Hi.
I have been reading LinkTrackerFilter class from "Servlets and JavaServer Pages� The J2EE� Technology Web Tier" book's source and some questions arised.
This class extracts a url from the query string then redirects the request to that url and then return statement appears.
At the end of the class, the code increases a static counter then there is a chain.doFilter( ).
The book emphases that the calling to the previous doFilter is important in order to allow other filters, servlets and JSP to handle the request.
Since the code the freely avaible, I will post some snipets here :

How the hell the last two lines would be getting called ? there is a return statement !

Did you look closely at the code? Is the return statement unconditionally always reached?
