Rather than coding a bunch of near-identical rules like this, a more complex but more efficient solution is available if you need to do more than just a handful or redirects.
This code is for use in example.com/.htaccess. This example code also assumes that you already have other working mod_rewrite rules, that you do not mix mod_alias directives like "Redirect 301" with mod_rewrite directives (or that you stop trying to do so, because it can cause big trouble), and that your rules are all in the proper order.
