yes, the article i think still exists.
what you have to use is the apache directive which will force any requests made to a single file which you define.
and then the rest you deal with the request inside that file using $REQUEST_URI to find out the actual URL the user entered, and explode() to seperate the folders by '/'.
The URL to that article is below:
