dragonchild,

As mentioned previously, with mod_perl you can use <Perl> sections, etc. to do this. If mod_perl is not available, another option is to use environment variables and <IfDefine> sections. You can then set these environment variables from the apachectl, with the -D option. for example:

HTTPD="/path/to/httpd -f ... -DFOO"
[download]

The FOO can also be set in the apachectl by an environment variable, etc. Then inside the httpd.conf:

<IfDefine FOO>
specific conf for FOO or...
Include conf/FOO_conf.conf
</IfDefine>
[download]

Other sections could also be added for <IfDefine BAR>, etc. Hope this helps!
