The following method will allow you to mask some of your website’s address.

For example, when someone opens up:

http://yourdomain.com/something

the actual content that will be displayed can be the one under:

http://yourdomain.com/something/else

although the URL in the visitor’s address bar will remain http://yourdomain.com/something.

To achieve this, add rules similar to the ones below into your website’s .htaccess file:

RewriteEngine On
RewriteRule ^something/?$ /something/else/

Make sure to substitute something and else with the directories you use on your website.
