Requesting explanation of config files in /etc/apache2 (Debian Etch, Apache 2.2.3)
I'm using Apache 2.2.3 on Debian Etch (4.0) and I'd like an explanation or reference to a document that describes the role of each of the configuration files in /etc/apache2/
-rw-r--r-- 1 root root 24175 2007-03-27 13:53 apache2.conf
drwxr-xr-x 2 root root 4096 2007-05-18 18:18 conf.d

-rw-r--r-- 1 root root 10 2007-05-18 18:18 ports.conf
drwxr-xr-x 2 root root 4096 2007-08-20 13:50 sites-available

I know that they are files for configuring the behaviour of the apache web server, for example, how it responds to URL requests. But I thought that all of this was done in only httpd.conf In my configuration, by default, httpd.conf is empty, with much of the configuration in apache2.conf and in a file called 'default' in folder sites-available.
Searching howtoforge.com and its forums and apache.org have so far not given me an explanation of these various files. Sure, the commands and directives within the files are documented reasonably well but nothing is said about in which files these should be placed and in what order and, even, why there are so many different files. The only file mentioned in documentation is httpd.conf
Also it would be useful to be able to find out when Apache reads these files and what it reads within them.
