am looking for is a way to declare these at the top of the file and use them throughout. here is the basic idea

Code:

<property name="ipaddress" value="192.168.1.123" />
<property name="server1" value="www.superball.com" />

NameVirtualHost ${ipaddress}
<VirtualHost ${ipaddress}:80>
ServerName ${server1}
...

Does apache support this type of functionality?

well no you can't do that, but things like virtualhost declarations don't require ip addresses if there's only one. also can't see a logic in needing to change a virtualhost server name in multiple locations either. you could certianly build a template file to replace yourself, but i'm still not sure why you'd need to do this on a properly conifigured apache instance.
