If I'm understanding what you're asking, generally if you make changes to Apache; e.g., editing
httpd.conf, you need to stop and restart Apache to see those changes (you can execute
apachectl restart as root for example). Additionally, if you're viewing with a browser, you need to either clear the browser cache or force page reload (shift-reload-current-page in Firefox) to see any changes. Also, you should be able to see your web page at
http://your-system-name.whatever assuming you've configured
httpd.conf to do so.
Hope this helps some.
