Display Apache Configuration

Is there any way to display the effective configuration values that Apache is using?

I have a cPanel server that uses multiple include files and there are some server-wide settings that are defined in multiple places. I'd like to find a way of confirming which value Apache is actually using while it's running.

mod_info provides what you need, I think.

<Location /server-info>
   SetHandler server-info
   Order deny,allow
   Deny from all
   Allow from 1.2.3.4 # your IP, subnet, whatever
</Location>

More here: http://httpd.apache.org/docs/2.2/mod/mod_info.html

You can also list the configuration of your VirtualHosts (less info than using the above) using the command sudo httpd -S.
