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 !
