Extended help for httpd.conf

Always use the extended help for httpd. 

httpd -L 

It will display all the httpd.conf directives and the places where they are valid. For a specific directive, it tells all the possible values and where it can be used inside the httpd.conf. This can be very helpful, when you want to quickly know about a particular Apache directive.

Below is the “httpd -L” output from my server.
