found an article, in that says, that content-filtering products must make real-time analysis, and don't use pre-defined URL databases. We always use real-time analysis in our products (first product was offered to customers 6 years ago).
There are many approaches to the real-time analysis. Some of them use statistical approach, some of them use genetic analysis technics. Statistical techniques are simple to implement, but powerfull, while genetic is more precise, but harder to implement.
