It's been almost an year now, since the search community introduced the rel="nofollow" attribute. It was a ground breaking technique for spammers and not only, but the question is does it still work?

Let's suppose you are building a small database driven website or web-based application which you need search engine covery for. And this isn't the only reason why you would choose to create a web application with search engine friendly URLs. Another important aspect is the usability of this feature. To achieve this, you could use Apache's mod-rewrite module. This would be one way. Another way would be to implement a sort of URL rewrite engine into your web application's engine.
