Server Configuration
(httpd.conf)
Unless you are the server administrator, you generally will not
have access to this account. On the DCE systems, you do not have
read or write access to this file. Server configuration is read at
server start or restart.
Per Directory (.htaccess)
Certain configuration directives for Apache can be placed within
per-directory.htaccess files.
.htaccess file is read on a per request basis.
