No.root process opens port 80, but never listens to it, so no user will actually enter the site with root rights. If
you kill the root process, you will see the other sub-process disappear as well.

service httpd stop -- works fine, if you have added apache as one of the service in your config.
apachectl stop      -- use this if you want to stop apache through apache's way.

Gracefully  restarts  the  Apache httpd daemon. If the daemon is not running, it is started. This differs from a
normal  restart in  that  currently  open  connections  are not aborted. A side effect is that old log files will  not
be  closed  immediately. This  means that if used in a log rotation script, a substantial delay may be necessary to ensure that  the  old  log  files  are closed before processing them. This command automatically checks        
    the configuration files as in configtest before initiating  the restart  to  make sure Apache doesn?t die.
This is equivalent to apachectl -k graceful.
( excerpt from manual page of apachectl )
Actually it sends a SIGUSR1 for a restart. The USR1 or graceful signal causes the parent process to advise the children to exit after their current request (or to exit immediately if they're not serving anything). The parent
re-reads its configuration files and re-opens its log files.As each child dies off the parent replaces it with a child
from the new generation of the configuration, which begins serving new requests immediately.

It defines whether Apache should spawn itself as a child process (standalone) or keep everything in a single process (inetd). Keeping it inetd conserves resources. This is deprecated, however.

This module creates dynamically configured virtual hosts, by allowing the IP address and/or the Host: header of the HTTP request to be used as part of the pathname to determine what files to serve. This allows for easy use of a huge number of virtual hosts with similar configurations.

htpasswd is used to create and update the flat-files used to store usernames and password for basic authentication of HTTP users. If htpasswd cannot access a file, such as not being able to write to the output file or not being able to read the file in order to update it, it returns an error status and makes no changes.

In case of ambiguity deny always takes precedence over allow.

Apache Web Server package does not include ASP support.
However, a number of projects provide ASP or ASP-like functionality for Apache. Some of these are:
--> Apache::ASP
--> mod_mono
--> Chilisoft ASP
