The first one, is by using Flags. You can type in [R] or [R=301] at the end of the rewrite code line. For example:
RewriteRule ^(aboutus)$ aboutme.php [R=301]
Other use of the [R] or [R=301] flags is whenthere are special cases, like, when your web page address changed and there are still many traffic coming in from the old address. You can't just kill the link, but you can give the browser the correct message by telling that web page has moved temporarily to the URL given. [R] flag is for temporary change of address and [R=301] flag is for permanently been changed.

RewriteRule ^(aboutus)$ http://www.luqmanmarzuki.com/aboutme.php
