Using servlet filters, it was possible to deliver the customer's first enhancement with-
out affecting the existing code in any way. However, collecting different information
required for usage tracking would require some coding. But you can integrate a simple
yet powerful out-of-the-box open source solution called Clickstream from Open-
Symphony to achieve this goal. It can be downloaded from

. Clickstream is also based on filters, providing a highly flexible way to track
usage patterns on a web site.
