Filter has similar kind of life cycle as servlet has. It can intercept request and response. This is covered in HFSJ and importent from exam point of view.

Filters are in chapter 13, keep reading :-) (... at least in the 2nd ed., not sure about the 1st ed.).

The exam objectives (which are linked in the http://faq.javaranch.com/java/ScwcdLinks page) show that -yes, indeed- filters are part of the exam.
