Page 699 of HFSJ book:
A. Filters may be used to create request or response wrappers.
B. Wrappers may be used to create request or response filters.
I think B is correct, but the answer given is A. The explanation given is "terminology reversed"!
Why do you need filters to create wrappers?
but you do use wrappers inside filters to send the wrapped Response to the next Filter or the
servlet resource.
Where am I wrong here? Much help is appreciated.
