External properties file for constant values

This is a feature request.

It will be nice to have some mechanism to include configuration.properties file 
to define constant values such as "domain".

For example:
configuration.properties
domain=myDevDomain.com
subdomain=tv.myDevDomain.com

<rule>
   <condition name="host">${domain}</from>
   <from>/video/(.*)</from>
   <to>subdomain/$1</to>
</rule> 

What do You thin about it?

Please mail me if you need any help or suggestions.

Thanks,
Michał
