URL Rewrite

My current CMS generates links that look like [login to view URL] and each new page it increments by 1. I would like to rewrite this URL to a more descriptive one, say [login to view URL] or better yet [login to view URL] I do not want to change the current system of how new pages that are created increments by 1. I still find the page numbering system useful. Possibly we can add a new table in MySQL with the alias that will direct it to the correct page. Preferably something that doesn't query the database at all would be nice, since I don't want to add load the server or slow down loading times. This project seems pretty simple.
