BleepingComputer.com: Is this how blogspot finds articles

In blogspot the url is of format : dummy.blogspot.com/how to format computer/ This brings up the article.

I was wondering how can I implement same with PHP, mySQL and Apache. I thought I can use 404 code to do this.

1. I set up .htaccess in Apache to redirect 404 error to document /handler.php
2. In handler.php, I set up php code to query mySQL if the url matches some data. If yes then display it. If not then display a custom 404

This way urls like dummy.com/how to format computer/ can be used for separate articles. Although in real they do not exist.

Am I right in doing this? Or is it done in some other way?

I'm not sure... I know that Wordpress has this option, and it's PHP. Maybe digging through the source will be revealing?
